    The pharmacological properties of medicinal plants have been related to the presence of organic compounds, however elements are also known to have an important participation in the active compounds constitution process. In this study, instrumental neutron activation analysis (INAA) was applied to determine elements in leaves of Casearia obliqua medicinal plant collected at two different locations in the Atlantic Forest, Brazil, SP. Soil samples collected from where this plant was grown were also analyzed in order to verify if there is a correlation between the elements present in soils and plant leaves. Br, Ca, Cl, Co, Cr, Cs, Fe, K, La, Mn, Na, Rb, Sb, Sc and Zn were determined in C. obliqua leaves and the elements As, Ca, Ce, Eu, Fe, Hf, La, Lu, Nd, Rb, Sc, Sm, Tb, Th, U and Zn in soils. Soil samples collected from two different locations presented similar concentrations for most elements. Likewise, C. obliqua leaves collected from the two locations presented similar elemental contents. These results suggest that analysis of extracts from these leaf samples and the evaluation of their pharmacological activities should be carried out. Certified reference materials IAEA-Soil-7, USGS W-1, NIST 1573a Tomato Leaves and NIST 1515 Apple Leaves were analyzed and the quality of the obtained results was assured. (author)

    The use of medicinal plants in the treatment of diseases has increased significantly in the last years, as has research concerning chemical characterization of these plants. In this study, inorganic constituents were determined in leaves and in extracts from three medicinal plant species of the Casearia genus (C. sylvestris, C. decandra and C. obliqua) collected in distinct regions of the Atlantic Forest, SP. The elemental compositions of the soils in which these plants were grown were also determined. Traditionally, these plants are used due to their antiinflammatory, antiacid, antiseptic and cicatrizing properties. The antiulcer and the antitumor activities of the Casearia genus and its capacity to neutralize snake and bee venoms, have also been scientifically confirmed. The analytical methodology used was neutron activation analysis. Long and short irradiation periods of the samples and the standards were carried out at IPEN's IEA-R1 nuclear research reactor. In the leaf K was found at the percentage levels, Ca, Cl, Mg and Na at mg g{sup -1} levels and the elements Br, Fe, Mn, Rb and Zn at the {mu}g g{sup -1} levels. As, Co, Cr, Cs, La, Sb, Sc and Se at the ng g{sup -1} levels. Results obtained in the extracts indicated that the same elements present in the leaves are also found in their extracts. The comparison between the inorganic composition of Casearia sylvestris leaves collected from three different regions of the Atlantic Forest showed that the elemental concentrations in the plants leaves varied depending on the place where they were grown. Different Casearia species cultivated in a same region presented similar elemental compositions. Based on these findings it can be concluded that the studies about the pharmacological effect of Casearia genus plants grown in different types of soil are of great importance. The quality of the obtained results was assured by the analyses of the certified reference materials NIST 1573a Tomato Leaves, NIST 1515 Apple

    Full Text Available Casearia sylvestris Swartz (Salicaceae has been used in traditional medicine and its leaf extracts have been exhibited important pharmacological activities. The species presents morphological, chemical and genetic variation. Two varieties are considered due external morphological differences: C. sylvestris var. sylvestris and var. lingua. There are difficulties in definition of these varieties. The objective of this work is to evaluate chemical and morpho-anatomical differences between C. sylvestris varieties that can be applied in their distinction for pharmaceutical or botanical purposes. Transverse and paradermic sections of leaves were prepared for morpho-anatomical, histochemical and quantitative microscopy (stomatal and palisade index analyses. Diterpene profiles of the specimens were obtained by HPLC-DAD and TLC. Morpho-anatomical analyses demonstrated significant differences between the varieties only in paradermic sections: var. sylvestris - polygonal epidermic cell walls and hypostomatic; var. lingua - rounded epidermic cell walls and amphistomatic. No differences were observed for stomatal index; palisade index was found 2.8 for var. lingua and 3.9 for var. sylvestris. Chromatographic analyses confirmed previous results demonstrating that diterpene profile in varieties differs, with predominance of these metabolites in var. sylvestris. In conclusion, this work indicates that chromatographic analysis besides morpho-anatomical analysis can be applied in distinction of C. sylvestris varieties.

    Full Text Available Folk uses and scientific investigations have highlighted the importance of Casearia sylvestris extracts and their relevant bioactive potential. The aim of this work was to review the pharmacological properties of C. sylvestris, emphasizing its anti-ulcer, anti-inflammatory, anti-ophidian and antitumor potentialities. Ethanolic extracts and essential oil of their leaves have antiulcerogenic activity and reduce gastric volume without altering the stomach pH, which corroborates their consumption on gastrointestinal disorders. Leaf water extracts show phospholipase A2 inhibitory activity that prevents damage effects on the muscular tissue after toxin inoculation. This antiphospholipasic action is probably related to the use as an anti-inflammatory, proposing a pharmacological blockage similar to that obtained with non-steroidal anti-inflammatory drugs on arachidonic acid and cyclooxygenase pathways. Bioguided-assay fractionations lead to the identification of secondary metabolites, especially the clerodane diterpenes casearins (A-X and casearvestrins (A-C, compounds with a remarkable cytotoxic and antitumor action. Therefore, the C. sylvestris shrub holds a known worldwide pharmacological arsenal by its extensive folk utilization, exciting searches for new molecules and a better comprehension about biological properties.Usos populares e pesquisas científicas têm destacado a importância dos extratos da planta Casearia sylvestris e seu grande potencial bioativo. Neste trabalho, objetiva-se revisar as propriedades farmacológicas de C. sylvestris, enfatizando sua potencialidade antiulcerogênica, antiinflamatória, antiofídica e antitumoral. O extrato etanólico e o óleo essencial das folhas possuem atividade antiulcerogênica promissora, diminuindo o volume gástrico sem alterar o pH estomacal, corroborando sua aplicação contra dores gastrointestinais.

    Full Text Available No Ocidente, o consumo de plantas medicinais vem aumentando substancialmente, onde cerca de 40% da população utiliza regularmente plantas medicinais e preparações fitoterápicas sob o rótulo de serem produtos inócuos ou seguros. Porém, na maioria das vezes, não há comprovação científica de suas propriedades farmacológicas e toxicológicas. O objetivo deste trabalho foi realizar um levantamento bibliográfico sobre as propriedades toxicológicas da Casearia sylvestris Swartz e coletar dados que fundamentem seu uso racional. Alguns estudos validam indicações terapêuticas clássicas da C. sylvestris como antidiarréico e no tratamento de ferimentos ofídicos, fundamentando seu uso empírico. Porém, poucos trabalhos relatam suas propriedades toxicológicas, havendo apenas abordagens limitadas em torno da Dose Letal 50% e da toxicidade aguda de seus constituintes. Até o presente momento, as pesquisas são insuficientes para garantir a segurança de preparações populares à base de C. sylvestris. Portanto, há necessidade de avaliar melhor seu perfil deletério, principalmente, no que diz respeito ao potencial tóxico de seus constituintes, assim como a sua capacidade lesiva sobre órgãos-alvos e sistemas orgânicos.

O presente estudo teve como objetivo avaliar a eficácia do tratamento tópico com soluções de Casearia sylvestris Sw. em lesões de pele experimentalmente induzidas em camundongos. Foram utilizados 15 animais aleatoriamente distribuídos em 3 grupos: GC (tratados com solução fisiológica, G1% (tratados com solução de guaçatonga a 1% e G10% tratados com solução de guaçatonga a 10%. As feridas foram avaliadas e mensuradas nos dias 1, 4, 6, 8 e 13 após a indução das lesões. Não foram observadas diferenças estatísticas entre os tratamentos, todavia, observou-se cicatrização completa das feridas no grupo G1% em um prazo menor que os demais, o que sugere que o tratamento com guaçatonga a 1% apresente maior tendência à promoção da cicatrização. Novos estudos avaliando os efeitos de diferentes concentrações da planta em uma população maior de animais são necessários para melhor entendimento dos efeitos da Casearia sylvestris Sw. sobre o processo de cicatrização.

    During the XVIII century, two Spanish scientific expeditions arrived here led, respectively, by the naturalist Martín Sessé and by the Italian mariner Alessandro Malaspina di Mulazzo, dependent from the Spanish Government. The members collected a rich scientific material, which was carried to Madrid in 1820. At the end of XVIII century, the Franciscan friar Juan Navarro depicted and described several Mexican medicinal plants in the fifth volume of his "American Garden". In the last years of the Colonial period, fundamental works of Humboldt and Bonpland, on the geographic distribution of the American plants, were published. At the end of the XIX century, the first researches on the Mexican medicinal botany were performed at the laboratory of the "Instituto Médico Nacional" under the leadership of doctor Fernando Altamirano, starting pharmacological studies in our country. During the first half of the XX century, trials of cardiovascular pharmacology were performed in the small laboratories of the cardiological unit at the General Hospital of Mexico, due to doctor Ignacio Chávez, initiative. Mexican botanical-pharmacological tradition remains alive and vigorous in the modern scientific institutes of the country.

    2006-01-01

    In recent years there has been a notable increase in the consumption of medicinal plants in Spanish society. This might be due to the fact that in some cases they have shown themselves to be efficient in treating certain pathologies and to the erroneous perception that these products are innocuous. Medicinal plants behave as authentic medicines since the chemical substances of which they are formed can have a biological activity in humans. For this reason, their joint administration with "conventional medicines" can produce variations in the magnitude of the effect. This type of interaction, just like those produced between two or more medicines, can produce pharmacokinetic mechanisms if they affect the processes of absorption, distribution, metabolism and excretion, or pharmacodynamic mechanisms if they affect the result of the pharmacological action. In the medical literature there are few articles and notifications of cases concerning the adverse effects and interactions that affect medicinal plants, which probably reflects an under-notification of these phenomena. If we add to this the lack of experimental data and controlled studies, perception of their prevalence is difficult or nearly impossible. This article sets out, in an order that will be explained later, the findings of an exhaustive review of the medical literature with the aim of making its existence known to the reader, without going into other considerations, such as the degree of evidence for example, which will be the subject of forthcoming articles.

