Abstract:

Abstract Mint oil has many applications including foods, perfumes and fragrances, pharmaceuticals, cosmetics and pest control. This essential oil is easily damaged because of its high sensitivity to environmental conditions such as heat, oxygen, light and reactions with other compounds. Encapsulation provides protection of the oil against these undesirable conditions. This study was aimed at evaluating the characteristics of mint oil encapsulated in polyethylene glycol (PEG 6000) as influenced by mint oil load. Mint oil was encapsulated in polyethylene glycol at four different percentages (5.0, 7.5, 10 and 12.5%) using a melt dispersion technique. The experiment was done in two replicates. The encapsulates were characterized for their morphology, size attributes and thermal properties. Particulate sizes ranged from 281.4 – 569.5 nm and tended to increase with the increase in oil load. Microstructure of the particles examined under scanning electron microscope showed irregular flakes with sizes around 10 μm. These particles contained oil droplets in the sizes of about 200 – 500 nm as confirmed by observation with a transmission electron microscope. The enthalpy of melting of encapsulates were higher than that of mint oil, describing the enhancement of oil stability under thermal conditions. This study provides useful information in developing essential oil encapsulation for use in wider applications.

Abstract:

Field experiments were conducted in 2001 and 2002 to study the effect of date of planting, herbicide, and straw mulch on menthol mint yield and oil quality in northwest India. Menthol mint was planted at three dates (December 10, December 30, and January 20). Diuron was applied prior to emergence at rates of 0.0, 0.4, and 0.6 kg ai/ha, with and without rice straw mulch (6 t/ha). Menthol mint planted on December 30 and January 20 produced more plantlets and dry matter than the December 10 planting. Menthol mint planted on December 10 had higher weed density and weed biomass, and lower menthol mint herbage and oil yield than the later planting dates. Straw mulch application reduced weed density and weed biomass, and increased plantlet population, menthol mint dry matter accumulation, fresh herbage, and menthol mint oil yield. Preemergence (PRE) applications of diuron at 0.4 and 0.6 kg ai/ha increased menthol mint population and crop dry matter accumulation, and decreased weed density and weed biomass compared to the weedy check. Diuron at 0.6 kg/ha increased fresh herbage and menthol mint oil yield over the untreated weedy check, but there were no other differences between the two rates of diuron. Physicochemical properties of menthol mint oil were not affected by any of the three tested factors.

Abstract:

The present research aimed to develop an edible coating incorporated with mint essential oil, evaluate its effectiveness in inhibiting in vitro microbial development, and improve both quality and shelf-life of fresh-cut pineapple. Mint essential oil-containing edible coatings showed in vitro antimicrobial efficiency against Escherichia coli and Salmonella Enteritidis. Titratable acidity, pH, and texture were not affected (P>0.05) by coating or storage time. Mass loss was not higher than 1.0% after the 6th day of storage. No effect of storage time and coating on total soluble solids was observed. Mint essential oil-containing coatings inhibited the growth of yeasts and molds in fresh-cut pineapple. Compared to uncoated and control-coated samples, mint essential oil-containing coatings lessened psychrotrophic bacteria counts throughout storage. Counts of thermotolerant coliforms were not higher than 3.0MPN·g-1 in all treatments, whereas no Salmonella sp. was detected during the 6-day storage. Mint essential oil provided a strong flavor to the fruit, as shown by sensory evaluations.

Abstract:

Two species of mint Mentha piperitha (peppermint) and M. arvensis (Japanese mint) are widely cultivated in Iran, but their response to fertilizer regime has not been evaluated so far. A field experiment was conducted to investigate the effects of different organic and chemical fertilizer treatments [Control, 100% urea (95 kg N ha−1), 75% urea (71.25 kg N ha-1) + 25% vermicompost (3.3 t ha-1), 50% urea (47.5 kg N ha-1) + 50% vermicompost (6.75 t ha-1), 25% urea (23.75 kg N ha-1) + 75% vermicompost (10.1 t ha-1) and 100% vermicompost (13.5 ton ha-1)] on essential oil contents, yield and yield components of the two species of mint. Peppermint provided grater plant height, number of internodes, number of leaf and oil percentage compared with the Japanese mint under study. The results indicated that, irrespective of the mint species, plants treated with combined chemical and organic fertilizer presented taller plants, higher oil contents and oil yield compared with solo chemical or organic fertilizers. Oil percentage and essential oil yield of mint increased significantly under the treatment with 25% urea (23.75 kg N ha−1) + 75% vermicompost (10.1 t ha-1). Plant height and number of leaf increased along the replacement of organic fertilizer with chemical fertilizers. The results showed that there was a positive and significant correlation with leaf number and essential oil yield. Application of vermicompost in combination with chemical fertilizer increased plant height, oil percentage and essential oil in both species, suggesting that organic and chemical fertilizer combination improves performance and environmental sustainability.

