Abstract:

Eucalyptus oil is used in a wide range of medicinal and other uses, and the current study aims to estimate the median lethal dose LD50 of eucalyptus oil of Eucalyptus camaldulensis and estimate the pathological effect of eucalyptus oil in mice. Eucalyptus oil was obtained in the study by extracting the leaves of the plant Eucalyptus camaldulensis using hydrodistillation. Toxicity testing was performed by dividing mice into groups that you treated with different doses of eucalyptus oil 1200, 1600, 2000, and 2400 mg/kg. The current study showed that the average lethal dose, the LD50, was 1820 mg/kg. The study suggested the emergence of clinical signs in mice when consuming eucalyptus oil in high doses, such as slow movement, suffocation, and convulsion, compared with the control group and the group that administered a lower dose, It was observed that high doses of eucalyptus oil could cause damage to the lung, liver, kidneys, and heart, as the lung was the organ most affected by the oil, followed by the liver, kidneys, and then the heart, and it was less affected by eucalyptus oil, and this indicates that eucalyptus oil, when administered orally in high doses, causes clear toxicity effects. Eucalyptus oil is a safe medicine for external use. Keywords. Eucalyptus oil, LD50; Administrated; Lung; Liver; Heart; Kidney; Mice.

Abstract:

Eucalyptus oil has been reported effective in reducing pain, swelling, and inflammation. This study aimed to investigate the effects of eucalyptus oil inhalation on pain and inflammatory responses after total knee replacement (TKR) surgery. Participants were randomized 1 : 1 to intervention group (eucalyptus inhalation group) or control group (almond oil inhalation group). Patients inhaled eucalyptus or almond oil for 30 min of continuous passive motion (CPM) on 3 consecutive days. Pain on a visual analog scale (VAS), blood pressure, heart rate, C-reactive protein (CRP) concentration, and white blood cell (WBC) count were measured before and after inhalation. Pain VAS on all three days (P<.001) and systolic (P<.05) and diastolic (P=.03) blood pressure on the second day were significantly lower in the group inhaling eucalyptus than that inhaling almond oil. Heart rate, CRP, and WBC, however, did not differ significantly in the two groups. In conclusion, inhalation of eucalyptus oil was effective in decreasing patient's pain and blood pressure following TKR, suggesting that eucalyptus oil inhalation may be a nursing intervention for the relief of pain after TKR.

Abstract:

Most Eucalyptus plantations in Brazil aim the production of paper and charcoal, but the use of the species for lumbering, construction and extraction of essential oil has increased. Eleven species of Eucalyptus were assessed in regard to their essential oil production potential, nine never used before for commercial, essential oil extraction. Assessements were compared with Eucalyptus citriodora and Eucalyptus globulus, already explored in oil production for perfume and medical purposes, aiming to increase the availability of commercial species and the relationship between oil production and climatic conditions. Eucalyptus leaves were seasonally sampled (three months interval) for distillation and determination of productivity and chemical composition of oil - contents of oils main components. Eucalyptus viminalis showed the highest potential for cineol, and standed out among the species not yet used commercially. Influenced by soil moisture contents and air temperature, the lowest and the highest oil production happened respectively in Spring and Summer. Water deficiency in Spring caused the lowest oil production. In the Summer, on the other hand, the highest oil production was observed when temperatures were higher and no water deficiency registered. There was no climatic influence on the main oil chemical component.

Abstract:

Abstract Eucalyptus oil is a commonly used remedy for common colds. For a substance to be effective therapy in obstructive airway diseases, it must reduce the viscosity of respiratory mucus. The present study evaluates the effectiveness of eucalytpus oil added phospholipid mixtures as possible substitute therapies in diseases of altered mucus viscosity by studying their effect on the viscosity of mucus gel simulants in vitro. Test formulations of surfactants consisting of phospholipid-eucalyptus oil mixtures in the ratio of 1 part of oil to 9 parts of phospholipid were prepared. The phospholipids used were dipalmitoyl phosphatidylcholine (PC), phosphatidylethanolamine (PE) and phosphatidylglycerol (PG). The effects of these phospholipid-eucalyptus oil mixtures on the viscosity of Mucus Gel Simulant (MGS – a polymeric gel consisting mainly of gum tragacanth and simulating respiratory mucus) was studied by application of steady shear rates ranging from 0.512 to 51.2 s−1 in a concentric cylinder viscometer at 37°C. The change in MGS viscosity, after incubation with surfactants, with application of shear rates was found to have a Non-Newtonian flow and to follow the power law model with R2 values > 0.8. The addition of eucalyptus oil-phospholipid mixtures caused a decrease in the MGS viscosity when compared with the effect of the phospholipid alone at both low and high shear rates. The combination of PG with eucalyptus oil and of PG with eucalyptus oil and calcium caused ratios of change in MGS viscosity < 1, i.e. they caused a decrease in the MGS viscosity. Thus, the addition of eucalyptus oil improved the ability of the phospholipids to alter MGS viscosity. The combinations of PG with eucalyptus oil and PG with eucalyptus oil in the presence of calcium were even capable of lowering mucus gel viscosity and should be further researched as possible substitute therapies for diseases of altered mucus viscosity.

