Abstract:

Purple coneflower, Echinacea sp. (Asteraceae), is a herbaceous perennial native to North America. Within the past decade, extensive research has been conducted to confirm echinacea's immunostimulatory, antiviral, and antibacterial benefits to humans. E. angustifolia, E. purpurea, and E. pallida are the primary species grown and studied for the herbal industry. However, there are other species and cultivars that may produce higher yields in biomass and chemical quality. The objective for this study is to evaluate the differences in biomass and phenolic content of five cultivars of E. purpurea and five species of Echinacea under Kentucky growing conditions. Differences in biomass (dry weight) of Echinacea species and cultivars harvested after the first year of growth was determined. There was a significant difference in total dry weight between E. purpurea cultivars. E. purpurea `Bright Star' and `Clio' produced significantly greater total dry weight compared to all other cultivars. There was no significant difference in root or flower biomass between cultivars. Biomass production differed between Echinacea species for root, vegetative, and flower parts. The total biomass of E. purpurea and E. tennesseensis was significantly higher compared to other species. E. pallida and E. paradoxa were not significantly different from E. purpurea in root biomass, even though both species produced less above-ground growth. E. tennesseensis produced 45% to 105% more flowers compared to other species. Differences in phenolic content between species and cultivars will also be presented.

Abstract:

Purple Coneflower [Echinacea sp. (Asteracea)] is of great value to the horticultural, pharmaceutical, and herbal industry. More research is needed to determine cultural practices that will produce a plant high in biomass and phenolic content, the chemical used for testing the quality of the harvested plant on a percent basis of roots, flowers and vegetative parts. The objective of this experiment is to determine if biomass and phenolic content of Echinacea purpurea and E. purpurea `Magnus' is influenced by fertilization after flower bud removal and vegetative pruning. The second objective of this study is to form an evaluation of the differences in biomass and phenolic content of five cultivars of E. purpurea and five species of Echinacea. Biomass and phenolic content will be evaluated to determine if exposing these plants to various treatments increases the quality of the plant over 1 and 2 years of growth. Differences in dry weights of Echinacea species and cultivars harvested after the first year of growth was determined. There was a significant difference in total dry weight between E. purpurea cultivars. Echinacea purpurea `Bright Star' and `Clio' significantly produced the most total dry weight compared to all other cultivars. There was no significant difference in root or flower biomass between cultivars. Biomass of Echinacea species was significantly different in root, vegetaive and flower parts. The total biomass of E. purpurea and E. tennesseensis was significantly higher compared to other species. Echinacea pallida and E. paradoxa were not significantly different from E. purpurea in root biomass, even though both species were small in above ground growth. Echinacea tennesseensis significantly produced 45% to 105% more flowers compared to other species. Differences in phenolic content between species and cultivars will also be presented.

Abstract:

Fresh Echinacea purpurea plant is a rich source of caffeic acid derivatives, which actively participate in the regulation of immune function. Herein, we describe a novel process for the production of fresh Echinacea purpurea juice rich in caffeic acid derivatives. This novel process includes steam heating (100°C, 15 min) before squeezing the juice to increase the recovery of caffeic acid derivatives from the flower or leaf by 1.5 to 3.7 fold. The recovery was further enhanced by 11–20% using ultrasonication at 500 W for 30 min. The flower, leaf, and root juice of Echinacea purpurea could be preserved for 4 weeks (4°C) or 6 months (−18°C) following ultra-high-pressure pasteurization (300 MPa, 15 min). Under these conditions, more than 90% of active cichoric acid was retained. Furthermore, the frozen-stored Echinacea purpurea juice exhibited similar or better immunoenhancement properties when measured by organ index, ear swelling, and carbon clearance test in mice compared with that of the positive control group (P < 0.05). Our results suggest that a combination of steam, ultrasound, and ultra-high-pressure treatment could serve as a superior process for the preparation of functional Echinacea purpurea juice.