    2015-07-01

    The aim of this review was to provide a comprehensive summary of medicinal plants used as antifertility agents in females throughout the world by various tribes and ethnic groups. We undertook an extensive bibliographic review by analyzing classical text books and peer reviewed papers, and further consulting well accepted worldwide scientific databases. We performed CENTRAL, Embase, and PubMed searches using terms such as "antifertility", "anti-implantation", "antiovulation", and "antispermatogenic" activity of plants. Plants, including their parts and extracts, that have traditionally been used to facilitate antifertility have been considered as antifertility agents. In this paper, various medicinal plants have been reviewed for thorough studies such as Polygonum hydropiper Linn, Citrus limonum, Piper nigrum Linn, Juniperis communis, Achyanthes aspera, Azadirachta indica, Tinospora cordifolia, and Barleria prionitis. Many of these medicinal plants appear to act through an antizygotic mechanism. This review clearly demonstrates that it is time to expand upon experimental studies to source new potential chemical constituents from medicinal plants; plant extracts and their active constituents should be further investigated for their mechanisms. This review creates a solid foundation upon which to further study the efficacy of plants that are both currently used by women as traditional antifertility medicines, but also could be efficacious as an antifertility agent with additional research and study.

    Natural preparations have been used for thousands of ages for a variety of purposes including as medicines, poisons, and psychotropic drugs. The largest grouped of preparations from living organisms are medicines, and historically these have come from plants. Quinine and aspirin are two examples of medicines which were extracted originally from plants. Mind-altering, or psychotropic, drugs come mostly from plants or fungi. In many traditional cultures, sickness and death are attributed to maligned spirits so that medicine and religion become inseparable. Uses of cohohba, snakeplant, coca, and peyote are discussed. The process by which new pharmaceuticals are discovered from natural products is described. The implications of an agreement between a major pharmaceutical company and a country in the tropics are discussed.

    The purpose of this study was to investigate the use of the artificial taste sensor in the evaluation of 11 medicinal plants and 10 Chinese medicines with bitter and/or astringent tastes, and to assess the possible application of the sensor in the evaluation of taste and quality control of medicinal products. Aqueous extracts of the six bitter medicinal plants could be classified into three types, and those of the five astringent medicinal plants into two types, on the basis of sensor output pattern profiles. These differences seem to derive from the different structures of the main components. In the principal component analysis of the taste sensor output of 10 Chinese medicines, a new measure developed, the 'Euclidean distance', defined as the distance between a control and the targeted substance on the principal component map. This measure offers a possibility for indicating the different tastes of Chinese medicines. Lastly, we confirmed that berberine adsorption on the surface of the artificial membrane of the taste sensor was of the Langmuir type. The berberine content in extracts of medicinal plants could be evaluated by the taste sensor, and it was shown to be possible to use the taste sensor for the quality control of medicinal plants.

    Full Text Available There are a number of medicinal combinations in the Iranian traditional medicine which are commonly used as tonic for liver. In this review, we have introduced some medicinal plants that are used mainly for the treatment of liver disorders in Iranian folk medicine, with focus on their hepatoprotective effects particularly against CC14 agent. In this study, online databases including Web of Science, PubMed, Scopus, and Science Direct were searched for papers published from January 1970 to December 2013. Search terms consisted of medicinal plants, traditional medicine, folk medicine, hepatoprotective, Iran, liver, therapeutic uses, compounds, antioxidant, CC14, anti-inflammatory, and antihepatotoxic, hepatitis, alone or in combination. Allium hirtifolium Boiss., Apium graveolens L., Cynara scolymus, Berberis vulgaris L., Calendula officinalis, Nigella sativa L., Taraxacum officinale, Tragopogon porrifolius, Prangos ferulacea L., Allium sativum, Marrubium vulgare, Ammi majus L., Citrullus lanatus Thunb, Agrimonia eupatoria L. and Prunus armeniaca L. are some of the medicinal plants that have been used for the treatment of liver disorders in Iranian folk medicine. Out of several leads obtained from plants containing potential hepatoprotective agents, silymarin, β-sitosterol, betalain, neoandrographolide, phyllanthin, andrographolide, curcumin, picroside, hypophyllanthin, kutkoside, and glycyrrhizin have been demonstrated to have potent hepatoprotective properties. Despite encouraging data on possibility of new discoveries in the near future, the evidence on treating viral hepatitis or other chronic liver diseases by herbal medications is not adequate.

    Full Text Available Numerous plants are used as snakebite antidotes in Brazilian folk medicine, including Casearia sylvestris Swartz, popularly known as guaçatonga. In this study, we examined the action of a hydroalcoholic extract from C. sylvestris on the neuromuscular blockade caused by bothropstoxin-I (BthTX-I, a myotoxin from Bothrops jararacussu venom, in mouse isolated phrenic nerve-diaphragm (PND preparations. Aqueous (8 and 12 mg/ml, n=4 and 5, respectively and hydroalcoholic (12 mg/ml, n=12 extracts of the leaves of C. sylvestris caused facilitation in PND preparations followed by partial neuromuscular blockade. BthTX-I (20 µg/ml, n=4 caused 50% paralysis after 65±15 min (mean ± S.E.M. Preincubation (30 min at 37° C of BthTX-I (20 µg/ml, n=4 with a concentration of the hydroalcoholic extract (4 mg/ml that had no neuromuscular activity, such as the control (n=5, prevented the neuromuscular blockade caused by the toxin. This protection may be mediated by compounds such as flavonoids and phenols identified by thin-layer chromatography and colorimetric assays.

    In recent decades, the polysaccharides from the medicinal plants have attracted a lot of attention due to their significant bioactivities, such as anti-tumor activity, antioxidant activity, anticoagulant activity, antidiabetic activity, radioprotection effect, anti-viral activity, hypolipidemic and immunomodulatory activities, which make them suitable for medicinal applications. Previous studies have also shown that medicinal plant polysaccharides are non-toxic and show no side effects. Based on these encouraging observations, most researches have been focusing on the isolation and identification of polysaccharides, as well as their bioactivities. A large number of bioactive polysaccharides with different structural features and biological effects from medicinal plants have been purified and characterized. This review provides a comprehensive summary of the most recent developments in physiochemical, structural features and biological activities of bioactive polysaccharides from a number of important medicinal plants, such as polysaccharides from Astragalus membranaceus, Dendrobium plants, Bupleurum, Cactus fruits, Acanthopanax senticosus, Angelica sinensis (Oliv.) Diels, Aloe barbadensis Miller, and Dimocarpus longan Lour. Moreover, the paper has also been focused on the applications of bioactive polysaccharides for medicinal applications. Recent studies have provided evidence that polysaccharides from medicinal plants can play a vital role in bioactivities. The contents and data will serve as a useful reference material for further investigation, production, and application of these polysaccharides in functional foods and therapeutic agents.

    For many years attempts are made to develop efficient methods for transformation of medicinal plants via Agrobacterium tumefaciens. It is a soil bacteria which possess a natural ability to infect plants in places of injures which results in arise of cancerous growths (crown gall). This is possible thanks a transfer of fragment of Ti plasmid into plant cells and stable integration with a plant genome. Efficiency of medicinal plant transformation depends on many factors for example: Agrobacterium strain, methods and procedures of transformation as well as on plant species, type and age of the explants and regeneration conditions. The main goal of plant transformation is to increase the amount of naturally occurring bioactive compounds and the production of biopharmaceuticals. Genetic plant transformation via bacteria of the genus Agrobacterium is a complex process which requires detailed analysis of incorporated transgene expression and occurs only in the case when the plant cell acquires the ability to regenerate. In many cases, the regeneration efficiency observed in medicinal plants are inefficient after applied transformation procedures. To date there have been attempts of genetic transformation by using A. tumefaciens of medicinal plants belonging to the families: Apocynaceae, Araceae, Araliaceae, Asphodelaceae, Asteraceae, Begoniaceae, Crassulaceae, Fabaceae, Lamiaceae, Linaceae, Papaveraceae, Plantaginaceae, Scrophulariaceae and Solanaceae.

    Full Text Available The term ‘Antiviral agents’ has been defined in very broad terms as substances other than a virus or virus containing vaccine or specific antibody which can produce either a protective or therapeutic effect to the clear detectable advantage of the virus infected host. The herbal medicine has a long traditional use and the major advantage over other medicines is their wide therapeutic window with rare side effects. There are some disadvantages of synthetic drugs like narrow therapeutic window and more importantly the various adverse side effects which occur quite frequently. Due to these disadvantages and other limitations, there is an increasing trend in the field of research for discovering new and noble drugs based on various herbal formulations. This review attempts to address the importance of developing therapeutic herbal formulations from various medicinal plants using the knowledge based on traditional system of medicines, the Ayurveda. Although natural products have been used by civilization since ancient times, only in recent decades has there been growing research into alternative therapies and the therapeutics use of natural products, especially those derived from plants. Plants synthesize and preserve a variety of biochemical products, many of which are extractable and used for various scientific investigations. Therefore, medicinal plants proved to be a major resort for the treatment of diseases and sicknesses by traditional healers in many societies.

    Stefanie Bressan Waller

    Full Text Available ABSTRACT Cases of sporotrichosis in humans and animals without satisfactory clinical response have increased, a warning sign of strains resistant to conventional antifungal agents. The urgent search for alternative therapies was an incentive for research on medicinal plants with anti-Sporothrix spp. properties. A bibliographic survey was performed based on scientific papers about in vitro and in vivo antifungal activity of essential oils and extracts of plants in differents solvents against the fungal of the Sporothrix schenckii complex. The study methodology consisted of a literature review in Google Scholar, Science Direct, Pubmed, Bireme and Springer link with papers from 1986 to 2015. We found 141 species of plants that were investigated, of which 100 species were concentrated in 39 botanical families that had confirmed anti-Sporothrix activity. Combretaceae, Asteraceae and Lamiaceae represented the botanical families with the greatest number of plants species with antifungal potential, using different methodologies. However, there are few studies with medicinal plants in experimental infection in animals that prove their activity in the treatment of sporotrichosis. It reinforces the need for further research related to standardization of in vitro methodologies and in vivo studies related to safety and to toxicity potential of these plants with anti-Sporothrix spp. activity.