Abstract:

The aim of this work was the simultaneous loading of quercetin and mint essential oil (mint oil) in phospholipid vesicles specifically tailored to obtain an antibacterial and antioxidant mouthwash. The vesicles were prepared using soy lecithin and Tween 80 as bilayer components, and a mixture of phosphate buffer solution (33%), propylene glycol (33%) and ethanol (33%) as dispersing phase. The formation of regularly shaped, spherical and unilamellar vesicles was confirmed by cryogenic transmission electron microscopy analyses. Similarly, light scattering results disclosed that the size of the vesicles increased by increasing the concentration of mint oil, but at the same time the high amount of mint oil ensured high stability, as the size of these vesicles remained unchanged during 12 months of storage. All tested formulations were highly biocompatible towards epithelial cells and capable of counteracting oxidative cell damages caused by hydrogen peroxide. Moreover, the vesicles prepared with the highest concentration of mint oil inhibited the proliferation of the cariogenic Streptococcus mutans (S. mutans) and Lactobacillus acidophilus (L. acidophilus).

Abstract:

The toxicity of four commercial insecticides (mineral oil, azadirachtin, phenthoate and abamectin) in addition to mint oil (variety of terpenoids), against the citrus leaf-miner, Phyllocnistis citrella, larvae, was tested under laboratory conditions using the leaf-dipping method. The bioassay data indicated that abamectin was the most toxic insecticide against P. citrella larvae, followed by azadirachtin, phenthoate, mint oil and finally mineral oil. On the other hand, field evaluation showed that the highest larval mortality was 94.79 and 83.87% induced by abamectin and azadirachtin, respectively, five days after the 2nd application. Mineral oil and phenthoate showed a 72.43 and 61.4% mortality respectively, at 11 days after the 2nd application, and finally mint oil, 49.82% three days after the 1st application.

Abstract:

Lactic acid wort-based beverages are functional, non-alcoholic, with low pH value and produced by the fermentation of wort by lactic acid bacteria. They are not well accepted by consumers because of their poor sensory characteristics. Therefore, 0.025 and 0.05 % (v/v) mint (Mentha piperita) essential oil was used as a tool for improvement of lactic acid wort-based beverages organoleptic profile. Wort was produced by 60% Pilsen malt, 20% Vienna malt, and 20% Caramel Munich ІІ malt. It was inoculated with probiotic lactic acid bacteria Lactobacillus casei ssp. rhamnosus LBRC11 at a concentration of 107 cells/ml and fermentation was carried out at constant temperature of 25°C. The dynamics of pH, concentration of viable cells, phenolic compounds and antioxidant activity were monitored and the beverages obtained were evaluated by a tasting panel. The results showed that addition of mint essential oil in concentration of 0.025 and 0.05 % (v/v) inhibited lactic acid fermentation but improved the sensory profile of the beverage obtained only when 0.025% mint essential oil was added. Mint essential oil addition led to an increase in the total phenolic compounds concentration, phenolic acids and flavonoid phenolic compounds, measured by Folin–Ciocalteu and modified Glories method but resulted in a decrease in the antioxidant activity, measured by the DPPH radical scavenging assay, cupric reducing antioxidant power (CUPRAC) and ferric reducing antioxidant power (FRAP). The antioxidant activity measured by the ABTS radical scavenging assay was almost equal for the beverages with and without mint essential oil addition. The results obtained will be used for modeling of lactic acids fermentation with addition of mint essential oil for the production of functional wort-based beverages.

Abstract:

SUMMARYHerbage and oil yields of Mentha arvensis (Japanese mint), M. piperita (peppermint) and M. spicata (spearmint) increased significantly with N fertilization up to 100 kg N/ha and those of M. citrata (bergamot mint) with up to 150 kg N/ha. Plant height, leaf: stem ratio and leaf area index increased with N application; and oil content decreased in all the species. Economic optimum doses of N for M. arvensis, M. piperita and M. spicata were 167, 153 and 145 kg N/ha, respectively and their oil yields expected from the response equation were 190, 103 and 50 kg/ha, respectively. The calculated optimum fertilizer rate for M. citrata was 225 kg N/ha, giving a yield of 193 kg oil/ha. Oil quality did not vary appreciably with N fertilization.

Abstract:

Background Hepatic and neurologic injury developed in two infants after ingestion of mint tea. Examination of the mint plants, from which the teas were brewed, indicated that they contained the toxic agent pennyroyal oil. Methods. Sera from each infant were analyzed for the toxic constituents of pennyroyal oil, including pulegone and its metabolite menthofuran. Results. Fulminant liver failure with cerebral edema and necrosis developed in the first infant, who died. This infant was positive only for menthofuran (10 ng/mL). In the other infant, who was positive for both pulegone (25 ng/mL) and menthofuran (41 ng/mL), hepatic dysfunction and a severe epileptic encephalopathy developed. Conclusions. Pennyroyal oil is a highly toxic agent that may cause both hepatic and neurologic injury if ingested. A potential source of pennyroyal oil is certain mint teas mistakenly used as home remedies to treat minor ailments and colic in infants. Physicians should consider pennyroyal oil poisoning as a possible cause of hepatic and neurologic injury in infants, particularly if the infants may have been given home-brewed mint teas.