Abstract:

Eucalyptus (Eucapyptusspp.), an evergreen tall tree native to Australia and Tasmania, has been used since ancient times by the aboriginal population for several purposes. In particular, the speciesE. globulusis widely used in the pulp industry, as well as for the production of eucalyptus oil extracted on a commercial scale in many countries as raw materials in perfumery, cosmetics, food, beverages, aromatherapy and phytotherapy. The 1,8-cineole (eucalyptol), the principal and the most important constituent extracted from eucalyptus leaves, demonstrated an antimicrobial and anti-inflammatory activities. Despite the fact that the healthy effects of eucalyptus have been well established by research, further studies are necessary to investigate other prime effects of the plant and its possible implication in the treatment of a greater number of pathological conditions.

Abstract:

Essential oils such as eucalyptus oil are widely used as antioxidants, antimicrobial, anti-inflammatory, fragrance, and other medical needs. This oil is extracted from eucalyptus terpenoid compounds, e.g., cineole. This study aims to evaluate the effect of the leaf storage time and distillation time (DT) on Eucalyptus grandis essential oil yield and quality. Three DT treatments (i.e., 2 h, 3 h, and 4 h) and storage time of eucalyptus leaf in warehouse (i.e., 2 h, 3 h, and 4 h) were applied on eucalyptus leaf samples. The quality of the eucalyptus essential oil was determined using cineole content, solubility in alcohol, and optical rotation. The essential oil yield ranges between 0.165-0.220%, with the maximum yield of 0.220% on 3 days of storage and 4-hour distillation time. The cineole content ranged between 10-30% and the highest at 3 h DT with a storage time of 2 days. The optical rotation on the tested specimen showed that the index of refraction produced in oil projections was positive. The samples in all treatments showed high solubility in alcohol. This study showed that storage time of 3 days and 3-hour distillation time resulted in the most optimal eucalyptus essential oil yield, and the excellent quality of oil produced has a high potential for health product applications.

Abstract:

Fuels derived from biomass are mostly preferred as alternative fuels for IC engines as they are abundantly available and renewable in nature. The objective of the study is to identify the parameters that influence gross indicated fuel conversion efficiency and how they are affected by the use of biodiesel relative to petroleum diesel. Important physicochemical properties of palm kernel oil and eucalyptus blend were experimentally evaluated and found within acceptable limits of relevant standards. As most of vegetable oils are edible, growing concern for trying nonedible and waste fats as alternative to petrodiesel has emerged. In present study diesel fuel is completely replaced by biofuels, namely, methyl ester of palm kernel oil and eucalyptus oil in various blends. Different blends of palm kernel oil and eucalyptus oil are prepared on volume basis and used as operating fuel in single cylinder 4-stroke variable compression ratio diesel engine. Performance and emission characteristics of these blends are studied by varying the compression ratio. In the present experiment methyl ester extracted from palm kernel oil is considered as ignition improver and eucalyptus oil is considered as the fuel. The blends taken are PKE05 (palm kernel oil 95 + eucalyptus 05), PKE10 (palm kernel oil 90 + eucalyptus 10), and PKE15 (palm kernel 85 + eucalyptus 15). The results obtained by operating with these fuels are compared with results of pure diesel; finally the most preferable combination and the preferred compression ratio are identified.