    In this review, we evaluate the reports published between 1993 and 2011 that address the heavy metal accumulation in 88 medicinal plant species. We compare the safe limits for heavy metals set by governmental agencies vs. the levels at which such metals actually exist in selected medicinal plants. We also evaluate the uses and effectiveness of medicinal plants in health care, and assess the hazards of medicinal plant uses, in view of the growing worldwide use of medicinal plants. From our extensive review of the literature, we discovered that a maximum permissible level (MPL) of Pb is exceeded in 21 plant medicine species, Cd in 44 species, and Hg in 10 species. Vetiveria zizanioides a potential candidate species for the treatment of cardiovascular diseases absorb a wide range of heavy metals from metal-contaminated soils. We believe that this species is the single most impressive example of a potentially hazardous medicinal plant. Based on our review, we endorse the hypothesis that heavy metal accumulation by medicinal plants is mainly caused by extraction of soluble metals from contaminated soil, sediments and air. One continuing problem in protecting consumers of plant-based medicines is that permissible levels of all heavy metals in herbal medicine have not yet been standardized by regulating governmental entities. Moreover, there are few limit tests that exist for heavy metal content of medicinal plants, or permissible limits for essential dietary minerals, in most medicinal plants. The dearth of such limits hamstrings development of medicinal plant research and delays the release of either new or improved versions of medicinal plants or their components. In the present review, we emphasize that medicinal plants are often subjected to heavy metal contamination and that the levels at which these heavy metals sometimes occur exceeds permissible levels for some species. Therefore, collecting medicinal plants from areas that are, or may be, contaminated should be

    Silphium was both a spice and a medicinal plant. It was regarded as "one of the most precious gifts of Nature to man" (Pliny), and was one of the main sources of revenue contributing to Cyrenaica's wealth. It was so critical to the Cyrenian economy that most of their coins bore a picture of the plant. But, by the time of Nero, the plant had become extinct, probably as a result of overgrazing and overcropping. The botanical identification of silphium is dificult, but the plant was an Umbellifera and most closely resembled Ferula tingitana. Hippocrates, Celsus, Galen and Oribasius recommended it for quartan fever, but it was also said to be useful for many other diseases.

    Full Text Available Burns are known as one of the most common forms of injury with devastating consequences. Despite the discovery of several antiseptics, burn wound healing has still remained a challenge to modern medicine. Herbal products seem to possess moderate efficacy with no or less toxicity and are less expensive compared to synthetic drugs. Burn is a well-known disorder in Iranian Traditional Medicine (ITM. Iranian physicians have divided burns into various types based on the cause and recommended treatment for each type. According to ITM references, herbal therapy was the major treatment prescribed by Iranian physicians for burns. In the present study, seven ancient Iranian medical texts were screened for the herbs with burn healing effects along with their applied dosage forms. The medicinal herbs were listed and scored based on the frequency of their repetition. Moreover, the best scientific name that was suitable for each plant as well as surveying modern studies about their biological effects has been carried out. In our investigation eighteen plants with seven topical application categories have been obtained as the most frequent herbs for burn healing in ITM. Modern studies have revealed that these plants have shown some biological activities such as anti-inflammatory, antimicrobial and antioxidant effects which might establish the relationship between the mentioned activities and burn wound healing property. This list can provide a suitable resource for future researches in the field of burn treatment.

    Medicinal plants are increasingly recognized worldwide as an alternative source of efficacious and inexpensive medications to synthetic chemo-therapeutic compound. Rapid declining wild stocks of medicinal plants accompanied by adulteration and species substitutions reduce their efficacy, quality and safety. Consequently, the low accessibility to and non-affordability of orthodox medicine costs by rural dwellers to be healthy and economically productive further threaten their life expectancy. Finding comprehensive information on medicinal plants of conservation concern at a global level has been difficult. This has created a gap between computing technologies' promises and expectations in the healing process under complementary and alternative medicine. This paper presents the design and implementation of a Multimedia-based Medicinal Plants Sustainability Management System addressing these concerns. Medicinal plants' details for designing the system were collected through semi-structured interviews and databas...

    Full Text Available Various forms of cancer are rising all over the world, requiring newer therapy. The quest of anticancer drugs both from natural and synthetic sources is the demand of time. In this study, fourteen extracts of different parts of eleven Bangladeshi medicinal plants which have been traditionally used for the treatment of different types of carcinoma, tumor, leprosy, and diseases associated with cancer were evaluated for their cytotoxicity for the first time. Extraction was conceded using methanol. Phytochemical groups like reducing sugars, tannins, saponins, steroids, gums, flavonoids, and alkaloids were tested using standard chromogenic reagents. Plants were evaluated for cytotoxicity by brine shrimp lethality bioassay using Artemia salina comparing with standard anticancer drug vincristine sulphate. All the extracts showed potent to moderate cytotoxicity ranging from LC50 2 to 115 µg/mL. The highest toxicity was shown by Hygrophila spinosa seeds (LC50=2.93 µg/mL and the lowest by Litsea glutinosa leaves (LC50=114.71 µg/mL in comparison with standard vincristine sulphate (LC50=2.04 µg/mL. Among the plants, the plants traditionally used in different cancer and microbial treatments showed highest cytotoxicity. The results support their ethnomedicinal uses and require advanced investigation to elucidate responsible compounds as well as their mode of action.

    Full Text Available Traditional medicines are used by about 60% of the world’s population. These are used for primary health care, not only in rural areas of developing nations but they are also used in the developed countries where modern medicine are pre dominantly used. In the western world the use of medicinal herbs is continuously growing, approximately 40% of the population is using herbs for medical illness due to increased incidences of adverse effects of allopathic medicine. There are about 45000 plant species in India, Eastern Himalayas, Western Ghats and Andman and Nicobar Islands are the hot spot for medicinal plants. Officially documented plants with medicinal potential are 3000 but traditional practitioner use more than 6000. Seventy percent of the population in the rural India is dependent on the ayurvedic system of medicine. Most of the drugs used in modern medicine and ancient Indian medicinal system are of plant origin. Beside plants many minerals, salts and animal products are used in Ayurvedic medicines. Homoeopathy originated in west, German physician Samuel Hanemann was the father of homoeopathy (1796, the homeopathic remedies are prepared by successive dilution followed by shaking forcefully. Homoeopathy uses animal, plant, mineral, and synthetic substances in its remedies. Arsenicum album (arsenic oxide, Natrum muriaticum (sodium chloride, opium (plant, and thyroidinum (thyroid hormone are some of the homoeopathic medicines extracted from different sources.

    Ecological stoichiometry is a study of the balance of biological system's energy and the balance of multiple chemical elements. It focuses on the relationship of the element ratio in ecological processes. In this paper, the concept and main theoretical basis of ecological stoichiometry were introduced, and the status of stoichiometry in medicinal plant resources was reviewed. According to the recent development of ecological stoichiometry, the future directions of ecological stoichiometry of medicinal plants could be the study of the relationship between stoichiometric characteristic and growth and secondary metabolism of medicinal plants, and the influence of biotic (or abiotic) factors on the stoichiometric characteristic of medicinal plants.

    Full Text Available In this paper, we propose a methodology for color and edge histogram based medicinal plants image retrieval. The medicinal plants are divided into herbs, shrubs and trees. The medicinal plants are used in ayurvedic medicines. Manual identification of medicinal plants requires a priori knowledge. Automatic recognition of medicinal plants is useful. We have considered medicinal plant species, such as Papaya, Neem, Tulasi and Aloevera are considered for identification and retrieval. The color histograms are obtained in RGB, HSV and YCbCr color spaces. The number of valleys and peaks in the color histograms are used as features. But, these features alone are not helpful in discriminating plant images, since majority plant images are green in color. We have used edge and edge direction histograms in the work to get edges in the stem and leafy parts. Finally, these features are used in retrieval of medicinal plant images. Absolute distance, Euclidean distance and mean square error, similarity distance measures are deployed in the work. The results show an average retrieval efficiency of 94% and 98% for edge and edge direction features respectively.

    Liping Li

    Full Text Available With both a full collection of native vascular plant distributions and a full checklist of source plants of the Chinese Materia Medica (CMM, the Uygur Medicine (UM, and the Kazak Medicine (KM for the Xinjiang region, we defined medicinal plant: vascular plant ratios (simplified as medicinal plant ratios hereafter as the value of medicinal plant richness divided by vascular plant richness. We aimed to find whether the ratios are constant or change in different environments, which environmental variables determine medicinal plant ratios, and whether the ratios are more influenced by human or by natural environments. Finally, suggestions for medicinal plant conservation were addressed. We found that (1 medicinal plant ratios were not constant, and they were high in the Tarim Basin which was largely covered by desert, while they were relatively low in mountainous areas, especially in the Tianshan Mountains where the general species richness was high; (2 medicinal plant ratios were not significantly influenced by human activities, indicated by human population density distributions, but they were highly correlated with plant species richness and climate, i.e. ratios decreased with plant species richness and MAP, and were related quadratically with MAT; (3 CMM ratio and UM ratio were more influenced by plant richness than by climate, while KM ratio was more influenced by climate. We concluded that the percentages of plants used as medicines were not influenced by distances from human settlements, but were determined by species richness or climate. We suggest that (1, in general, the medicinal plant ratio could be a complementary indicator for medicinal plant conservation planning and (2, for the region of Xinjiang, not only high diversity areas, but also some extreme environments should be considered as compensation for a better protection of medicinal plants.

    Medicinal plants are widely used as home remedies and raw materials for the pharmaceutical industries. Herbal remedies are used in the prevention, treatment and cure of disorders and diseases since ancient times. However, use of medicinal herbs may not meet the requirements of quality, safety and efficacy. During harvesting, handling, storage and distribution, medicinal plants are subjected to contamination by various fungi, which may be responsible for spoilage and production of mycotoxins. The increasing consumption of medicinal plants has made their use a public health problem due to the lack of effective surveillance of the use, efficacy, toxicity and quality of these natural products. The increase in use of medicinal plants may lead to an increase in the intake of mycotoxins therefore contamination of medicinal plants with mycotoxins can contribute to adverse human health problems and therefore represents a special hazard. Numerous natural occurrences of mycotoxins in medicinal plants and traditional herbal medicines have been reported from various countries including Spain, China, Germany, India, Turkey and from Middle East as well. This review discusses the important mycotoxins and their natural occurrences in medicinal plants and their products.

    2006-06-01

    Full Text Available Abstract Background The use of plants for healing by any cultural group is integrally related to local concepts of the nature of disease, the nature of plants, and the world view of the culture. The physical and chemical properties of the plants themselves also bear on their selection by people for medicines, as does the array of plants available for people to choose from. I examine use of medicinal plants from a "biobehavioral" perspective to illuminate cultural selection of plants used for medicine by the Gitksan of northwestern British Columbia, Canada. Methods Consultant consensus, "intercultural consensus", independent use of the same plants by other cultural groups, and phytochemistry and bioassay results from the literature, were employed in analysis of probable empirical efficacy of plant uses. Results 70% of 37 Gitksan medicinal plants were used similarly by other cultures where direct diffusion is not known to have occurred; eleven plants, including the eight most frequently mentioned medicinal plants, also show active phytochemicals or bioassays indicating probable physiologically based therapeutic effects. Conclusion Analysis of intercultural consensus revealed that the majority of cultures in the British Columbia region within the plant ranges use the same plants, or closely related species, in similar ways. The rigor of this analysis is effected by the lack of consistent data on all taxa of interest for all cultures within the region.