Abstract:

Plant essential oils of six aromatic herb species and interspecies hybrids of the family Lamiaceae – chocolate mint (Mentha piperita × ‘Chocolate’), pineapple mint (Mentha suaveolens ‘Variegata’), apple mint (Mentha × rotundifolia), spearmint (Mentha spicata), orange mint (Mentha × piperita ‘Granada’) and strawberry mint (Mentha × villosa ‘Strawberry’) – were investigated for antimicrobial effects against plant pathogenic bacteria: Agrobacterium tumefaciens, Pseudomonas syringae pv. syringae and Xanthomonas arboricola pv. corylina. The screening was carried out in vitro on agar plates filled with the target organism. All essential oils screened exhibited a higher level of antibacterial activity against A. tumefaciens and X. arboricola pv. corylina than streptomycin used as a standard in all tests. The antimicrobial effect of streptomycin and five mint oils was at the same level for P. syringae pv. syringae. There were no significant differences in the influence of the chocolate mint oil on the growth inhibition of all bacteria tested. Plant essential oils from pineapple mint, apple mint, spearmint and strawberry mint showed the weakest antimicrobial activity against P. syringae pv. syringae and the strongest towards A. tumefaciens and X. arboricola pv. corylina. The essential oils from strawberry mint, pineapple mint, spearmint and apple mint had the strongest effect on A. tumefaciens, and the lowest inhibitory activity was exhibited by the chocolate mint and orange mint essential oils. X. arboricola pv. corylina was the most sensitive to the strawberry mint, pineapple mint and spearmint oils. The chocolate mint oil showed the greatest activity against P. syringae pv. syringae.

Abstract:

Field experiments were conducted at Lucknow, India, to study the effect of foliar application of orthophosphoric acid and diammonium phosphate filtrate on the biosynthesis and yield of essential oil in transplanted menthol mint: a foliage rich and vegetatively harvested crop. A foliar spray of 10% diammonium phosphate filtrate on the plants of menthol mint enhanced the biosynthesis of essential oil in the leaves to the extent of 15.6–18.7% over the control. A spray of 0.1% orthophosphoric acid gave an increase in the range 8.0–9.4%. When different varieties of menthol mint were sprayed with 10% diammonium phosphate filtrate, the variety Kosi exhibited 13, 78.3 and 66% higher essential oil yield over the varieties Himalaya, Hariti and Kalka, respectively. At the same concentration of spray, the variety Kosi enhanced the essential oil yield by 60% compared with that of the control. The early transplanted crop (18 March) was found to be good in terms of higher essential oil production by about 31% than the later transplanted crop (31 March). It is recommended that in order to get a high essential oil yield from a transplanted mint crop, a foliar spray of 10% diammonium phosphate filtrate should be applied twice, first in the second week of April and second in the first week of June. The optimum time to transplant mint plantlets in the field is the third week of March. A putative working metabolic model of the phosphate effect on biosynthesis of essential oil in volatile plants has been proposed.

Abstract:

Study on the effect of supercritical extracts of mint (Mentha piperita L.) and clove (Syzygium aromaticum L.) on the oxidative stability of soybean oil is presented. Extracts were obtained using supercritical fluid extraction and then added to soybean oil at two different concentrations. The effect of the extracts on the stability of soybean oil during the storage period was studied by determining the peroxide and acid values. Mint extract (M. piperita) was analyzed by HPLC with MS / MS identification. A total of 21 different biologically active components were identified in M. piperita SC-CO2 extracts. The oxidative stability of the soybean oil samples enriched with supercritical extracts of clove and mint was higher than in the control sample (without addition of supercritical extracts). Supercritical extracts can be recommended as a source of natural antioxidants to extend the shelf life of vegetable soybean oil.

Abstract:

In this study, the effects of distillation methods including hydro-distillation (HD) and microwave hydro-distillation (MHD) on essential oil extractions of Mentha arvensis L. in Lam Dong (LD), Ho Chi Minh City (HCMC), and Ba Ria-Vung Tau (BR) were investigated for the yield and chemical composition of the essential oil. The results showed that the use of MHD (0,075 %) was more effective on oil extraction yield than traditional HD (0.053 %). Optimal Distillation parameters were found distillation times of 20 and 110 minutes and material/water ratio of 1:2,5 and 1:6 g/mL for MHD and HD, respectively. The MHD method was subjected to comparing qualitative chemical compositions from Japanese essential oils in BR, LD, and HCMC, Vietnam. The GC-MS analysis results showed that menthol was a major constituent in the essential oil and was responsible for the distinctive smell and flavor of the Japanese mint. Moreover, the menthol content in oil from LD ound was up to 70.6 % higher than that in HCMC (69.45 %) and BR (67.85 %). In conclusion, the mint essential oil is distilled from ingredients in different regions of Vietnam, such as LD, HCMC, BR-VT, all give essential oil a characteristic scent and a relatively high menthol content of about 60 % - 70 %.