Abstract:

We evaluated whether phytotoxic effects of the essential oil from Eucalyptus saligna Sm. leaf litter were related to its major compounds 1,8-cineole (eucalyptol) and α-pinene. Effects of the essential oil and its major compounds, combined and alone, were tested on germination and growth of the weed Eragrostis plana Ness. Volatile organic compounds (VOCs) emitted from the essential oil were determined in the airspace of Petri dishes during the experimental period. These volatile fractions were obtained by solid-phase microextraction (SPME) followed by gas-chromatography coupled to mass spectrometry (GC-MS). Effects of the oil and its major compounds were also assessed in aqueous solution on coleoptile growth of Triticum aestivum L. The essential oil showed the strongest phytotoxic effects on E. plana, followed by eucalyptol, eucalyptol + α-pinene, and α-pinene. A similar order of phytotoxicity was observed on coleoptile growth of T. aestivum. The proportion of oxygenated monoterpenes increased along the experimental period, mainly eucalyptol, and of monoterpene hydrocarbons diminished in the volatile fractions. We conclude that phytotoxicity of E. saligna leaf litter essential oil may be mainly related to eucalyptol and additive or synergistic effects of other minor compounds. Analysing VOCs emission is relevant to elucidate compounds involved in phytotoxicity of a plant species.

Abstract:

Present research work evaluates variation in volatile chemicals profile and biological activities of essential oil (EO) obtained from the leaves of eucalyptus ( Eucalyptus camaldulensis Dehnh.) using hydro-distillation (HD) and supercritical fluid extraction (SFE). The yield (1.32%) of volatile oil by HD was higher than the yield (.52%) of the SFE method ( P < .05). The results of physical factors like density, color, refractive index, and solubility of the EOs produced by both the methods showed insignificant variations. Gas chromatography - mass spectrometry (GC-MS) compositional analysis showed that eucalyptol (31.10% and 30.43%) and α-pinene (11.02% and 10.35%) were the main constituents detected in SFE and HD extracted Eucalyptus camaldulensis EO, respectively. Antioxidant activity-related parameters, such as reducing ability and DPPH free radical scavenging capability exhibited by EO obtained via SFE were noted to be better than hydro-distilled EO. Supercritical fluid extracted and hydro-distilled essential oils demonstrated a considerable but variable antimicrobial potential against selected bacterial and fungal strains. Interestingly, oil extracted by SFE showed relatively higher hemolytic activity and biofilm inhibition potential. The variation in biological activities of tested EOs can be linked to the difference in the volatile bioactives composition due to different isolation techniques. In conclusion, the EO obtained from Eucalyptus leaves by the SFE method can be explored as a potential antioxidant and antimicrobial agent in the functional food and nutra-pharmaceutical sector.

Abstract:

Abstract Eucalyptus citriodora oil is an essential oil that contains volatile active compounds. To slow down the process of releasing such volatile compounds, a binding agent such as a polymer matrix is needed. This research aimed to prepare and characterize the properties of Eucalyptus citriodora oil encapsulated in polymer matrices. Development of nanoencapsulated Eucalyptus citriodora was prepared using the melt-dispersion method and polymer matrices (PEG-6000 and paraffin wax) with the addition of Mentha piperita oil as aroma enhancer at a ratio of 1:1. The gas chromatography analysis showed that Eucalyptus citriodora oil contains volatile compounds (citronellal 76.17%). The nanoencapsulated eucalyptus powder produced using the PEG-6000 matrix, in terms of properties, was better than that using paraffin for having smaller particle size and being difficult to agglomerate at room temperature. The average size of oil droplets of nanoencapsulated Eucalyptus citriodora in the PEG-6000 matrix was 235.35 nm with a PDI of 0.339. The morphological analysis using a transmission electromagnetic microscope indicated that the average droplet size was less than 100 nm. This product can be used as a breath-relieving aromatherapy powder by wrapping it in porous paper to be inhaled.

Abstract:

In this study, the application of eucalyptus essential oil/vapour as beverages preservative is reported. The chemical composition of eucalyptus oil was determined by gas chromatography-mass spectrometry (GC-MS) and solid phase microextraction GC-MS (SPME/GC-MS) analyses. GC-MS revealed that the major constituents were 1,8-cineole (80.5%), limonene (6.5%),α-pinene (5%), andγ-terpinene (2.9%) while SPME/GC-MS showed a relative reduction of 1,8-cineole (63.9%) and an increase of limonene (13.8%),α-pinene (8.87%), andγ-terpinene (3.98%). Antimicrobial potential of essential oil was initially determined in vitro against 8 different food spoilage yeasts by disc diffusion, disc volatilization, and microdilution method. The activity of eucalyptus vapours was significantly higher than the eucalyptus oil. Minimum inhibitory concentration (MIC) and minimum fungicidal concentration (MFC) varied from 0.56 to 4.50 mg/mL and from 1.13 to 9 mg/mL, respectively. Subsequently, the combined efficacy of essential oil and thermal treatment were used to evaluate the preservation of a mixed fruit juice in a time-dependent manner. These results suggest eucalyptus oil as a potent inhibitor of food spoilage yeasts not only in vitro but also in a real food system. Currently, this is the first report that uses eucalyptus essential oil for fruit juice preservation against food spoiling yeast.

Abstract:

Common cold is a mild viral infection of the upper respiratory tract, nose, and throat. Common cold suffered by each toddler in Indonesia is predicted to occur three to six times a year, which means that a toddler may experience three to six times of coughs and colds every year. Common cold is also a symptom of Covid-19 whose early treatments used symptomatic and non-pharmacological therapy including tea tree oil and eucalyptus oil aromatherapy. Related to this, this paper reveals the effectiveness of tea tree oil and eucalyptus oil aromatherapy for the healing period of 1 to 2-year-old toddlers in T W Independent Midwifery Practice (IMP). This paper employs quasy experiment design with non-equivalent control group model. Sample includes 14 toddlers with the age of 1 to 2-year-old. Seven of them were given tea tree oil, while the rest were given eucalyptus oil aromatherapy with accidental sampling technique. Aromatherapy was given once a day for seven days. Findings showed that the healing period of the control and intervention group was four to five days and according to the Mann Whitney trial, p-value of 0,530 (0,05) was obtained. In conclusion, there is no difference between the healing period of common cold using tea tree oil and eucalyptus oil aromatherapy for 1 to 2-year-old toddlers in T W Independent Midwifery Practice (IMP). Tea tree oil and eucalyptus oil aromatherapy can be used to accelerate the healing period of common cold suffered by toddlers.

Abstract:

Several Eucalyptus cultivars has been introduced and cultivated for millions of hectares afforestation in subtropical China, whose woods were mainly used in papermaking industry and whose water essential oils were used mainly in aroma and medical industry. However, the potential biomedical components of organic essential oils were still uncovered. In order to reveal constituent characteristic and biomedical potentials of organic essential oils from leaves of four Eucalyptus cultivars (E. camaldulensis,E. tereticornis,E. citriodoraandE. dunnii) in China, their components were efficiently extracted by improved solvents extracting condition, which were identified by optimal gas chromatography / mass spectrometry (GC/MS). The functional analytical results suggested that these four Eucalyptus cultivars possess large numbers of common components, especially including Eucalyptol, 1-Eicosanol, (+)-Longifolene, (+)-Aromadendrene, Phytol and (-)-Alloaromadendrene, which are good materials for aroma and biomedical industry. The contents of common components of four Eucalyptus cultivars are as high as 68.97%, 81.81%, 60.64% and 64.29%, respectively. Moreover, each Eucalyptus organic essential oil also has specific components with potentials in aroma industry or biomedical industry.

Abstract:

This study aimed to determine the volume of traditional eucalyptus oil from distillation with variations in fluid flow velocity. The method of distillation was distillation with water (water distillation). The material was eucalyptus leaves. To determine the volume of eucalyptus oil produced by distillation, the distillation device was set at the height of the condenser to the source of flow fluid, which was at an altitude of 15 cm, 25 cm, 35 cm, 45 cm, and 55 cm. Variation in the height of the condenser would affect the fluid flow rate. The faster the fluid flow rate, the greater the convection coefficient so that it increased the heat transfer rate. This results in greater volume (capacity) of oil produced. From these experimental results, most volumes of eucalyptus oil obtained from the distillation was obtained at 55 cm of the height of condenser with 3.6 mLof oil volume.

Abstract:

Various efforts have been made to eliminate or at least reduce the negative impact of chemical pesticides that are currently widely used. One of these efforts is to use other effective control alternatives, such as bio-pesticides/botanical pesticides. Eucalyptus citriodora essential oil was previously better known in traditional medicine. However, many studies have shown that this essential oil has much potential to be used as a biopesticide. This article reviews the biopesticide potential of E. citriodora essential oil, including its herbicidal, bactericidal, fungicidal, nematicidal, insect-repellent, and insecticidal activities. E. citriodora oil contains citronellal, citronellol, 1,8-cineole, isopulegol, ?-pinene, and citronellyl acetate. Citronellal and citronellol are one of the main toxins in E. citriodora essential oil. However, this review shows that the oil has a broad spectrum of biological activity, making it a simple and environmentally friendly pesticide.