    2013-01-01

    Full Text Available There is a growing interest in natural plant-based remedies as a source for commercial products. Around 80% of the South African population use traditional medicines to meet their primary health care needs; however, only a few South African medicinal plants have been exploited to their full potential in terms of commercialization. The opportunity for bioprospecting of plant compounds for novel pharmaceuticals remains largely untapped. Certain renowned medicinal plants of international acclaim including buchu and rooibos are currently contributing to local enterprise; however, other exciting opportunities exist for commonly used plants which have not yet reached the international arena. This paper focuses on the key research and development contributions of 10 commercially important medicinal plants of South Africa. Traditional uses, scientific validation, commercialisation developments, as well as both potential opportunities and setbacks are discussed.

    Increase in cases of various cancers has encouraged the researchers to discover novel, more effective drugs from plant sources. This study is a review of medicinal plants in Iran with already investigated anticancer effects on various cell lines. Thirty-six medicinal plants alongside their products with anticancer effects as well as the most important plant compounds responsible for the plants' anticancer effect were introduced. Phenolic and alkaloid compounds were demonstrated to have anticancer effects on various cancers in most studies. The plants and their active compounds exerted anticancer effects by removing free radicals and antioxidant effects, cell cycle arrest, induction of apoptosis, and inhibition of angiogenesis. The investigated plants in Iran contain the compounds that are able to contribute effectively to fighting cancer cells. Therefore, the extract and active compounds of the medicinal plants introduced in this review article could open a way to conduct clinical trials on cancer and greatly help researchers and pharmacists develop new anticancer drugs.

  16. The microbiome of medicinal plants: diversity and importance for plant growth, quality and health

    2013-12-01

    Full Text Available Past medicinal plant research primarily focused on bioactive phytochemicals, however the focus is currently shifting due to the recognition that a significant number of phytotherapeutic compounds are actually produced by associated microbes or through interaction with their host. Medicinal plants provide an enormous bioresource of potential use in modern medicine and agriculture, yet their microbiome is largely unknown. The objective of this review is i to introduce novel insights into the plant microbiome with a focus on medicinal plants, ii to provide details about plant- and microbe-derived ingredients of medicinal plants, and iii to discuss possibilities for plant growth promotion and plant protection for commercial cultivation of medicinal plants. In addition, we also present a case study performed both to analyse the microbiome of three medicinal plants (Matricaria chamomilla L., Calendula officinalis L. and Solanum distichum Schumach. and Thonn. cultivated on organically managed Egyptian desert farm and to develop biological control strategies. The soil microbiome of the desert ecosystem was comprised of a high abundance of Gram-positive bacteria of prime importance for pathogen suppression under arid soil conditions. For all three plants, we observed a clearly plant-specific selection of the microbes as well as highly specific diazotrophic communities that overall identify plant species as important drivers in structural and functional diversity. Lastly, native Bacillus spec. div. strains were able to promote plant growth and elevate the plants’ flavonoid production. These results underline the numerous links between the plant-associated microbiome and the plant metabolome.

    2014-01-01

    Full Text Available The use of medicinal plants in Brazil is widespread and is supported by public policies; it has the objective of providing the population with safe and effective herbal medicines of adequate quality. An action in these policies is to develop medicinal plant monographs to gather published information and decide which medicinal plants should be financed by the Brazilian government and distributed by the public health system. Currently, the monographs published worldwide do not present unified information regarding medicinal plants, and generally, they do not cover enough requirements for herbal medicine registration. The aim of this study is to develop a monograph model with standardized information not only about botany, agronomy, quality control, safety, and efficacy but also about relating regulatory aspects that support herbal medicine regulation. The development of standardized monographs favors the fast authorization and distribution of herbal medicines in the public system. The model also points out the lacking studies that should be carried out to supplement the necessary regulatory information of medicinal plants.

    Over the last years, great interest has arisen concerning plant stilbenes, especially resveratrol, which has a whole spectrum of positive biological activities. In this study, we investigated the presence of resveratrol monomers (trans- and cis- form) and naturally occurring derivatives of trans-resveratrol (piceid, astringin and isorhapontin) in phenolic extracts of twenty medicinal plants traditionally used in Croatian folk medicine. The investigated compounds were present in the samples, in free form or as glucosides, and the highest share was found in immortelle, common yarrow and Lamiaceae plants. The obtained results indicate that biological activity of selected medicinal plants can be related to the presence of this valuable group of phytochemicals.

    As part of the ICBG program Bioactive Agents from Dryland Biodiversity of Latin America, the present investigation was undertaken to explore the possible antimycobacterial potential of compounds derived from selected Mexican medicinal plants. Bioassay-guided fractionation of the crude extracts of Rumex hymenosepalus (Polygonaceae), Larrea divaricata (Zygophyllaceae), Phoradendron robinsonii (Loranthaceae) and Amphipteryngium adstringens (Julianiaceae) led to the isolation of several antimycobacterial compounds. Four stilbenoids, two flavan-3-ols and three anthraquinones were isolated from R. hymenosepalus. Two flavonols and nordihydroguaiaretic acid were obtained from L. divaricata. Sakuranetin was the antimycobacterial agent isolated from P. robinsonii. Two known triterpenoids and the novel natural product 3-dodecyl-1,8-dihydroxy-2-naphthoic acid were obtained from A. adstringens. In general, the isolates were identified by spectral means. The antimycobacterial activity of the secondary compounds isolated from the analysed species, as well as that of nine pure compounds previously isolated in our laboratories, was investigated; the MIC values ranged from 16 to 128 microg mL-1. Among the tested compounds, the glycolipids, sesquiterpenoids and triterpenoids showed the best antimycobacterial activity. The antimycobacterial property of the glycolipids is reported for the first time. Although the tested compounds showed moderate antimycobacterial activity, their presence in the analysed species provides the rationale for their traditional use in the treatment of tuberculosis.

  3. Are medicinal plants polluted with phthalates?

    2013-05-29

    Phthalic acid esters (PAEs) have been employed in polymer materials as a plasticizer to form them more flexible, adhesive, and soluble. These compounds are mainly used in paints, varnishes, personal cares, cosmetics, paper coatings, and adhesives even in bottled waters, shampoo, body deodorant, hairspray, and gels. Phthalates are able to possess remarkable toxic variations depending on their structures. So far, Di-(2-EthylHexyl) Phthalate DEHP and Di-n- Butyl Phthalate DBP have been found to cause reproductive and developmental toxicities. The U.S. Environmental Protection Agency (EPA) classified DEHP as probable human carcinogen. To the best of our knowledge, phthalates showed diverse toxicity profiles according to their structures in the liver, kidneys, thyroid, and testes, which are involved in general toxicity. Furthermore, they are introduced as hormonally-active agents, because they can interfere with the endocrine system in human. Incidence of developmental abnormalities (like skeletal malformations and cleft palate, and undescended testes, lowering testes weight and anogenital distance) seems increasing via high exposure to phthalate metabolites. Although, increasing the capacity for phthalate free plasticizer productions is the first step to restrict the distribution of these toxic manmade compounds, finding the new ways for phthalate absorption from the soil in agricultural fields may have benefits. Also, evaluation and examination of diverse sources of medicinal and food plants to determine the level of phthalate accumulation in their organs are extremely recommended to avoid creating toxicity particularly in reproductive systems.

    The rapid growth rate of human population, along with the public health crisis encountered in many regions, particularly in developing world, creates an urgent need for the discovery of alternative drugs. Because medicinal plants are not distributed randomly across lineages, it has been suggested that phylogeny along with traditional knowledge of plant uses can guide the identification of new medicinally useful plants. In this study, we combined different statistical approaches to test for phylogenetic signal in 33 categories of plant uses in South Africa. Depending on the null models considered, we found evidence for signal in up to 45% of plant use categories, indicating the need for multiple tests combination to maximize the chance of discovering new medicinal plants when applying a phylogenetic comparative approach. Furthermore, although there was no signal in the diversity of medicinal uses-that is, total number of medicinal uses recorded for each plant-our results indicate that taxa that are evolutionarily closely related have significantly more uses than those that are evolutionarily isolated. Our study therefore provides additional support to the body of the literature that advocates for the inclusion of phylogeny in bioscreening medicinal flora for the discovery of alternative medicines.

    Full Text Available The benefit and transaction cost flow which people earn economically and socially from wild medicinal plant harvesting are addressed in this study. The objectives of this study are three aspects: defining how many users are involved in utilization of medicinal plant raw materials (MPRM, how users describing their perception and motivation and describing benefit and transaction cost which influence users to harvest the plants. Results showed that utilization of medicinal plants in Java is still widely used as commercial products then medical services. There are 41 stakeholders who involved in this study and the highest motivation and perception in production and industrial clusters are economic interest. But stakeholder's perception and motivation in traditional healthcare cluster is social interest. The different motivation and perception in both clusters causing stakeholder who are work in traditional healthcare lack of market information, but they are important if the government will improve the traditional medicine. Recommendation of this study is that medicinal plants need further research and product development which can help to expand the medicinal plant culture area in the natural forest. By this reason, government should develop good political will to increase the medicinal plant resources for public healthcare.

    Two main research questions are framing this investigation: (1) the main taxa of the medicinal importance value altered the Showbak forest stand and species composition? (2) The most safe species and what are the toxic ones (unsafe). These two research questions are the vital ones to draw a clear image about the wild medicinal plants of this investigated area of Showbak region in Jordan. 79 wild medicinal plant species were investigated in this study which are used in traditional medication for the treatment of various diseases. Most of the locals interviewed dealt with well-known safe medicinal plants such as Aaronsohnia factorovskyi Warb. et Eig., Achillea santolina L., Adiantum capillus-veneris L., Artemisia herba-alba L., Ceratonia siliqua L., Clematis recta L., Herniaria hirsuta L., Malva neglecta Wallr., Rosmarinus officinalis L., Ruta chalepensis L., Salvia triloba L., Sarcopoterium spinosa (L.) Spach., Thymbra capitata (L.) Hof, and Urginea maritima Barker. Many of the wild medicinal plants investigated were toxic and needed to be practiced by practitioners and herbalists rather than the local healers. These plants include Calotropis procera Willd R.Br., Citrullus colocynthis (L.) Sch., Datura stramonium L., Digitalis purpurea L., Ecballium elaterium (L.) A.Rich., Euphorbia helioscopia L., Euphorbia tinctoria Boiss., Glaucium corniculatum (L.) Curt., Hyoscyamus aureus L., Mandragora officinarum L., Nerium oleander L., Ricinus communis L., Solanum nigrum L., Withania somnifera (L.) Dunel. The conservation of medicinal plants and natural resources is becoming increasingly important, so this research is trying to collect information from local population concerning the use of medicinal plants in Showbak; identify the most important specie; determine the relative importance value of the species and calculate the informant consensus factor (ICF) for the medicinal plants. Obtaining results is relied on the interviewee's personal information and the medicinal use

    Results and Conclusion: Among the screened medicinal plants, Zingiber officinale and Solanum torvum were found to have GABA. The percentage of GABA present in Z. officinale and S. torvum were found to be 0.0114% and 0.0119%, respectively. The present work confirmed that among the selected CNS active medicinal plants, only two plants contain GABA. We found a negative correlation with plant having CNS activity and accumulation of GABA. The GABA shunt is a conserved pathway in eukaryotes and prokaryotes but, although the role of GABA as a neurotransmitter in mammals is clearly established, its role in plants is still vague.