Results of the first trial conducted on menthol mint (sole crop) in the fields of 45 farmers clearly indicated that 75% of the chemical fertilizer inputs can be reduced by supplementing the fields with 5tha−1 of menthol mint VC leading to higher levels of profits to the farmers by significantly improving herb and oil yield (6.7 and 8.4%, respectively) compared to the full recommended dose of chemical fertilizers (NPK 75:60:60kgha−1). The second trial was conducted in the fields of six farmers adopting a menthol mint cropping system (mint–rice–wheat–mint) where significantly higher yields were recorded in plots supplemented with 5tha−1 of menthol mint VC+25% of the recommended dose of chemical fertilizers; an increase of 5.6–7.2% in mint oil and 6.6% in wheat yield over the plots receiving the full recommended dose of chemical fertilizers (NPK 75:60:60kgha−1). However, in the case of rice, the highest grain yield was observed within plots receiving the full recommended dose of chemical fertilizers. Data obtained on soil properties clearly showed that apart from enhancing the yields of crops, the integration of VC with chemical fertilizers considerably improved the soil fertility/sustainability status in terms of organic carbon, available N, P and K.

Abstract:

Mint is an industrial plant that is a good source of essential oil and many phenolic compounds that have several positive benefits to human health and can be used to prevent the development of many diseases. The aim of this research was to investigate the possibility of increasing essential oil and flavonoid content, changing the chemical composition of these compounds in different mint cultivars under foliar application with precursors (phenylalanine, tryptophan, and tyrosine) at two concentrations, 100 and 200 mg L−1, to enable the possibilities for wider use of these plants when they are grown in field conditions. Spraying with phenylalanine at 100 mg L−1 concentration increased essential oil content in Mentha piperita ‘Granada’ plants by 0.53 percentage units. Foliar application with tyrosine solutions at 100 mg L−1 concentration most effectively influenced the essential oil odor profile Mentha spicata ‘Crispa’. The highest number of total flavonoids was in Mentha piperita ‘Swiss’ sprayed with tyrosine at 100 mg L−1 concentration. The flavonoid content depended on the mint cultivar, amino acids, and their concentration. The results showed that the effect of amino acid solutions on different secondary metabolites’ quantitative and qualitative composition differed depending on the mint cultivar; therefore, amino acids and their concentrations must be selected based on the cultivar they are targeting.

Abstract:

The objective of this research was to determine chemical composition and to evaluate the antifungal activity of essential oil of Mentha piperita. By the application of GC/MS analysis of essential mint oil, 27 components were identified. The major components were menthol (39.9 %), menton (23.51 %), menthyl acetate (7.29 %), 1.8-cineol (5.96 %), isomenton (5.24 %), isomenthol (3.17 %), trans-caryophyllene (2.88 %), limonene (2.14 %), pulegon (1.38 %), beta-pinene (1.14 %) and piperiton (1.03 %). The quantitative structure? retention relationship (QSRR) was employed to predict the retention time (RT) of Mentha piperita essential oil compounds obtained in GC/MS analysis, using twelve molecular descriptors selected by genetic algorithm. The selected descriptors were used, as inputs of an artificial neural network, to build an RT predictive QSRR model. The coefficient of determination was 0.983, during training cycle, indicating that this model could be used for prediction of RT values for essential oil compounds in Mentha piperita essential oil extracts. Essential oil of Mentha piperita showed antifungal activity on all tested isolates in the minimal inhibitory concentration range of 0.2?1.7 ?l/ml and a minimal fungicidal concentration (MFC) range of 1.7?454.5 ?l/ml. The most powerful antifungal activity of mint was observed in C. cladosporioides of MFC value 1.7 ?l/ml. P. aurantiogriseum showed the lowest sensitivity of MFC value 454.5 ?l/ml.

Abstract:

Biomolecules and extracts from natural products are gaining increasing interest due to their beneficial properties for human health, low toxicity, environmental compatibility and sustainability. In this work, keratin, chitosan and peppermint essential oil have been used for the preparation of coatings on titanium substrates for biomedical implants/devices. All these coatings were obtained from local natural products/byproducts: keratin from discarded wool, chitosan from shrimp shells and peppermint essential oils from a local production. The above cited molecules were selected for their ability to stimulate soft tissue adhesion (keratin), anti-inflammatory activity (chitosan) and antibacterial activity (keratin after metal ion doping, chitosan and mint oil). The coatings were characterized by means of SEM-EDS, FTIR, zeta potential, wettability, tape and scratch tests, and cell and bacteria cultures. The coatings were successfully obtained for all the considered natural substances with good adhesion to the titanium substrates. All the coatings are chemically stable in water and the continuous coatings are mechanically resistant and protective for the metallic substrates. The keratin coatings are hydrophilic while the mint oil and chitosan coatings are hydrophobic; nanofibers, instead of continuous coatings, behave as more hydrophobic. At the physiological pH, the keratin and mint oil coatings are negatively charged when in contact with an aqueous environment, while the chitosan ones are positively charged. The oriented keratin fibers are able to drive fibroblast alignment. The Ag-doped keratin fibers and mint coating show antibacterial properties.