Abstract:

We aimed to investigate the effects of Calendula officinalis and Echinacea purpurea extracts in terms of growth parameters, antibacterial activity and phenolic profile in tomato infected by Clavibacter michiganensis subsp. michiganensis (CmmT7). A significant difference was observed in E. purpura extract, indicating the highest effects on plant height (27.25 cm), fresh plant weight (28.45 cm), root length (24.42 cm), and root weight (6.74 g) (p<0.05). Moreover, Calendula officinalis and Echinacea purpurea extracts showed significant inhibitory activity against CmmT7 (p<0.05). Among phenolic compounds, the only chlorogenic acid amounts were varied in the tomato seedlings leaves with C. officinalis extract (K3) + CmmT7, E. purpurea extract (E3) + CmmT7 and CmmT7 (p<0.01). Moreover, chlorogenic acid amount was approximately 9 times higher than in CmmT7-treated leaves when compared to control. The results showed that application of the extracts of these plants had a significant influence on bacterial canker and growth parameters.

Abstract:

The results of many years of field research on the effect of stocking density of different types of Echinacea spp. on its productivity are discussed. It was found that when the Echinacea purpurea crops were thickened, the collected raw material had a high percentage (more than 50%) of stems, which negatively affected its quality. An increase in the density of Echinacea pallida crops has less effect on the formation of generative shoots. Long-term research has revealed patterns that determine the productivity of Echinacea spp. at different planting densities. This made it possible to calculate and recommend for production the density of plants at which the optimal yield of the agrocenosis will be achieved: for Echinacea purpurea – 100-110 thousand/ha, and for Echinacea pallida – 120-140 thousand/ha.

Abstract:

Biological Effects of Echinacea Purpurea on Human Blood CellsThe aim of this study was to investigate radioprotective properties of Echinacea purpurea tablets in vivo. We analysed lymphocyte chromosome aberrations (CA), micronuclei (MN), apoptosis of leukocytes and haematological parameters in a group of radiation workers who were identified as carrying dicentric chromosomes in their lymphocytes. All radiation workers were taking two 275 mg Echinacea tablets b.i.d., according to a pharmacist's recommendation. All parameters were analysed before and after the two-week treatment. At the end of the treatment lymphocyte CA frequency dropped significantly, and the number of apoptotic cells increased. The inverse lymphocyte-to-granulocyte ratio at the beginning of the study changed to normal at its end. In conclusion, biological effects observed after administration of Echinacea purpurea preparation suggest that it may be beneficial for the prevention of adverse health effects in workers exposed to ionising radiation.

Abstract:

ZusammenfassungDie drei Sonnenhutarten Echinacea angustifolia, E. pallida und E. purpurea werden als Ausgangsmaterial für die Produktion phytotherapeutischer und homöopathischer Zubereitungen genutzt, welche als unspezifische Immunstimulanzien Einsatz finden. Dabei sind vermutlich sowohl nieder- als auch hochmolekulare Inhaltsstoffe an der Wirkung beteiligt. Aus den verschiedenen Pflanzen und Pflanzenteilen entstehen durch Anwendung unterschiedlicher Herstellungsmethoden aufgrund der Vorgaben der Arzneibücher Zubereitungen, die erhebliche Unterschiede in ihrer stofflichen Zusammensetzung erwarten lassen. In den vorliegenden Untersuchungen wurden daher verschiedene Echinacea-haltige Zubereitungen hinsichtlich des Vorkommens von Kaffeesäurederivaten, Alkamiden, Polysacchariden und Proteoglykanen analytisch charakterisiert und verglichen.Erwartungsgemäß zeigte sich, dass sich homöopathische Urtinkturen bzw. alkoholische Extrakte sowohl hinsichtlich der hochmolekularen Inhaltsstoffe (Polysaccharide, Proteoglykane) als auch bei den polaren und lipophilen niedermolekularen Inhaltsstoffen von Echinacea-purpurea-Presssaftzubereitungen deutlich unterscheiden und sie daher nicht als äquivalent angesehen werden können. Auch zwischen den homöopathischen Urtinkturen der einzelnen Arten existieren Unterschiede und selbst innerhalb der Echinacea-purpurea-Presssaftzubereitungen konnten, je nach Herstellungsart, verschiedene Inhaltsstoffmuster detektiert werden. Bei der Bewertung von Wirksamkeit und Unbedenklichkeit von Echinacea-Zubereitungen sollten diese Unterschiede in Zukunft mehr berücksichtigt werden.