AbstractFilariasis is a mosquito-borne disease that causes lymphedema and the main vector is Culex quinquefasciatus. A simple measure was taken to eradicate the vector using nanoemulsion. Eucalyptus oil nanoemulsion was formulated in various ratios comprising of eucalyptus oil, tween 80 and water by ultrasonication. The stability of nanoemulsion was observed over a period of time and 1:2 ratios of eucalyptus oil (6%) and surfactant (12%) was found to be stable. The formulated eucalyptus oil nanoemulsion was characterized by transmission electron microscopy and dynamic light scattering. The nanoemulsion droplets were found to have a Z-average diameter of 9.4 nm and were spherical in shape. The larvicidal activity of eucalyptus oil nanoemulsion and bulk emulsion was tested and compared. Our nanoemulsion showed higher activity when compared to bulk emulsion. The histopathology of larvae-treated and untreated nanoemulsion was analyzed. Furthermore, biochemical assays were carried out to examine the effect of nanoemulsion on biochemical characteristics of larvae. The treated larval homogenate showed decrease in total protein content and a significant reduction in the levels of acetylcholinesterase. The levels of acid and alkaline phosphatase also showed reduction as compared to control larval homogenate.

Abstract:

Eucalyptus (Eucalyptus camaldulensis) and Myrrh (Commiphora Myrrha) essential oils (EOs) stand out for their benefits in terms of health and functionality. Buffalo set yogurt enriched with different concentrations of EOs (0.3, 0.6, and 0.9%) were investigated. The effects of addition on sensory, syneresis, antibacterial activity, and bioactive properties (total phenol content and antioxidant activity) of yogurt were studied. The most acceptable organoleptic properties of treated yogurt were those samples treated with Eucalyptus oil. The levels of syneresis were decreased by increasing the concentration of EOs. Moreover, the antioxidant activity, antibacterial activity, and total phenolic content were enhanced by increasing the concentration of EOs. Yogurt with 0.9% Eucalyptus oil showed the highest antioxidant activity and total phenolic content. The same concentration of Eucalyptus oil showed the highest antibacterial activity against S. typhimurium (the inhibition zone was 20.63 mm) then E. coli (the inhibition zone was 19.43 mm). On the other hand, the highest antibacterial effect against L. monocytogene was for Myrrh oil-enriched yogurt by 0.9% and the inhibition zone was 19.21 mm. The obtained results showed that Eucalyptus and Myrrh oils can be applied to yogurt to improve its beneficial properties in terms of physical characteristics and for human health due to their antioxidant activity and phenolic materials.

Abstract:

Villagers of Delo and Raekore have a traditional eucalyptus refining business by boiling the eucalyptus leaves for aromatic oils. Eucalyptus oil produced quite well, it's just a long distillation process that is 5 to 6 hours so it requires a lot of wood. While the availability of firewood in the forest is currently quite difficult, so people often cut down trees in the forest. So need to find a solution by changing the way of boiling by steam method and using charcoal fuel made from coconut shell, because it has a higher calorific value than the shell is burned directly. Traditional refined eucalyptus oil products, ranging from 2 to 3 beer bottles (1 bottle of beer = 350 ml) per day, so that through the activities of IbM can apply the appropriate technology products that is the installation of wood crude oil refinery by steam method and the using of briquette fuel. The steamed container produced has a volume of 160 liters while the charcoal briquette printing device is capable of printing 8 charcoal briquettes in one print. The using of refinery installations by steam method and charcoal charcoal fuel, can increase the production capacity of eucalyptus oil to encourage economic improvement of Delo and Raekore villagers. The eucalyptus refining oil refinery has a production capacity of 4 to 5 bottles of beer (1 bottle of beer = 350 ml) per day and charcoal briquette presses have a production capacity of 8 charcoal briquettes.