    In Mexico about 4,000 plant species have some medicinal use. The aim of this work was to evaluate the antimicrobial activity of six Mexican medicinal plants against fungi and Gram-positive and Gram-negative bacteria. Methanolic extracts were prepared from the Mexican medicinal plants Amphypteringium adstrigens, Castella tortuosa, Coutarea latiflora, Ibervillea sonorae, Jatropha cuneata, and Selaginella lepidophylla. The antibacterial and antifungal activities of the plants were determined by the broth microdilution method and the radial growth inhibition assay, respectively. All Mexican plants tested showed antimicrobial activity. Among the six plant extracts analyzed, J. cuneata showed the highest growth-inhibitory activity against fungi, Gram-positive and Gram-negative bacteria (J. cuneata > A. adstrigens > C. latiflora > C. tortuosa > I. sonorae approximately S. lepidophylla). Shigella flexneri and Staphylococcus aureus were the most susceptible bacteria to plant extracts. Complete inhibition of S. flexneri growth was observed with J. cuneata methanolic extract at 90 microg/mL. This plant extract also showed the strongest antifungal activity against Fusarium verticillioides and Aspergillus niger. Our data suggest that the medicinal plants tested have important antimicrobial properties. This is the first report describing the antimicrobial activities of several of the Mexican medicinal plants used in this study.

    In order to have standardized formulations, the chemical constituents from plants and their parts are required to be uniform both qualitatively and quantitatively. Furthermore, an ever increasing demand of uniform medicinal plants based medicines warrants their mass cloning through plant tissue culture strategy. A good number of medicinal plants have been reported to regenerate in vitro from their various parts, but a critical evaluation of such reports reveals that only a few complete medicinal plants have been regenerated and still fewer have actually been grown in soil, while their micropropagation on a mass scale has rarely been achieved, particularly in those medicinal plants where conventional propagation is inadequate, like, the mass clonal propagation of Dioscorea floribunda leading to its successful field trials. Such facts make it imperative to document the factual position of micropropagation of medicinal plants bringing out the advancements made along with the short falls, in this important area. The present review deals with the futuristic view on the said subject restricted to higher plants.

    Full Text Available The holistic concept of Xhosa and Zulu traditional medicine and some differences from Western orthodox practice are briefly outlined. The transmission of herbal knowledge within various social groups is outlined. The background, training and some procedures followed by five of the informants are discussed. Plant characteristics that may be seen, felt, smelled or tasted are considered as possible determinants of usage. The form of plant parts accounts for some usage in the more magically orientated medicines whereas colour, texture or the production of froth may signal the presence of medicinally active components such as tannin, mucilage and saponin. The role of plants producing a milky latex is discussed. Vesicant or irritant properties are utilized in septic or inflammatory conditions. Aromatic plants are used for respiratory or digestive disorders and pungent-smelling plants are used in the treatment of catarrh and some stress-related disorders. Bitter or sour- tasting plants may be used as an aid to digestion or serve a deterrent function. Parallel usage of some related plants in African and European herbal practice indicates that appropriate usage may be widely determined by easily discerned plant characteristics. Two herbal medicinal recipes recorded by the author and a list of medicinal plants collected in Transkei are presented.

    Many complementary and alternatives medicines are offered to patients with cancer. Among them, herbal medicines have a substantial place. These plants are mainly used to reduce adverse effects of anticancer treatments and for specific anticancer properties. Our review shows that only few clinical data support medicinal plants effectiveness in cancer patients. Arguments rely mainly on usual indications and pharmacological data for minimization of treatments toxicity while for the anticancer properties, on epidemiological and preclinical data. To inform and counsel patients and people around, healthcare professionals need to evaluate benefit-risk balance on evidence-based information. Because the medical decision should be shared with the patient, his beliefs and preferences have to be considered. When no adverse effect or drug interaction is associated with herbal medicine, we state that their use is acceptable. This paper discuss of potential risk and benefit of the most used medicinal plants by cancer patients.

    Full Text Available Traditional home gardens have been described as man-managed ecosystems with high energy subsidy, complex structure, and multiple functions. These have been reported as treasure trove of a rich biodiversity of plant species including medicinal plants used for traditional home remedies of various ailments. A review of research work on the status of medicinal plants in traditional rural home gardens is presented with the objective to explore them as potential preservation site for medicinal plants. From the available literature it can be ascertained that these traditional rural home gardens can be a suitable site for conservation, propagation, and expansion of medicinal plants that form the backbone of the traditional medicine system and are fast dwindling due to over exploitation and development pattern. Widely reported presence in rural home gardens of medicinal plant species, such as, Adhatoda vasica, Nees., Aloe vera, Mill., Asparagus racemosus, Willd., Chlorophytum tuberosum, Baker., Curcuma angustifolia, Roxb., Dioscorea bulbifera, L., Dioscorea hispida, Dennst., Emblica officinalis, Gaertn., Gymnema sylvestre, Br., Rauwolfia serpentina, Benth., Terminalia arjuna, (Roxb. Wight. and Arn., Tinospora cordifolia, Miers., that are considered endangered is a further confirmation of this belief that traditional rural home gardens can be a good conservation site for domestication and conservation of these plant species.

    Full Text Available Medicinal plants are increasingly recognized worldwide as an alternative source of efficacious and inexpensive medications to synthetic chemo-therapeutic compound. Rapid declining wild stocks of medicinal plants accompanied by adulteration and species substitutions reduce their efficacy, quality and safety. Consequently, the low accessibility to and non-affordability of orthodox medicine costs by rural dwellers to be healthy and economically productive further threaten their life expectancy. Finding comprehensive information on medicinal plants of conservation concern at a global level has been difficult. This has created a gap between computing technologies' promises and expectations in the healing process under complementary and alternative medicine. This paper presents the design and implementation of a Multimedia-based Medicinal Plants Sustainability Management System addressing these concerns. Medicinal plants' details for designing the system were collected through semi-structured interviews and databases. Unified Modelling Language, Microsoft-Visual-Studio.Net, C#3.0, Microsoft-Jet-Engine4.0, MySQL, Loquendo Multilingual Text-to-Speech Software, YouTube, and VLC Media Player were used.

    The use of medicinal plants as a fundamental component of the African traditional healthcare system is perhaps the oldest and the most assorted of all therapeutic systems. In many parts of rural Africa, traditional healers prescribing medicinal plants are the most easily accessible and affordable health resource available to the local community and at times the only therapy that subsists. Nonetheless, there is still a paucity of updated comprehensive compilation of promising medicinal plants from the African continent. The major focus of the present review is to provide an updated overview of 10 promising medicinal plants from the African biodiversity which have short- as well as long-term potential to be developed as future phytopharmaceuticals to treat and/or manage panoply of infectious and chronic conditions. In this endeavour, key scientific databases have been probed to investigate trends in the rapidly increasing number of scientific publications on African traditional medicinal plants. Within the framework of enhancing the significance of traditional African medicinal plants, aspects such as traditional use, phytochemical profile, in vitro, in vivo, and clinical studies and also future challenges pertaining to the use of these plants have been explored.

    Medicinal plants are traditionally used in folk medicine as natural healing remedies with therapeutic effects such as prevention of cardiovascular diseases, inflammation disorders, or reducing the risk of cancer. In addition, pharmacological industry utilizes medicinal plants due to the presence of active chemical substances as agents for drug synthesis. They are valuable also for food and cosmetic industry as additives, due to their preservative effects because of the presence of antioxidants and antimicrobial constituents. To commonly used medicinal plants with antioxidant activity known worldwide belong plants from several families, especially Lamiaceae (rosemary, sage, oregano, marjoram, basil, thyme, mints, balm), Apiaceae (cumin, fennel, caraway), and Zingiberaceae (turmeric, ginger). The antioxidant properties of medicinal plants depend on the plant, its variety, environmental conditions, climatic and seasonal variations, geographical regions of growth, degree of ripeness, growing practices, and many other factors such as postharvest treatment and processing. In addition, composition and concentration of present antioxidants, such as phenolic compounds, are related to antioxidant effect. For appropriate determination of antioxidant capacity, the extraction technique, its conditions, solvent used, and particular assay methodology are important.

    Recent scientific studies have proven the importance of trace elements on human health. The main food supplies are plants and animals, which are significant sources of these minerals. Studies on determining mineral compositions of herbs, spices and some other crops have increased all over the world. Published works revealed that spices, herbs and medicinal plants should be consumed to obtain beneficial trace elements. Selenium (Se), one of the most vital trace elements, has a significant role in human diet acting as a preventative agent against some serious illnesses. Despite numerous scientific works on mineral compositions of medicinal and aromatic plants, investigations of selenium content in these foods could not be successfully studied until recently due to the lack of suitable analytical methods for selenium analysis. Thus, publications on selenium concentrations of foods are recent. In this regard, selenium contents of some medicinal and aromatic plants commonly used as spices, herbal teas and traditional medicines in Turkey were studied in the present research. Selenium contents of the most used parts of these plants were analyzed by ICP-OES (Varian Vista-Pro, Australia). Of the analyzed 26 medicinal and aromatic plants, the highest Se concentration (1133 microg kg-1) was found in sweet basil (Ocimum basilicum L.) and the lowest in sumac (Rhus coriaria L.) fruits (11 microg kg(-1)).