Abstract:

Purple coneflower, Echinacea purpurea (L.) Moench, is an important phytomedicinal species, producing phenolics and alkamides which have medicinal properties. This study examined the contribution of arbuscular mycorrhizal (AM) colonization on the physiology and biochemistry of E. purpurea, alone or in combination with jasmonic acid (JA), and over time. It was hypothesized that AM colonization enhances growth, nitrogen assimilation and secondary metabolism in E. purpurea. It was also hypothesized that JA application alone, or in combination with AM colonization, and growth time increases the phytochemical content. To verify these hypotheses, three greenhouse experiments were performed with E. purpurea, with or without AM fungus, Glomus intraradices Schenck & Smith, and harvested after (1) 13 weeks of growth; (2) 13 weeks and JA treatment; and (3) five different growth periods starting from week four to fifteen. The overall results indicated that AM colonization significantly increased the mass of shoots and roots, the concentration of proteins in roots and most of the phenolics. Results also suggested that the effects of AM colonization and/or JA application are similar on the induction of phenolics. Furthermore, time was a main factor on the enhancement of the phytochemical content, of the alkamides found to be dominant in roots, and phenolics in shoots. Optimizing the growth by AM colonization represents an organic method of enhancing E. purpurea yield and phytochemical content.

Abstract:

Echinacea purpurea is consumed as a natural health product around the world. Due to the genus’ ethnobotanical relevance, the phytochemistry of Echinacea has been extensively studied, revealing a variety of bioactive metabolites including caffeic acid derivatives and alkylamides. Whereas seasonal trends in root chemistry have been established, trends in other plant parts are relatively understudied. Similarly, few studies have evaluated the effects of organic plant growth substances in field trials. With increased demand for organic products, industry is looking for alternative ways to optimize yields and medicinal properties. For this thesis, my first objective was to quantify the concentrations of E. purpurea’s secondary metabolites across organic treatments throughout the plant’s first growth year to determine optimal harvesting time and conditions in all parts of the plant. The second objective was to determine how seasonal variations affect its potential bioactivity through inhibition of Pseudomonas aeruginosa. Plants were grown in field plots treated with four different organic treatments: water (control), high cytokinin, low cytokinin, and fish oils; samples were collected biweekly from May-September. Dried plants were separated into major plant parts and were extracted exhaustively in 70% EtOH. Using high-pressure liquid chromatography (HPLC), concentrations of alkylamides and select caffeic acid derivatives were quantified in all samples and compared across plant part, developmental stage, and organic fertilizers. It was determined that while there were no major differences between treatments, phytochemical concentrations changed throughout the season in all plant parts; revealing that aerial parts of the plant also bioactive secondary metabolites and should not be excluded from future studies. Following this study, an MIC50 assay was used to test these extracts against P. aeruginosa PA14. It was noted that seasonality effects of phytochemistry were not consistent with bioactivity and that there were no significant differences between extract and carrier control. While the antibiotic activity of root extracts varied seasonally, the flower extract exhibited the most consistent antibiotic potential. The results presented in this thesis will not only aid in industry practices and yield optimization but, through filling knowledge gaps on seasonality and organic treatments in field trials, will increase the understanding of E. purpurea’s chemistry and related bioactivity, with implications on both the medicinal properties and eco-physiology of the species.