Abstract:

Eucalyptus (family Myrtaceae), a native plant from Australia, is a genus cultivated due to its oil, gum, pulp and timber used worldwide for different commercial applications. It is a plant with significant economic importance and possibly its cultivation, in Brazil and other countries, has reduced the exploitation of native trees. The secondary metabolism of Eucalyptus, as usually found in plants, produces essential oils and tannins, which may interfere in the consumption of plants by wild animals. The goal of the present work was to investigate the influence of essential oil and tannins concentration on the herbivory of seven Eucalyptus taxa. Essential oils composition for all species investigated were characterized by CG MS HS-Trap analysis. The lowest hebivory rate were associated to Urocam, Grancam and Eucalyptus benthamii. Those taxa were associated with the presence of mix oil compounds, α/β-Pinene, Pinocarveol, α-Terpineol and Tannins. Tannins concentrations and essential oil are an important factor that contributes to the plant protection against herbivory.

Abstract:

This paper presents an experimental study on the effect of different high octane fuels (such as eucalyptus oil, ethanol, and methanol) on engine?s performance behaviour of a biofuel based dual fuel engine. A single cylinder Diesel engine was modified and tested under dual fuel mode of operation. Initially the engine was run using neat diesel, neat mahua oil as fuels. In the second phase, the engine was operated in dual fuel mode by using a specially designed variable jet carburettor to supply the high octane fuels. Engine trials were made at 100% and 40% loads (power outputs) with varying amounts of high octane fuels up-to the maximum possible limit. The performance and emission characteristics of the engine were obtained and analysed. Results indicated significant improvement in brake thermal efficiency simultaneous reduction in smoke and NO emissions in dual fuel operation with all the inducted fuels. At 100% load the brake thermal efficiency increased from 25.6% to a maximum of 32.3, 30.5, and 28.4%, respectively, with eucalyptus oil, ethanol, and methanol as primary fuels. Smoke was reduced drastically from 78% with neat mahua oil a minimum of 41, 48, and 53%, respectively, with eucalyptus oil, ethanol, and methanol at the maximum efficiency point. The optimal energy share for the best engine behaviour was found to be 44.6, 27.3, and 23.2%, respectively, for eucalyptus oil, ethanol, and methanol at 100% load. Among the primary fuels tested, eucalyptus oil showed the maximum brake thermal efficiency, minimum smoke and NO emissions and maximum energy replacement for the optimal operation of the engine.

Eucalyptus oil is an essential oil commonly used as a solvent to remove old gutta-percha when performing endodontic re-treatment procedures. Although commonly used by dentists, evidence for its safety is lacking. This report outlines a previously undocumented case of a 44-year-old male who attended the Oral and Maxillofacial Surgery department with sudden onset facial swelling in response to extrusion of eucalyptus oil through the apex of a tooth during root canal re-treatment by his dentist. The management of this case is discussed and the important safety aspects with regard to the chemicals used in endodontic treatments are reviewed. CPD/Clinical Relevance: This paper highlights that the risk of extrusion injury during endodontic treatment is not limited to the use of sodium hypochlorite but also to other chemicals such as, and in our case, eucalyptus oil.

Abstract:

Abstract A study was undertaken to explore the content and composition of volatile oil from decaying leaves of lemon-scented eucalypt (Eucalyptus citriodora Hook.) not analyzed earlier. GC and GC-MS analysis of the oil (yield 0.6%) revealed the monoterpenoid nature with citronellal (52.2%), citronellol (12.3%) and isoisopulegol (11.9%) as the major constituents. Overall, 17 components were identified that accounted for over 94% of the decaying leaf oil. Surprisingly, the decaying leaf oil contained nearly 1.8% of trans-rose oxide, which is generally absent in eucalypt essential oil. Decaying leaf oil and its major 2 components (citronellal and citronellol) inhibited the germination and root elongation of two weeds D Cassia occidentalis (broad-leaved) and Echinochloa crus-galli (grassy weed). Based on the dose-response studies, I50 values were determined for decaying leaf oil and the effect was more on germination only of broad-leaved weed (C. occidentalis), whereas that of citronellal and citronellol were on germination as well as root length of E. crus-galli (grassy weed). Based on I50 values it was observed that citronellal was more phytotoxic and germination inhibiting in nature, whereas citronellol was a more potent root inhibitor, thereby indicating a possible different mode of action. The study concludes that decaying leaf oil hold a good commercial value for exploitation as weed management agent

Eucalyptus essential oil is extracted from its leave using steam distillation method and formulated in the making of hand sanitizer gel with various concentrations of 2%, 4%, and 6%. The formulation of hand sanitizer gel was tested for antibacterial, organoleptic, homogeneity, pH, and dispersibility. The results showed that the more concentration of essential oil from Eucalyptus botryoides leaves added to the hand sanitizer gel, the more its antibacterial activity increased. The results of organoleptic observations, homogeneity, pH, and dispersibility of hand sanitizer gel preparations have met the requirements of SNI No.06-2588-1992. Thus, essential oil from E. botryoides leaves has potential as an antibacterial in hand sanitizer gel products.