Abstract Essential oils as feed additives are being investigated for promoting health in piglets due to their anti-inflammatory activity. The objective of the study was to measure the in vitro anti-inflammatory effects of peppermint oil and spearmint oil with porcine alveolar macrophages as host immune responses. Briefly, macrophages were harvested from the bronchial lavage of 6 pigs at 6 weeks of age, and then seeded into 24-well plate with at 106 cells/mL. After 24 h incubation at 37oC and 5% CO2, cells were treated with mint oil or lipopolysaccharide (LPS) by randomized complete block design with 12 replicates. The treatments were 2 × 5 factorial arrangement with 2 doses of LPS (0 or 1 μg/mL) and 5 doses of mint oil (0, 25, 50, 100, 200 µg/mL). The supernatants were collected after another 24 h incubation to measure the concentration of tumor necrosis factor alpha (TNF-α) by ELISA assay. Cell viability was also tested by the MTT assay. Data were analyzed using the MIXED procedure of SAS 9.4. Administration of both mint oils and LPS did not impact the PAM cell viability of macrophages. LPS challenge significantly stimulated (P < 0.05) TNF-α secretion from macrophages. In the non-challenge group, peppermint oil reduced (P < 0.05) TNF-α production at 25, 50, and 100 μg/mL, whereas spearmint oil reduced (P < 0.05) TNF-α concentration from 50 to 200 μg/mL. In the LPS challenge group, both mint oils linearly inhibited (P < 0.001) TNF-α secretion from LPS-challenged macrophages with 200 μg/mL as the strongest dose. Results of the current study indicated that both peppermint and spearmint oils had anti-inflammatory activities in vitro. In vivo animal trials will be conducted to evaluate their impacts on animal health and performance.

Abstract:

Background: Plant growth generally requires both macronutrients and micronutrients. One of the most important micronutrients for plants is zinc. Zinc is an essential nutrient for every life form, including plants. In particular, zinc aids enzymatic processes and many biochemical reactions. When plants receive an inadequate amount of zinc, it leads to the loss of imperative biochemical reactions, which is also related to inhibition of plant growth. Therefore, the yield of the plant is relatively low. Interestingly, some scientific evidence have demonstrated a positive relation between zinc intake and the amount of essential oil and yield of plants. Mentha cordifolia Opiz., kitchen mint, is one of the top seven vegetables consumed in Thailand. The increase of some essential minerals in plants or biofortification during plantation has resulted in the increase of essential oils and chlorophyll. The bioactive compounds of essential oil provide antibacterial benefits. Additionally, chlorophyll can be utilized for against sinusitis, purifying the blood, and cleansing of toxins from intestines.Objective: Our study aimed to evaluate the effects of fortifying zinc into plantation soil on growth characteristics, essential oil droplets, and overall quality of Mentha cordifolia Opiz. Methods: Mentha cordifolia Opiz were planted in soil fortified with ZnSO4 at 0 (control), 100, and 200 ppm and grown for 3 months. During the growth period, physical characteristics were observed. After harvesting, proximate analyses were conducted as well as determination of minerals, and chlorophyll content, were conducted. Microbiological and sensory tests were also performed. Results: The increase of growth characteristics correlated with the increase of zinc concentration. The sizes of mint leaves were larger, the stalks were plumper, and the length of the roots were longer—although not significantly different—and the production of essential oil significantly increased. The approximate composition contents including protein, fat, ash, and fiber of plants grown in fortified ZnSO4 soil, increased when compared to the control. The leaves grown from the soil containing the 100 ppm ZnSO4 treatment possessed the highest chlorophyll content, related to lowest in a* value. Overall, the kitchen mint fortified with 100 ppm ZnSO4 seemed to be the most tolerable sample when analyzed for color and sensory attributes. Furthermore, it was discovered that 200 ppm ZnSO4 treatment demonstrated the highest production of essential oil and lowest number of microorganisms.Conclusion: In conclusion, soil fortified with ZnSO4 at 100 ppm during seeding increased greenness, chlorophyll content, and consumer acceptability of the mint leaves. Darker and larger oil droplets were found in the mint leaves obtained from plants grown in soil fortified with 200 ppm ZnSO4.

Abstract:

Development of Mentha piperita L . on biosolids amended soil with levels equivalent to 0, 28, 56 and 112 t ha-1 was evaluated. In order to measure the productivity and its relation with mint essential oil yield, different indices were determined: leaf area, total and several organ dry matter, leaf area ratio, specific leaf area, net assimilation rate and relative growth rate at 30, 44, 58, 72 and 86 days after planting (DAP), and essential oil yield at 90, 110 and 120 DAP. Physiological indices revealed that biosolids prolonged the vegetative phase of the plants, which adapted themselves to the presence of biosolids with time. Plants showed inverse behaviors in relation to productivity, resulting from the primary metabolism, represented by the shoot dry matter yield, and oil yield, resulting from the secondary metabolism. Adaptation of the mint plants to the growth on biosolids could be due to a phytoremediation function of this species. The intrinsic mechanisms of these processes could be better understood in a further evaluation of residual effects in mint plant shoots.