Vaistiniai augalai šiuolaikinėje medicinoje turi labai didelę reikšmę. Šiuo metu Lietuvoje – tradicinėje ir liaudies medicinoje naudojama apie 460 augalų rūšių. Rausvažiedė ežiuolė yra vienas iš populiariausių vaistinių augalų. Iš jos pagaminti vaistai vartojami odos, onkologinių ir peršalimo ligų gydymui. Vaistinei žaliavai naudojamos įvairios rausvažiedės ežiuolės dalys: lapai, žiedai, stiebai, šaknys ir t.t. Nuimta vaistinė augalinė žaliava yra labai drėgna. Susidaro ypač palanki terpė mikroorganizmams vystytis. Todėl vaistinės augalinės žaliavos paruošimui dažniausiai naudojamas džiovinimas. Džiovinimo būdai didžia dalimi nulemia vaistinės augalinės žaliavos kokybę. Tyrimų tikslas – ištirti ir palyginti džiūvimo sąlygų įtaką rausvažiedės ežiuolės žolės ir skirtingų jos dalių drėgmės mainams su aplinka. Nustatyta, kad standžios augalo morfologinės dalys lemia stabilesnę ir poringesnę vaistinės augalinės žaliavos sampilo struktūrą, todėl džiovinant rausvažiedės ežiuolės žiedus ir ypač smulkintus stiebus bei žolę susiformuoja palankesnės džiūvimui sąlygos nei, pavyzdžiui, skintų lapų sampile.
Medicinal plants are of great importance in modern medicine. Currently, Lithuania - traditional and folk medicine used for about 460 species of plants. Echinacea purpurea is one of the most popular medicinal plants. From these plants made drugs are used to treat skin diseases, oncological diseases and cold diseases. Various parts of Echinacea purpurea an used for medicinal materials: leaves, flowers, stems, roots, etc. Been harvested herbal ingredients are very moist. There is a particularly favorable environment for the development of microorganisms. Therefore, the preparation of medicinal plant raw materials commonly used in drying. Drying methods are largely determined by the quality of raw materials. Purposes of the study - to investigate and compare the drying conditions on Echinacea purpurea herbs and different parts of moisture exchange with the environment. It was found that the rigid parts of the plant determines the morphological stability and more porous medicinal plant raw materials layer structure, therefore drying purple cone flowers, and especially the chopped stems and grass formed favorable drying conditions than cutted leaves layer.

Abstract:

This thesis describes the in vivo evaluation of orally administered extracts of Echinacea species, and fractions obtained from Echinacea purpurea for specific immunostimulatory function induced in Balb/c mice by immunization with microbial vaccines. Two vaccines were used for this purpose in this study. The first vaccine used consisted of whole-cell formalin-killed Salmonella typhimurium vaccine, which is known to induce production of specific antibodies but no delayed-type hypersensitivity response considered as an indicator of the cell-mediated immune response. The second vaccine was a commercial acellular pertussis vaccine (DTaP) consisting of inactivated diphtheria and tetanus toxoids and native or inactivated virulence factors of Bordetella pertussis (the etiological agent of whooping cough) which is known to induce a humoral immune response but with controversial reports about performance in the induction of cell-mediated immunity. Both vaccines were administered intraperitoneally, whereas the herbal extracts and fractions were administered by oral gavage. The phytochemical profile of the ethanolic extracts of Echinacea purpurea, Echinacea pallida, Echinacea angustifolia and one commercial product "Echinacea Triplex" and three fractions prepared from Echinacea purpurea, namely polysaccharides, phenolics and alkylamides, was determined by thin-layer chromatography, high-performance liquid chromatography and/or by chemical analytical techniques. Statistically significant increases in specific anti-Salmonella typhimurium serum antibody were obtained for the Echinacea purpurea, Echinacea angustifolia and Echinacea Triplex [Trade Mark] treatment groups, and also for groups receiving treatment with fractions obtained from Echinacea purpurea, namely, polysaccharide, alkylamide and phenolic fractions. Statistically significant increases in the anti-B pertussis serum antibodies were also obtained in the young Echinacea Triplex [Trade Mark] group vaccinated with the DTaP vaccine. Significant enhancement of serum interleukin-12 titres was observed in the Echinacea Triplex [Trade Mark] as well as the phenolic fraction treatment groups which were vaccinated with killed Salmonella typhimurium vaccine. Of the groups vaccinated with the DTaP vaccine, only Echinacea Triplex [Trade Mark] displayed statistically significant increases in mean interleukin-12 titre compared to the placebo in both young and old groups, however Echinacea purpurea, and Echinacea angustifolia both displayed significant increases in mean interleukin-12 titre in the young treatment mice. Increases in interferon-gamma levels in mice orally dosed with phenolic, polysaccharide or alkylamide fractions of Echinacea purpurea and vaccinated with the killed Salmonella typhimurium vaccine were also observed, however these need to be repeated for confirmation, and statistical analysis.