Abstract:

The aim of this study was to investigate the effect of inhalation of eucalyptus oil and its constituents on anxiety in patients before selective nerve root block (SNRB). This study was a randomized controlled trial carried out in 62 patients before SNRB. The patients were randomized to inhale limonene, 1,8-cineole, or eucalyptus oil, each at concentrations of 1% vol/vol in almond oil or almond oil (control). Anxiety-visual analog scale (A-VAS), state-trait anxiety inventory (STAI), profile of mood states (POMS), pain-visual analog scale (P-VAS), blood pressure, and pulse rate were measured before and after inhalation prior to SNRB. Measures of anxiety, including A-VAS (P<0.001), STAI (P=0.005), and POMS (P<0.001), were significantly lower in 1,8-cineole than in the control group and significantly greater in 1,8-cineole than in the eucalyptus group in A-VAS. P-VAS was significantly lower after than before inhalation of limonene, 1,8-cineole, and eucalyptus, despite having no significant difference in the four groups compared with control group. 1,8-Cineole, a major constituent of eucalyptus, was effective in decreasing anxiety before SNRB. The present findings suggest that inhalation of 1,8-cineole may be used to relieve anxiety before, during, and after various operations, in addition to SNRB.

Abstract:

Essential oils, also known as volatile oils, are substances produced through the secondary metabolism of plants. In this study, we determined the chemical composition and the in vitro and in vivo antifungal activity of the essential oils from four species of Eucalyptus, Eucalyptus citriodora, Eucalyptus camaldulensis, Eucalyptus grandis and Eucalyptus microcorys, against the Hemileia vastatrix fungus. The essential oils from these four species of Eucalyptus were extracted from their leaves by the hydrodistillation technique using a modified Clevenger apparatus. The chemical characterization was performed by gas chromatography coupled with a mass spectrometer detector and by gas chromatography using a flame ionization detector. The antifungal activities of the essential oils against H. vastatrix were studied by evaluating the percentage of spore germination using the microdilution test for in vitro assays. The curative and preventive effects were evaluated in in vivo tests. The principal constituents of the essential oil from E. citriodora were citronellal, citronellol and isopulegol, while E. camaldulensis produced 1,8-cineole, α-terpineol and α-pinene. 1,8-cineole, α-pinene and α-terpineol were obtained from E. grandis and 1,8-cineole, α-pinene and trans-pinocarveol were the principal components in the essential oil of E. microcorys. In vitro and in vivo antifungal activities against the fungus under study were observed for most of the essential oils, except the essential oil from E. microcorys, for which no preventive antifungal activity was observed. Only the curing of infection by the H. vastatrix fungus was observed with this oil.

Abstract:

Given the limited therapeutic management of infectious diseases caused by viruses, such as influenza and SARS-CoV-2, the medicinal use of essential oils obtained from Eucalyptus trees has emerged as an antiviral alternative, either as a complement to the treatment of symptoms caused by infection or to exert effects on possible pharmacological targets of viruses. This review gathers and discusses the main findings on the emerging role and effectiveness of Eucalyptus essential oil as an antiviral agent. Studies have shown that Eucalyptus essential oil and its major monoterpenes have enormous potential for preventing and treating infectious diseases caused by viruses. The main molecular mechanisms involved in the antiviral activity are direct inactivation, that is, by the direct binding of monoterpenes with free viruses, particularly with viral proteins involved in the entry and penetration of the host cell, thus avoiding viral infection. Furthermore, this review addresses the coadministration of essential oil and available vaccines to increase protection against different viruses, in addition to the use of essential oil as a complementary treatment of symptoms caused by viruses, where Eucalyptus essential oil exerts anti-inflammatory, mucolytic, and spasmolytic effects in the attenuation of inflammatory responses caused by viruses, in particular respiratory diseases.