Abstract:

It is necessary to evaluate the variety samples of the crop to obtain the parental material of menthol mints, which will have a high content of essential oil, and be less affected by various diseases. We evaluated the variety samples of mint for disease resistance at the Voznesenskaya branch of V.S. Pustovoit of All-Russian Research Institute of Oil Crops. In the conditions of the branch in the piedmont area of the Western Ciscaucasia, there were identified diseases such as powdery mildew, rust, anthracnose and Fusarium blight. The studied variety samples were characterized by varying degrees of resistance to these diseases. The most harmful disease for mint is rust, the pathogens of which are the Puccinia menthae Pers. and P. angustata Peck. We identified the parental material for development a variety of peppermint Rozovskaya Aroma by analyzing the variety samples of menthol mint for three years of vegetation. Also, we developed and applied the modified scale for evaluation of resistance to the main diseases for the menthol forms of mint.

Abstract:

The chemical content in essential oils have activities on microbes, biopesticides, pathogenic vector insects in humans and animals, including Mentha arvensis and Mentha piperita (mint plants) which have antifertility and antibacterial effects, Vetiveria zizanoides (vetiver root) as insects repellent, Cymbopogon nardus (lemongrass) has an activity against plant pathogenic bacteria and antifungals, and Rosmarinus officinalis (rosemary) has locomotor activity of mice and antibacterial. Essential oils are effective against target organisms, compatible, safe and non-toxic, so they have enormous potential to be developed as biopesticides in controlling rice pests. On the other hand, pests and diseases are problems that always disturb rice farmers, including in Sukaresmi and Kebon Pedes villages, Sukabumi. Therefore, the use of essential oil plants has been carried out to control rice mouse pests. This has been started from the preparation of seeds to process of planting the four types of essential oils (mint, lemongrass, and rosemary) in the fields as intercrops and the procurement of essential oil distillation sets. Based on observations, the growth and development of essential oil plants as intercropping plants on rice runs normally and its impact on rice pests, especially in mice, is quite significant with not found rats around the planting area.

Abstract Environmental or metabolic heat can increase oxidative stress in sows and may impact suckling pig growth; yeast cell- and oil-based products are used to alleviate oxidative stress. A study was conducted to assess yeast cell and mint oil supplementation in sow lactation diets on sow anti-oxidant status and offspring performance to weaning. A total of 45 sows and gilts (240.7 ± 38.5 kg BW) were assigned to one of 4 diets: Control diet (CON), control + yeast cell at 0.2% (YC), control + mint oil at 10 ppm (MO), and control + yeast cell and mint oil (YCMO). Diets were provided from d 110 of gestation through weaning (21 ± 4 d). Variables evaluated were: sow and piglet growth, litter characteristics at birth, colostrum and milk oxidative status, sow feed intake. Data analyzed as randomized complete block with sow as experimental unit and Tukey’s adjustment as means separation test. There was no effect of maternal diet on sow BW (204.52 ± 43.5 kg) at weaning, piglet birth weight (1.44 ± 0.96 kg), litter size (13.09 ± 6 pig/sow) or sow feed intake (6.32 ± 3.05 kg). Piglets from CON females had lesser gain (P < 0.05) compared with the other groups during the suckling phase (0.23, 0.24, 0.24, and 0.24 ± 0.005 kg in CON, YC, MO, and YCMO group, respectively). Superoxide dismutase activity in sow serum (d110 and weaning), colostrum, and milk was not different among diets and was 39, 59, 45, and 10% lower at weaning than d 110 in CON, YC, MO, and YCMO sows, respectively. Milk glutathione content tended to be lower (P < 0.10) in MO than YCMO sows with CON and YC intermediate (15.2, 32.0, 20.6, and 21.1 U/ml), respectively. Overall, inclusion of yeast cell or mint oil enhanced piglet growth, which may be related to lower sow antioxidant status.

Abstract:

Thermal stabilities of four major components (l-menthol, l-menthone, piperitone, and l-menthyl acetate) of Japanese mint essential oil were evaluated via subcritical water treatment. To improve experimental throughput for measuring compound stabilities, a small-scale subcritical water treatment method using ampoule bottles was developed and employed. A mixture of the four major components was treated in subcritical water at 180–240 °C for 5–60 min, and then analyzed by gas chromatography. The results indicated that the order of thermal resistance, from strongest to weakest, was: l-menthyl acetate, l-menthol, piperitone, and l-menthone. In individual treatments of mint flavor components, subsequent conversions of l-menthyl acetate to l-menthol, l-menthol to l-menthone, l-menthone to piperitone, and piperitone to thymol were observed in individual treatments at 240 °C for 60 min. As the mass balance between piperitone and thymol was low, the hydrothermal decomposition of the components was considered to have occurred intensely during, or after the conversion. These results explained the degradation of mint essential oil components under subcritical water conditions and provided the basis for optimizing the extraction conditions of mint essential oils using subcritical water.