1. INTRODUCTION 1.1. Work actuality In recent years the number of males with urination disorders mostly induced by prostate pathology has significantly increased [Gas et al., 1998; Khan, Khan et al., 2005; Amaral, Coeli et al., 2004]. Benign prostate hyperplasia (BPH) affects males at a much younger age making them complain of urination disorders of different types and intensity. It is quite a common pathology among males (which is) conditioned by life style and nutrition [Saga & Sugimura, 2004; Shabbir & Mumtaz, 2004; Cambell, 2005]. Clinical symptoms of BPH are not restricted only to urination complaints. With an increase of age of males, the balance of androgens and estrogens undergoes changes in the male organism, affecting the power of libido. According to C.M.Porth, 2005, two theories related to senility have been created, trying to explain biological processes occurring with age: The first theory is related to the so called genetically programmed changes. This theory affirms that changes brought on by aging, are genetically predetermined. Another theory is called the stochastic theory which says that all changes are of accidental nature, i.e. the body undergoes accidental changes. There is one more theory, the so-called neuroendocrinic theory of senility. This theory involves three basic factors of the process of aging: 1) facilitated degradation of hormones, 2) decreased synthesis and secretion of hormones, 3) diminished sensitivity of “target” receptors to...

Abstract:

La fabrication d’un médicament sous forme de comprimés à base d'une plante fraîche reste actuellement encore un véritable enjeu et ce, à cause de la variabilité qui peut exister dans les différents lots d'extraits de plantes ainsi qu’à la limite imposée par les techniques de fabrication de comprimés existantes actuellement. Différents problèmes rencontrés avec la formulation actuelle de ce type de comprimés ont été observés tels que : les propriétés physiques du comprimé (très faible dureté des comprimés et temps de désagrégation assez long), goût désagréable, grande variabilité (variabilité de l'extrait sec) et mauvaise stabilité de la substance médicamenteuse. Des observations antérieures ont indiqué que la stabilité de la substance médicamenteuse dans les comprimés d'Echinacea purpurea ainsi que le goût peuvent être améliorés en la mélangeant avec de la bêta-cyclodextrine (β-CD). Dans la thèse de doctorat, une formulation actuelle commercialisée de comprimés d’Echinacea purpurea a été réalisée par la technique de la granulation par voie humide, avec un mélangeur à cisaillement élevé. Dans la formulation, presque la totalité de l'excipient (lactose monohydraté) est mouillé par le concentré d'Echinacea purpurea. Afin de réduire la quantité d'excipients à granuler et à sécher et d’obtenir un produit avec moins cher des couts de matériaux premières, un procédé de granulation classique a été proposé où seulement une fraction de la quantité totale de charge (cellulose microcristalline (MCC)) est utilisée pour la granulation et le séchage; le reste de la charge (sorbitol) est ajouté après la granulation. Ce granulat peut servir de matériau de base des différents comprimés. Dans les différentes expérimentations réalisées, la teinture d’Echinacea purpurea a été utilisée comme modèle pour l'optimisation de la fabrication des comprimés à base de plantes. L'objectif de la thèse était par conséquent de développer une nouvelle formulation de comprimés d’Echinacea purpurea en utilisant un procédé de granulation classique. Avec une meilleure maîtrise de la granulation humide (WGP) et son influence sur les propriétés physiques des comprimés, ceux-ci doivent être optimisés du point du vue de la stabilité de l'ingrédient actif qui se présente sous forme solide (alkylamides) et des propriétés physiques des comprimés, en particulier le taux de dissolution et les propriétés physiques des comprimés
One current formulation of Echinacea tablets which is examined in the present thesis is to produce tablets in a wet granulation process (WGP) with a high shear mixer. During the manufacturing, almost the whole amount of the excipient (lactose monohydrate) is wetted by Echinacea purpurea concentrate. In order to reduce the amount of excipients being granulated and dried by a basis granulate method was proposed where only a fraction of the total amount of filler (Microcrystalline cellulose, MCC) is used for granulation and drying, the rest of the filler (sorbitol) is added after granulation. This granulate can serve as basis material for different tablets.Purpose: in the PhD thesis, tablets containing Echinacea purpurea tincture were used as a model for the optimization of herbal tablets. The aim of the dissertation was to develop a new Echinaforce formulation based on the “Basis Granulate” technology. With deeper understanding of the WGP and its influence on the physical tablet properties, the new Echinaforce tablets should be optimized in term of cost of goods, taste of tablets, stability of the active ingredient in solid forms (alkylamides) and the physical tablet properties of Echinaforce tablets, especially the dissolution rate and the compaction properties of the final tablet