    Full Text Available Abstract Background A large number of people in both developing and developed countries rely on medicinal plant products to maintain their health or treat illnesses. Available evidence suggests that medicinal plant consumption will remain stable or increase in the short to medium term. Knowledge on what factors determine medicinal plant consumption is, however, scattered across many disciplines, impeding, for example, systematic consideration of plant-based traditional medicine in national health care systems. The aim of the paper is to develop a conceptual framework for understanding medicinal plant consumption dynamics. Consumption is employed in the economic sense: use of medicinal plants by consumers or in the production of other goods. Methods PubMed and Web of Knowledge (formerly Web of Science were searched using a set of medicinal plant key terms (folk/peasant/rural/traditional/ethno/indigenous/CAM/herbal/botanical/phytotherapy; each search terms was combined with terms related to medicinal plant consumption dynamics (medicinal plants/health care/preference/trade/treatment seeking behavior/domestication/sustainability/conservation/urban/migration/climate change/policy/production systems. To eliminate studies not directly focused on medicinal plant consumption, searches were limited by a number of terms (chemistry/clinical/in vitro/antibacterial/dose/molecular/trial/efficacy/antimicrobial/alkaloid/bioactive/inhibit/antibody/purification/antioxidant/DNA/rat/aqueous. A total of 1940 references were identified; manual screening for relevance reduced this to 645 relevant documents. As the conceptual framework emerged inductively, additional targeted literature searches were undertaken on specific factors and link, bringing the final number of references to 737. Results The paper first defines the four main groups of medicinal plant users (1. Hunter-gatherers, 2. Farmers and pastoralists, 3. Urban and peri-urban people, 4. Entrepreneurs and

    Full Text Available Problem statement: World Wide Web (WWW consisting large volume of information related with medicinal plants. However health care recommendation with Indian Medicinal Plants becomes complicated because valuable Information about medicinal resources as plants is scattered, in text form and unstructured. Search engines are not quite efficient and require excessive manual processing. Therefore search becomes difficult for the ordinary users to find the medicinal uses of herbal plants from the web. And another problem is that the domain experts could not able to map the medicinal uses of herbal plants with the existing standardized medical terms. Mapping the existing ontology introduces the problem of finding the similarity between the terms and relationships. Finding the solution to perform automatic mapping is another major challenge to be solved. Approach: To address these issues we developed a Knowledge framework for the Indian Medicinal Plants (KIMP. Knowledge framework includes the ontology creation, user interface for querying the system. Jena is used to build semantic web applications with the ontology representation of Resource Description Framework (RDF and Web Ontology Language (OWL. SPARQL Protocol and RDF Query Language (SPARQL is used to retrieve various query patterns. Automated mapping is achieved by considering lexical and edge based relatedness. Results: The user interface is demonstrated for five thousand concepts, which gives the related information from Wikipedia web page in three languages. Mapping recommendation by the lexical similarity Jaccard algorithm gives 27% and Jaro Winkler algorithm gives 60%. Edge based relationship using WuPalmer algorithm gives 93% mapping recommendation. These are analyzed and compared with our algorithm based on WuPalmer gives more specific mapping results than WuPalmer with 71%. Conclusion: Thus it possible to find the specific resultant web page based on the user requirement in three different

    Pyrrolizidine alkaloids (PAs) are mutagenic, carcinogenic, pneumotoxic, teratogenic and fetotoxic. Plants containing PAs commonly poison livestock in many countries, including the USA and Canada. In some regions of the world PA-producing plants sometimes grow in grain crops and items of food made with PA contaminated grain, such as bread baked using contaminated flour, have been, and continue to be, responsible for large incidents of acute, often fatal human poisoning. Herbal medicines and food supplements containing PAs are also recognized as a significant cause of human poisoning and it is desirable that such medications are identified and subjected to strict regulation. In this review we consider the PAs known to be, or likely to be, present in both the traditionally used medicinal plants of North America and also medicinal plants that have been introduced from other countries and are being recommended and used as phytopharmaceuticals in the USA and Canada.

    Acquired immunodeficiency syndrome patients face great socio-economic difficulties in obtaining treatment. There is an urgent need for new, safe, and cheap anti-HIV agents. Traditional medicinal plants are a valuable source of novel anti-HIV agents and may offer alternatives to expensive medicines in future. Various medicinal plants or plant-derived natural products have shown strong anti-HIV activity and are under various stages of clinical development in different parts of the world. The present study was directed towards assessment of anti-HIV activity of various extracts prepared from Indian medicinal plants. The plants were chosen on the basis of similarity of chemical constituents with reported anti-HIV compounds or on the basis of their traditional usage as immunomodulators. Different extracts were prepared by Soxhlet extraction and liquid-liquid partitioning. Ninety-two extracts were prepared from 23 plants. Anti-HIV activity was measured in a human CD4+ T-cell line, CEM-GFP cells infected with HIV-1NL4.3. Nine extracts of 8 different plants significantly reduced viral production in CEM-GFP cells infected with HIV-1NL4.3. Aegle marmelos, Argemone mexicana, Asparagus racemosus, Coleus forskohlii, and Rubia cordifolia demonstrated promising anti-HIV potential and were investigated for their active principles.

In this paper, we report the results of 10 field surveys of Salvia medicinal plants collected in 17 provinces including detailed information on their local names, growing environment, distribution and therapeutic effects. We also summarize the results of research on the materia medica, phytochemistry and pharmacology of some of the important Salvia medicinal plants. Our study reveals that 35 Salvia plants have been used in TCM in different regions of China, including 20 species used as Danshen to treat heart diseases, and 15 species used to treat a range of other conditions including gynecological diseases, muscular or skeletal problems, hepatitis, urological diseases, and mouth and eye conditions. It is clear that some species of Salvia L. possess significant pharmacological activity in the context of ethnopharmacological knowledge, especially in the treatment of heart disease. Further studies of the phytochemistry and pharmacology of Salvia species will no doubt improve their medical utilization and contribute to the development of new natural drugs.

    Full Text Available Scientific research regarding medicinal plants started first in Cluj, where the Research Station for Medicinal Plants was first organized in Europe (1904. Research in this field was continued after 1930 by the staff of the Agronomy Researh Institute of Romania (ICAR. Beginning with 1975 the national research programme regarding the medicinal plants is coordinated by the Research Station for Medicinal and Aromatic Plants -SCPMA - Fundulea. Studies are performed in the experimental fields and in the laboratories of this institute and different other research stations and universities in Romania. Beginning with 1979, a new specialized periodical - Herba Romanica - published the main results in the field. At present there are cultivated in Romania about 60 different medicinal and aromatic plant species. Recently a tendency emerged toward the concentration of the production to the most suitable regions and the specialization of different farms for the cultivation of a more restricted number of species. In the second part of the paper the species studied and/or cultivated in the experimental fields of the Agronomy Institute Cluj-Napoca are presented with a chronological list of papers published by the stuff in the period 1975-1984.

    Medicinal plants are an important element of indigenous medical systems in Mexico. These resources are usually regarded as part of a culture's traditional knowledge. This study examines the use of medicinal plants in four indigenous groups of Mexican Indians, Maya, Nahua, Zapotec and - for comparative purposes - Mixe. With the first three the methodology was similar, making a direct comparison of the results possible. In these studies, the relative importance of a medicinal plant within a culture is documented using a quantitative method. For the analysis the uses were grouped into 9-10 categories of indigenous uses. This report compares these data and uses the concept of informant consensus originally developed by Trotter and Logan for analysis. This indicates how homogenous the ethnobotanical information is. Generally the factor is high for gastrointestinal illnesses and for culture bound syndromes. While the species used by the 3 indigenous groups vary, the data indicate that there exist well-defined criteria specific for each culture which lead to the selection of a plant as a medicine. A large number of species are used for gastrointestinal illnesses by two or more of the indigenous groups. At least in this case, the multiple transfer of species and their uses within Mexico seems to be an important reason for the widespread use of a species. Medicinal plants in other categories (e.g. skin diseases) are usually known only in one culture and seem to be part of its traditional knowledge.

    2016-06-01

    Plants have emerged as commercially relevant production systems for pharmaceutical and nonpharmaceutical products. Currently, the commercially available nonpharmaceutical products outnumber the medical products of plant molecular farming, reflecting the shorter development times and lower regulatory burden of the former. Nonpharmaceutical products benefit more from the low costs and greater scalability of plant production systems without incurring the high costs associated with downstream processing and purification of pharmaceuticals. In this review, we explore the areas where plant-based manufacturing can make the greatest impact, focusing on commercialized products such as antibodies, enzymes, and growth factors that are used as research-grade or diagnostic reagents, cosmetic ingredients, and biosensors or biocatalysts. An outlook is provided on high-volume, low-margin proteins such as industrial enzymes that can be applied as crude extracts or unprocessed plant tissues in the feed, biofuel, and papermaking industries.

    Full Text Available Many developing countries including Cameroon have mortality patterns that reflect high levels of infectious diseases and the risk of death during pregnancy and childbirth, in addition to cancers, cardiovascular diseases and chronic respiratory diseases that account for most deaths in the developed world. Several medicinal plants are used traditionally for their treatment. In this review, plants used in Cameroonian traditional medicine with evidence for the activities of their crude extracts and/or derived products have been discussed. A considerable number of plant extracts and isolated compounds possess significant antimicrobial, antiparasitic including anti-malarial, anti-proliferative, anti-inflammatory, anti-diabetes, and antioxidant effects. Most of the biologically active compounds belong to terpenoids, phenolics and alkaloids. Terpenoids from Cameroonian plants showed best activities as anti-parasitic, but rather poor antimicrobial effects. The best antimicrobial, anti-proliferative and antioxidant compounds were phenolics. In conclusion, many medicinal plants traditionally used in Cameroon to treat various ailments displayed good activities in vitro. This explains the endeavor of Cameroonian research institutes in drug discovery from indigenous medicinal plants. However, much work is still to be done to standardize methodologies and to study the mechanisms of action of isolated natural products.