Twenty-two essential oil samples from Germany and Albania were assayed to test their inhibitory and fungicidal activity against Cryphonectria parasitica (Murr.) Barr., the major causal agent of chestnut blight on chestnut trees, using the fumigant macrodilution method. Test concentrations of the oils in air phase were: 0.02, 0.04, 0.08, 0.16 and 0.32 ?l ml-1, and minimum inhibitory and fungicidal concentrations were determined. The strongest activity was shown by two samples of mint oil from Germany and Albania, and black pine at the concentration of 0.02 ?l ml-1 of air for both test isolates (M1 and 4S). The tested plant essential oils also included: eucalyptus, sage, silver fir and cade. Only three samples of EOs (mint (2) and black pine) were lethal to both isolates. Sage and silver fir oils were more toxic to the M1 isolate, while cade and eucalyptus oils were more toxic to the 4S isolate. Fifteen oils: mint (2), black pine, cade, eucalyptus, silver fir, sage, pine (4), oregano, lavender, and rosemary (2), inhibited the growth of Cryphonectria parasitica, and seven oils (two samples of mint, eucaliptus, black pine, sage, silver fir and cade) showed fungicidal effects on the pathogen.

Seventeen mint accessions representing the three species grown for commercial oil production in the United States were characterized using randomly amplified polymorphic DNA (RAPD) analysis. The RAPD profiles readily identified the different Mentha species; calculation of genetic distance, based on the number of shared bands, indicated that M. spicata L. is more closely related to M. × gracilis than to M. × piperita. The RAPD profiles also distinguished among eight peppermint accessions of different geographical origin. However, only limited polymorphism was observed among the most widely grown peppermint and Scotch spearmint cultivars. These results indicate a potential lack of genetic diversity in mint cultivars grown for oil in the United States.

Abstract:

In this study, a small dish concentrator with a cylindrical cavity receiver was experimentally investigated as the heat source of a dryer. The system was examined for operation with pure thermal oil and Al2O3/oil nanofluid as the working fluids in the solar system. Moreover, the design, the development, and the evaluation of the dried mint plant are presented in this work. Also, the solar dryer system was simulated by the SolidWorks and ANSYS CFX software. On the other side, the color histogram of the wet and dried mint samples based on the RGB method was considered. The results revealed that the different temperatures of the solar working fluids at the inlet and outlet of the cavity receiver showed similar trend data compared to the variation of the solar radiation during the experimental test. Moreover, it is found that the cavity heat gain and thermal efficiency of the solar system was improved by using the nanofluid as the solar working fluid. Furthermore, the required time for mint drying had decreased by increasing the drying temperature and increasing air speed. The highest drying time was measured equal to 320 min for the condition of the air speed equal to 0.5 m/s and the drying temperature of 30 °C. A good agreement was observed between the calculated numerical results and measured experimental data. Finally, based on the color histogram of the wet and dried mint samples, it was concluded that intensity amount of the red color of the mint increased with the drying process compared to intensity amount of the red color of the wet mint sample.

Abstract:

India is the world's dominant producer of crude Mentha arvensis oil, and exporter of its processed derivative, natural menthol. This status has been achieved through superior product price competitiveness resulting from progressive agronomic improvements that include a transition from cultivation of this mint as a semi-perennial to an annual crop. This paper describes and analyses recent developments in Indian M. arvensis cultivation.Observations were made during 1998/99 and 1999/2000 in the fields of 295 farmers in the central Indo-Gangetic plains area. The criteria recorded included: mint cultivars used; the planting, weeding, irrigation, pesticide application and harvesting schedules; crop health in relation to diseases and pests; yields of the harvested herb and the distilled essential oil; the oil menthol content; and the net income.Most of the farmers used the cultivar, Kosi. The performance and returns of Kosi transplanted in April had proved superior to Kosi and Shivalik suckers and to transplanted Shivalik. The returns from late-transplanted Kosi were in the range of Rupees (Rs) 25 000 to Rs 40 000 ha−1 (Rs 50≈US$1), similar to those from Kosi suckers and much higher than for both transplanted and suckers of Shivalik. This survey revealed that rotations of rice (Oryza sativa) with chickpea (Cicer arietinum) and mint, and pigeonpea (Cajanus cajan) with wheat (Triticum aestivum) and mint could be profitable in the central Indo-Gangetic plains. They also conserved inputs and were preferable to the conventional rice-wheat rotation. A re-survey in the summer of 2002 confirmed that recommendations made to farmers have led to the adoption of the Kosi and Himalaya cultivars in 80% of the survey region and that 70% of mint cultivation in the area occurs in the summer season.

Abstract:

Heat stress affects the yield of medicinal plants and can reduce biomass and/or metabolite production. In order to evaluate the effect of heat-induced stress on the essential oil production in Mentha x piperita L. var. Mitcham (Mitcham mint) and Mentha arvensis var. piperascens Malinv. ex L. H. Bailey (Japanese mint), we studied the chemical composition of the oils of the two mint species under different heat shock stresses in growth chambers. The antibacterial activity of the essential oils was also evaluated; microscopic observation (fluorescence and electron transmission) was used to assess the effect of the tested samples on bacterial growth. The results obtained shed light on the mint essential oils composition and biological activity in relation to heat stress.