Echinacea purpurea (L.) Moench (family Asteraceae) herbal medicines and dietary supplements are traditionally used as immunostimulants in the treatment of inflammatory and viral diseases. Employed are roots and aerial parts. The main active compounds of Echinacea purpurea (L.) Moench are alkamides and polyacetylenes, caffeic acid derivatives, polysaccharides and glycoproteins. With regard to caffeic acid derivatives, several compounds have been identified from the hydrophilic fractions of Echinacea extracts, such as caftaric acid, chlorogenic acid, caffeic acid and cichoric acid. Cichoric acid is found to be the main phenolic compound in E. purpurea. From the caffeic acid derivatives, only cichoric acid has shown immunostimulatory properties, promoting phagocyte activity in vitro and in vivo. In addition, cichoric acid has antihyaluronidase activity, and has a protective effect on the free-radical-induced degradation of collagen. Cichoric acid has also shown antiviral activity and has recently been found to inhibit HIV-1 integrase and replication. Tasks of investigation: to prepare samples for phenolic acids analysis by supercritical fluid, soxhlet extractions and maceration methods and optimize SPE parameters. Evaluate amount of cichoric acid and compare it in different parts of plant by spectrophotometric method. Optimize HPLC analysis conditions and identify the main phenolic acids by HPLC. Compare amounts of phenolic acids between plant parts and extraction methods... [to full text]

Abstract:

As a potential bioremediation system for contaminated soils, I evaluated the use of an arbuscular mycorrhizal (AM) fungus, Glomus intraradices on roots and shoots uptake of polycyclic aromatic hydrocarbons (PAHs), alkyl PAHs, and toxic metals in Echinacea purpurea, in using a controlled 20-week greenhouse study and a complimentary 2-year field study. E. purpurea seeds were either inoculated with the mycorrhizal fungus (AM) or not inoculated (non-AM) and grown in soil provided by the National Capital Commission (NCC) that have known contamination. In the greenhouse study, AM inoculation increased the uptake of alkyl PAHs in the roots of E. purpurea. The AM inoculation showed no effect on root uptake of PAHs and toxic metals over the 20-week study period. However, when I calculated the uptake rates (k1) for PAHs between both treatments, the AM treated roots ha 10-fold higher k1 values than non-AM treated roots. The soil concentrations of PAHs were found to increase over time with AM inoculation, suggesting, that AM fungi are causing a solvent depletion through root uptake of minerals and carbon, which concentrates the more hydrophobic PAHs in soils. Alkyl PAHs and metals showed no change over time amongst any of the treatments. Assessing the performance of AM fungi on the uptake of contaminants under field conditions, only PAHs showed increased bioaccumulation in the shoots of E. purpurea with AM inoculation. Alkyl PAHs and metals in plant material were unaffected by the AM inoculation, but increased significantly from year 1 to year 2. The uptake rates among treatments were similar, with non-AM roots having slightly greater uptake. Soil concentrations of PAHs and alkyl PAHs were unaffected over the course of the experiment. Our control soil, however, showed significant increases in concentration from year 1 to year 2 with alkyl PAHs. These results quantified the influence of AM hyphae-mediated uptake of organic and inorganic contaminant transfer from soil to plants and the bioaccumulation kinetics for contaminants by E. purpurea that will be useful for environmental models and phytoremediation strategies.