    Objective:To assess the antifungal activity of hexane, ethyl acetate and methanol extracts of 45 medicinal plants and to determine the minimum inhibitory concentration for each extract against human pathogenic fungi. Methods:A total of 45 medicinal plants were collected from different places of Tamil Nadu and identified. Hexane, ethyl acetate and methanol extracts of 45 medicinal plants were assessed for antifungal susceptibility using broth microdilution method. Two known antifungal agents were used as positive controls. Results: Most of the extracts inhibited more than four fungal strains. From the evaluation we found that ethyl acetate extracts inhibited large number of fungal growth. Hexane extracts also nearly showed the same level of inhibition against fungal growth. Methanol extracts showed the minimum antifungal activity. Among the 45 plants tested, broad spectrum antifungal activity was detected in Albizzia procera (A. procera), Atalantia monophylla, Asclepias curassavica, Azima tetracantha, Cassia fistula (C. fistula), Cinnomomum verum, Costus speciosus (C. speciosus), Nymphaea stellata, Osbeckia chinensis, Piper argyrophyllum, Punica granatum, Tinospora cordifolia and Toddalia asiatica (T. asiatica). Promising antifungal activity was seen in A. procera, C. speciosus, C. fistula and T. asiatica. Conclusions:It can be concluded that the plant species assayed possess antifungal properties. Further phytochemical research is needed to identify the active principles responsible for the antifungal effects of some of these medicinal plants.

    Folk medicinal practitioners form the first tier of primary health-care providers to most of the rural population of Bangladesh. They are known locally as Kavirajes and rely almost solely on oral or topical administration of whole plants or plant parts for treatment of various ailments. Also about 2% of the total population of Bangladesh are scattered among more than twenty tribes residing within the country's borders. The various tribes have their own tribal practitioners, who use medicinal plants for treatment of diseases. The objective of the present survey was to conduct an ethnomedicinal survey among the Kavirajes and tribal practitioners to determine which species of plants belonging to the Verbenaceae family are used by the practitioners. The Verbenaceae family plants are well known for constituents having important bio-active properties. The present survey indicated that 13 species belonging to 8 genera are used by the folk and tribal medicinal practitioners of Bangladesh. A comparison of their folk medicinal uses along with published reports in the scientific literature suggests that the Verbenaceae family plants used in Bangladesh can potentially be important sources of lead compounds or novel drugs for treatment of difficult to cure debilitating diseases like malaria and rheumatoid arthritis.

    Full Text Available Depression is a life-threatening, debilitating, and common disease affecting different segments of community. Chemical and synthetic drugs available to treat this disease cause many adverse effects and may lead to complete recovery in only 50% of patients. At the same time, medicinal plants have been reported to exert optimal pharmacological effects in treating depression in different models. In this review, the relevant articles indexed in the reliable databases PubMed, PubMed central, Scopus and Web of Science were review-ed. The review indicated that most medicinal plants exerted antidepressant effects through synaptic regulation of serotonin, noradrenaline, and dopamine, regulating activity of hypothalamic-pituitary-adrenal axis, reinfor-cing anti-oxidant defense system, and decreasing inflammatory mediators. The medicinal plants and their active compounds can relieve depression through different pathways and hence are considered a new source to produce antidepressants.

    Cancer is the second cause of death after cardiovascular diseases. With due attention to rapid progress in the phytochemical study of plants, they are becoming popular because of their anticancer effects. The aim of this study was to investigate the effective medicinal plants in the treatment of cancer and study their mechanism of action. In order to gather information the keywords "traditional medicine," "plant compounds," "medicinal plant," "medicinal herb," "toxicity," "anticancer effect," "cell line," and "treatment" were searched in international databases such as ScienceDirect, PubMed, and Scopus and national databases such as Magiran, Sid, and Iranmedex, and a total of 228 articles were collected. In this phase, 49 nonrelevant articles were excluded. Enhancement P53 protein expression, reducing the expression of proteins P27, P21, NFκB expression and induction of apoptosis, inhibition of the PI3K/Akt pathway, and reduction of the level of acid phosphatase and lipid peroxidation are the most effective mechanisms of herbal plants that can inhibit cell cycle and proliferation. Common treatments such as radiotherapy and chemotherapy can cause some complications. According to results of this study, herbal extracts have antioxidant compounds that can induce apoptosis and inhibit cell proliferation by the investigated mechanisms.

    Full Text Available Hypertrophic scar is a complication of wound healing and has a high recurrence rate which can lead to significant abnormity in aesthetics and functions. To date, no ideal treatment method has been established. Meanwhile, the underlying mechanism of hypertrophic scarring has not been clearly defined. Although a large amount of scientific research has been reported on the use of medicinal plants as a natural source of treatment for hypertrophic scarring, it is currently scattered across a wide range of publications. Therefore, a systematic summary and knowledge for future prospects are necessary to facilitate further medicinal plant research for their potential use as antihypertrophic scar agents. A bibliographic investigation was accomplished by focusing on medicinal plants which have been scientifically tested in vitro and/or in vivo and proved as potential agents for the treatment of hypertrophic scars. Although the chemical components and mechanisms of action of medicinal plants with antihypertrophic scarring potential have been investigated, many others remain unknown. More investigations and clinical trials are necessary to make use of these medical plants reasonably and phytotherapy is a promising therapeutic approach against hypertrophic scars.

    Recent advances in agricultural biotechnology have enabled the field of plant biology to move forward in great leaps and bounds. In particular, recent breakthroughs in molecular biology, plant genomics and crop science have brought about a paradigm shift of thought regarding the manner by which plants can be utilized both in agriculture and in medicine. Besides the more well known improvements in agronomic traits of crops such as disease resistance and drought tolerance, plants can now be associated with topics as diverse as biofuel production, phytoremediation, the improvement of nutritional qualities in edible plants, the identification of compounds for medicinal purposes in plants and the use of plants as therapeutic protein production platforms. This diversification of plant science has been accompanied by the great abundance of new patents issued in these fields and, as many of these inventions approach commercial realization, the subsequent increase in agriculturally-based industries. While this review chapter is written primarily for plant scientists who have great interest in the new directions being taken with respect to applications in agricultural biotechnology, those in other disciplines, such as medical researchers, environmental scientists and engineers, may find significant value in reading this article as well. The review attempts to provide an overview of the most recent patents issued for plant biotechnology with respect to both agriculture and medicine. The chapter concludes with the proposal that the combined driving forces of climate change, as well as the ever increasing needs for clean energy and food security will play a pivotal role in leading the direction for applied plant biotechnology research in the future.

    Approximately 80% of the world inhabitants depend on the medicinal plants in the form of traditional formulations for their primary health care system well as in the treatment of a number of diseases since the ancient time. Many commercially used drugs have come from the information of indigenous knowledge of plants and their folk uses. Linking of the indigenous knowledge of medicinal plants to modern research activities provides a new reliable approach, for the discovery of novel drugs much more effectively than with random collection. Increase in population and increasing demand of plant products along with illegal trade are causing depletion of medicinal plants and many are threatened in natural habitat. Plant tissue culture technique has proved potential alternative for the production of desirable bioactive components from plants, to produce the enough amounts of plant material that is needed and for the conservation of threatened species. Different plant tissue culture systems have been extensively studied to improve and enhance the production of plant chemicals in various medicinal plants.

    Full Text Available Abstract The success of snake bite healers is vaguely understood in Kenya, partly due to their unknown materia medica and occult-mystical nature of their practice. A comparison is made of plants used in snake bite treatments by two culturally distinct African groups (the Kamba and Luo. Thirty two plants used for snakebite treatment are documented. The majority of the antidotes are prepared from freshly collected plant material – frequently leaves. Though knowledge of snake bite conditions etiological perceptions of the ethnic groups is similar, field ethnobotanical data suggests that plant species used by the two ethnic groups are independently derived. Antivenin medicinal plants effectively illustrate the cultural context of medicine. Randomness or the use of a variety of species in different families appears to be a feature of traditional snake bite treatments. A high degree of informant consensus for the species was observed. The study indicates rural Kenya inhabitants rely on medicinal plants for healthcare.

    Polygonum L. s. str., belonging to Polygonaceae family, is a big genus with abundant medicinal plants. More than 10 plants are specified in Chinese Pharmacopoeia and many local medicinal standards and over 50 species are used as folk medicines. Owing to the similar morphologies and very small flowers and fruits, they are uneasily identified and often confused with each other and misused clinically. In order to provide a basis for identification of Polygonum s. str. plants, a histological study on stems and leaves of 30 species from Polygonum was undertaken by a routine/polarized light microscopy for the first time. The results showed that: (1) the transverse sections of stems of Polygonum are relatively similar, sclerenchyma such as xylem and fibres with strong polarization effects; (2) the surface views of leaves of Polygonum are distinguishable on distributions and types of stomata, with or without attachments (such as glandular hairs/scales or non-glandular hairs) and the polariscopic features of epidermal cell walls, stomata and cell contents. Observed under polarized light, it was found for the first time that stomata on leaf surface of some plants have a Maltese-cross effect with the arms of the cross intersecting at the stomatal opening. As a result, a key combining the microscopic and polariscopic characteristics of the stems as well as leaves was provided for identifying the 30 medicinal plants of Polygonum. The polarized light microscopic method was proven to be one of the quick, simple and effective techniques for the identification of medicinal plants and botanic crude materials.

    Full Text Available Non-probability sampling design can be used in ethnobotanical surveys of medicinal plants. However, this method does not allow statistical inferences to be made from the data generated. The aim of this paper is to present a probability sampling design that is applicable in ethnobotanical studies of medicinal plants. The sampling design employed in the research titled "Ethnobotanical knowledge of medicinal plants used by traditional communities of Nossa Senhora Aparecida do Chumbo district (NSACD, Poconé, Mato Grosso, Brazil" was used as a case study. Probability sampling methods (simple random and stratified sampling were used in this study. In order to determine the sample size, the following data were considered: population size (N of 1179 families; confidence coefficient, 95%; sample error (d, 0.05; and a proportion (p, 0.5. The application of this sampling method resulted in a sample size (n of at least 290 families in the district. The present study concludes that probability sampling methods necessarily have to be employed in ethnobotanical studies of medicinal plants, particularly where statistical inferences have to be made using data obtained. This can be achieved by applying different existing probability sampling methods, or better still, a combination of such methods.

    Pain is normally treated with oral nonsteroidal anti-inflammatory agents and opioids. These drugs are dangerous and are responsible for many hospitalizations and deaths. It is much safer to use topical preparations made from plants to treat pain, even severe pain. Topical preparations must contain compounds that penetrate the skin, inhibit pain receptors such as transient receptor potential cation channels and cyclooxygenase-2, to relieve pain. Inhibition of pain in the skin disrupts the pain cycle and avoids exposure of internal organs to large amounts of toxic compounds. Use of topical pain relievers has the potential to save many lives, decrease medical costs and improve therapy.