Bypass Krian KM 33 Balongbendo, Sidoarjofaridamph@gmail.com Hp. 08123248102 ABSTRACT Polluted air and contaminated seeds can cause various lung diseases, one of which is indicated by cough changes. Coughing into body shape, occurs as a response from the body to irritation in the throat due to mucus, dust, smoke and air outside the body. Nebulizer is an alternative tool to relieve the cough response to the presence of mucus which is an inflammatory reaction due to infection in the respiratory tract. Mint oil in the form of extracts has a variety of esters, especially menthyl acetate and monoterpenes which produce a distinctive aroma that is beneficial for breathing. The aim of the study was to examine the effect of adding mint oil as a result of distillation on the liquid with the nebulizer in cough handling. This study was a pre-experimental study with nonrandomized design pre test and post test with control group design which was used to determine the effect of the addition of mint oil as a result of distillation on the liquid with nebulizer to reduce the coughing status of the patient which included (cough frequency, onset of inflammation, wheezing, and ease of expectoration of phlegm). The results showed that the cough frequency status is known to have decreased from 44.4% of patients to 23.5% of patients. Similarly, the status of inflammation decreased from 41.7% to 21.7%; wheezing status which was originally 58.3% decreased to 39.1%; easy expectoration status also shows that mint oil can reduce the level of difficulty of phlegm to go out to 13% from 36.1%.

Abstract:

Abstract Social and dietary stress at weaning can increase oxidative stress in piglets and impact performance during the early post-wean period. A study was conducted to assess yeast cell and mint oil supplementation during suckling and post-wean periods on offspring growth performance. A total of 481 piglets (6.25 ± 3.35 kg BW) from 45 sows were randomly allotted to pens balanced by weight and litter (6-8 pigs/pen) within maternal diet. Pens of pigs received the same dietary treatment as the sow during the suckling phase: control diet (CON), control + yeast cell at 0.2% (YC), control + mint oil at 10 ppm (MO), and control + yeast cell and mint oil (YCMO) for 35 d post-wean in a 4-phase feeding regimen (phase 1, d0-6; phase 2, d7-13; phase 3, d14-19; phase 4, d20-35). Performance was analyzed as randomized complete block with pen as experimental unit and Tukey’s adjustment as means separation test. Piglets from YC sows were heavier (P < 0.05) than CON with MO and YCMO intermediate at weaning (6.9, 6.5, 6.7 and 6.6 ± 0.2 kg, respectively) and day 6 post-wean (7.12, 6.68, 7.01, and 6.75 ± 0.09 kg, respectively) and no difference among groups at day 13 (9.1 ± 0.16 kg), 19 (11.3 ± 0.19 kg) and 35 (19.7 ± 0.35 kg). Overall, daily gain was greater (P < 0.05) CON-fed pigs than YCMO pigs (0.40, 0.39, 0.38, 0.37 ± 0.01 g/d in CON, YC, MO, and YCMO, respectively). Overall feed intake was greater (P < 0.05) for YCMO than MO resulting in lower (P < 0.05) gain:feed in YCMO-fed pigs vs CON and MO with YC-fed pigs intermediate (0.538 vs 0.617, 0.621, and 0.585, respectively). Exposure to yeast cell or mint oil during the suckling and early post-wean periods provided some benefit to offspring performance.

Abstract:

Mentha arvensis or mint is a renowned medicinal and aromatic plant. It is annual plant and cultivated in the tropical and sub-tropical regions under irrigation. Its cultivation has significant importance, such as for food flavoring, medicinal applications, essential oil applications, and also using in traditional purposes. Its essential oil contains many components phenolic, aldehydes, ketones, and carbohydrates. Menthol is a fundamental component of Mentha arvensis essential oil. Menthol has also several industrial applications, especially in food, cosmetics, pharmaceuticals, and by-products. There are many types or variations of menthol found in Mentha arvensis depending on the species or cultivars as well as cultivation conditions, such as weather, irrigation, soil type, pruning, and other agronomical practices. It has interesting and valuable botany, morphology, and ecology. Its growth rate is strongly affected by the change of variables, such as pH, temperature, and nutritional values of soil. The extraction of essential oil and the post-harvest analysis are done by using traditional methods for Mentha arvensis oil production in developing countries. Research on oil extraction methods, maximizing yield per hectare, and optimum preservation are needed for the further, especially in post-harvest of mint leaves and roots.

Abstract:

This work aimed to evaluate the production of fresh and dry mass of leaves, stems and aerial parts, and the content and quality of lemon mint (Mentha x piperita var. citrata) essential oil as a result of four potassium (K) concentrations (276, 414, 552 and 690 mg.L-1) under hydroponic solutions. The experiment was carried out in the hydroponic NFT (Nutrient Film Technique) system. Leaves were separated and weighted to determine the fresh mass and part of them was used to extract oil in a Clevenger apparatus. The analysis of the oil chemical composition was performed in a gas chromatograph fitted with a mass spectrometer. The estimated concentration for the maximum fresh mass production of the leaves corresponded to 384 mg.L-1 K. The greatest K concentration proportionated an increase in essential oil content and yield per plant, but decreased linalool and linalyl acetate in the oil. Under the conditions the experiment was carried out, in order to obtain an adequate quantity of leaves for a higher essential oil yield per plant and linalool and linalyl acetate accumulus, the K concentration of 414 mg.L-1 is recommended in the hydroponic solution for the cultivation of lemon mint.