Abstract:

Background: Echinacea possibly reduces the effectiveness of corticosteroids, commonly used by asthmatics and for treating viral induced wheeze, and can cause hypersensitivity reactions in susceptible individuals. Treatment of the common cold in children with Echinacea has only been investigated in one randomized, double blind, placebo controlled trial to examine the efficacy and safety of Echinacea purpurea in children with upper respiratory tract infections. This study aimed to investigate the effect Echinacea purpurea herbs in reducing symptoms of upper respiratory infection. Subjects and Method: This was meta-analysis and systematic review. The study was conducted by collecting published articles from PubMed, Science Direct, and Google Scholar databases. The study subject was adults with upper respiratory infection. Intervention was Echinecea purpurea herbs extract with comparison placebo. The study outcome was decreased symptoms of upper respiratory tract infection. The inclusion criteria were full text, using English language, and using randomized controlled trial. The collected articles were selected by PRISMA flow chart. The quantitative data were analyzed using Revman 5.3 Results: A meta-analysis using 6 studies from United States resulted high heterogeneity between experimental groups (I2= 98%; p<0.001), so it conducted by random effect model (REM). This study showed that provision of Echinecea purpurea herbs extract reduced symptoms of upper respiratory tract infection than placebo (Mean Difference= -0.56; 95% CI= -0.91 to -0.22; p= 0.001). Conclusion: Echinecea purpurea herbs extract reduced symptoms of upper respiratory tract infection than placebo. Keywords: Echinacea purpurea herbs extract, upper respirstory infection Correspondence: Riska Fajar Fatony. Masters Program in Public Health, Universitas Sebelas Maret. Jl. Ir.

Abstract:

Bunga kerucut ungu (Echinacea purpurea (L.) Moench) merupakan tanaman obat introduksi dari Amerika Utara yang belum banyak dibudidayakan di Indonesia. Budidaya E. purpurea dapat dikembangkan pada lahan salin mengingat semakin tingginya degradasi lahan. Tanaman pada cekaman salinitas melakukan perubahan morfologi akar dan fisiologi sebagai bentuk adaptasi. Penelitian ini bertujuan untuk mengetahui respon morfologi akar dan fisiologi E. purpurea pada cekaman salinitas CaCl2 yang berbeda. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) faktorial terdiri dari dua faktor dengan lima kali ulangan. Faktor pertama yaitu 3 aksesi E. purpurea (aksesi 1; aksesi 2; dan aksesi 3). Faktor kedua yaitu 4 level konsentrasi CaCl2 (0 ppm; 2.500 ppm; 5.000 ppm; dan 10.000 ppm). Parameter terbagi menjadi 2 yaitu morfologi dan fisiologi, morfologi meliputi panjang akar, volume akar dan rasio tajuk akar, fisiologi meliputi kandungan klorofil total dan aktivitas nitrat reduktase. Data dianalisis dengan analisis sidik ragam, analisis korelasi sederhana dan uji DMRT taraf 5%. Hasil penelitian menunjukkan bahwa semakin tinggi konsentrasi CaCl2 terjadi penurunan panjang akar, volume akar, kandungan klorofil total dan aktivitas nitrat reduktase tetapi meningkatkan rasio tajuk akar. Aksesi 2 merupakan aksesi yang toleran terhadap cekaman salinitas dengan menunjukkan hasil terbaik pada semua parameter.