    Full Text Available Halitosis is an oral health condition characterized by unpleasant odors emanating constantly from oral cavity. Almost 22-50% of the population experiences such a condition during lifespan and about half of them suffer from personal discomfort and social embarrassment. Based on the literature survey, it seems that the oral cavity is the most important origin of halitosis; therefore, this area could be considered as the best target for the treatment. Halitosis is a well-known disorder in Iranian Traditional Medicine (ITM; Avicenna and some other famous Iranian traditional physicians have described this condition in their manuscripts precisely. Herbal therapy was the major treatment suggested by Iranian scholars in which mixtures of medicinal plants were used in the form of mouthwashes and other oral formulations. In the present study, six Iranian ancient medical texts were screened for the herbs with anti-halitosis effects. Subsequent to this study, the medicinal herbs were listed and scored based on the frequency of their repetition. Moreover, the effort has been taken to provide the best scientific name for each plant as well as searching modern studies about their biological effects. In our investigation fourteen plants were obtained as the most frequent herbs for treatment of halitosis in ITM. Previous studies revealed that some of these plants have shown biological activities relating to anti-halitosis effect. The present study introduces some more plants for future studies about anti-halitosis property.

    Hexane, ethylacetate (EtOAC), and n-butanol (n-BuOH) extracts of medicinal plants traditionally used in the East Asia, such as China, Korea, and Japan were screened for their vasorelaxant activity using isolated rat aorta. Among the 60 solvent-extracts from 20 medicinal plants, hexane and n-BuOH extracts of Diospyros kaki and Polygonum aviculare, hexane, EtOAC, and n-BuOH extracts of Magnolia liliflora, n-BuOH extract of Sorbus commixta, and EtOAC and n-BuOH extracts of Selaginella tamariscina were found to exhibit distinctive vasorelaxant activity. The activity disappeared by removal of functional endothelium or pre-treatment of the aortic tissues with N(G)-nitro-L-arginine methyl ester (L-NAME), which is an inhibitor of nitric oxide synthase. These findings suggest that the medicinal plants relax vascular smooth muscle via endothelium-dependent nitric oxide. These results will be useful to further analyze those medicinal plants that contain the vasorelaxant activity in order to identify the active principles.

    Full Text Available Medicinal plants provide indigenous and peasant communities worldwide with means to meet their healthcare needs. Homegardens often act as medicine cabinets, providing easily accessible medicinal plants for household needs. Social structure and social exchanges have been proposed as factors influencing the species diversity that people maintain in their homegardens. Here, we assess the association between the exchange of medicinal knowledge and plant material and medicinal plant richness in homegardens. Using Tsimane' Amazonian homegardens as a case study, we explore whether social organization shapes exchanges of medicinal plant knowledge and medicinal plant material. We also use network centrality measures to evaluate people's location and performance in medicinal plant knowledge and plant material exchange networks. Our results suggest that social organization, specifically kinship and gender relations, influences medicinal plant exchange patterns significantly. Homegardens total and medicinal plant species richness are related to gardeners' centrality in the networks, whereby people with greater centrality maintain greater plant richness. Thus, together with agroecological conditions, social relations among gardeners and the culturally specific social structure seem to be important determinants of plant richness in homegardens. Understanding which factors pattern general species diversity in tropical homegardens, and medicinal plant diversity in particular, can help policy makers, health providers, and local communities to understand better how to promote and preserve medicinal plants in situ. Biocultural approaches that are also gender sensitive offer a culturally appropriate means to reduce the global and local loss of both biological and cultural diversity.

We also use network centrality measures to evaluate people's location and performance in medicinal plant knowledge and plant material exchange networks. Our results suggest that social organization, specifically kinship and gender relations, influences medicinal plant exchange patterns significantly. Homegardens total and medicinal plant species richness are related to gardeners' centrality in the networks, whereby people with greater centrality maintain greater plant richness. Thus, together with agroecological conditions, social relations among gardeners and the culturally specific social structure seem to be important determinants of plant richness in homegardens. Understanding which factors pattern general species diversity in tropical homegardens, and medicinal plant diversity in particular, can help policy makers, health providers, and local communities to understand better how to promote and preserve medicinal plants in situ. Biocultural approaches that are also gender sensitive offer a culturally appropriate means to reduce the global and local loss of both biological and cultural diversity.

    The present study was designed to document detailed ethnogynaecological knowledge of selected remote regions of Pashtun's tribe in northwest Pakistan. Semistructured questionnaires were designed to collect ethnogynaecological and ethnographic data. Total of 51 medicinal plants belonging to 36 families were documented that were used by the women of studied regions for the treatment of 9 types of gynaecological complaints. Majority of the plants (19) were found used against menses followed by 11 plants each for gonorrhea and pregnancy. Bannu region has high number of gynaecological plants (22) followed by Karak (15). Women of the regions mostly used whole plants (33%) and leaves (31%) for various ethnomedicinal preparation of gynae. Fic results showed that all ailments in different areas scored high consensus ranges between 0.6 and 1.00. Majority of the female respondents (44%) were aged between 61 and 70 years, of which most were illiterate. Women in the remote regions of Pakistan have tremendous traditional knowledge in utilizing medicinal plants for their reproductive health. Plants with high Fic values should be cross-checked for their in vitro and in vivo validation. Young girls should be educated on the importance of ethnogynaecological practices to conserve this valuable knowledge.

    Applicability of our computer programs PASS and PharmaExpert to prediction of biological activity spectra of rather complex and structurally diverse phytocomponents of medicinal plants, both separately and in combinations has been evaluated. The web-resource on phytochemicals of 50 medicinal plants used in Ayurveda was created for the study of hidden therapeutic potential of Traditional Indian Medicine (TIM) (http://ayurveda.pharmaexpert.ru). It contains information on 50 medicinal plants, their using in TIM and their pharmacology activities, also as 1906 phytocomponents. PASS training set was updated by addition of information about 946 natural compounds; then the training procedure and validation were performed, to estimate the quality of PASS prediction. It was shown that the difference between the average accuracy of prediction obtained in leave-5%-out cross-validation (94,467%) and in leave-one-out cross-validation (94,605%) is very small. These results showed high predictive ability of the program. Results of biological activity spectra prediction for all phytocomponents included in our database are in good correspondence with the experimental data. Additional kinds of biological activity predicted with high probability provide the information about most promising directions of further studies. The analysis of prediction results of sets of phytocomponents in each of 50 medicinal plants was made by PharmaExpert software. Based on this analysis, we found that the combination of phytocomponents from Passiflora incarnata may exhibit nootropic, anticonvulsant and antidepressant effects. Experiments carried out in mice models confirmed the predicted effects of Passiflora incarnata extracts.

    Full Text Available The aim of this study was to present the implications of the use of herbs during pregnancy, pointing out those that should be avoided during this condition because of their abortifacient and/or teratogenic potential. We carried out searches in the databases ScienceDirect, Scielo and Google Scholar, adopting as criteria for inclusion: book chapters and/or complete articles (with abstract, available in English, Portuguese or Spanish, published from 1996 to in 2011. After a pre-selection of 83 articles, 49 bibliographies were used in the manufacturing end of the article, where 25 were from the Scielo database, 18 from ScienceDirect and 6 from Google Scholar. From the articles studied, we identified the four most commonly used plants as emmenagogue/abortifacient agents by patients of the Department of Prenatal SUS: senne, arruda, boldo and buchinha-do-norte or cabacinha. Thus, we conclude that people often adhere to the maxim "if it's natural, it does no harm" in their rational use of natural products, without the right guidance, believing that these products are safe to use. This usage is even more worrisome among the elderly, pregnant women and children. Regarding the safety of these products, some information and reliable data are scarce or contradictory.Este trabalho busca as implicações atuais sobre o uso de plantas medicinais durante a gravidez, alertando sobre aquelas que devem ser evitadas nesse período por serem potencialmente abortivas e/ou teratogênicas.

    Full Text Available Ulcer is a common gastrointestinal disorder which is seen among many people. It is basically an inflamed break in the skin or the mucus membrane lining the alimentary tract. Ulceration occurs when there is a disturbance of the normal equilibrium caused by either enhanced aggression or diminished mucosal resistance. It may be due to the regular usage of drugs, irregular food habits, stress, and so forth. Peptic ulcers are a broad term that includes ulcers of digestive tract in the stomach or the duodenum. The formation of peptic ulcers depends on the presence of acid and peptic activity in gastric juice plus a breakdown in mucosal defenses. A number of synthetic drugs are available to treat ulcers. But these drugs are expensive and are likely to produce more side effects when compared to herbal medicines. The literature revealed that many medicinal plants and polyherbal formulations are used for the treatment of ulcer by various ayurvedic doctors and traditional medicinal practitioners. The ideal aims of treatment of peptic ulcer disease are to relieve pain, heal the ulcer, and delay ulcer recurrence. In this review attempts have been made to know about some medicinal plants which may be used in ayurvedic as well as modern science for the treatment or prevention of peptic ulcer.

Selected phytochemicals were investigated in more detail for their modes of action. Methods. A modified chicken-chorioallantoic-membrane (CAM assay using quail eggs was applied to test for antiangiogenic effects of plant extracts. A molecular docking in silico approached the binding of plant constituents to the vascular endothelial growth factor receptors 1 and 2 (VEGFR1, VEGFR2. Microarray-based mRNA expression profiling was employed to correlate the 50% inhibition concentrations (IC50 of a panel of 60 NCI cell lines to these phytochemicals. Results. Extracts from Acer mono leaves, Reynoutria sachalniensis fruits, Cinnamomum japonicum stems, Eurya japonica leaves, Adenophora racemosa whole plant, Caryopteris incana leaves-stems, and Schisandra chinensis stems inhibited angiogenesis more than 50% in quail eggs. Selected phytochemicals from Korean plants were analyzed in more detail using microarray-based mRNA expression profiles and molecular docking to VEGFR1 and VEGFR2. These results indicate multifactorial modes of action of these natural products. Conclusion. The antiangiogenic activity of plants used in traditional Korean medicine implicates their possible application for diseases where inhibition of blood vessel formation is desired, for example, cancer, macular degeneration, diabetic retinopathy and others.

Three medicinal plants, namely Zingiber officinale (Ginger), Allium sativum (Garlic) and Capsicum annuum (Chili) were chosen as grafting agent to decrease the side-effects and increase the efficiency of NPs towards living organism. Extraction conditions were controlled under 60-100 °C for 8 hrs. Ag and TiO2 NPs were fabricated using colloidal chemistry and variables were controlled at ambient condition. The band gap of TiO2 NPs used as disinfectant was also modified through coating the medicinal plant extracts. The medicinal plant extracts and coated NPs were measured using spectroscopic methods. Ultraviolet-visible spectra indicated the Ag NPs were formed. The peak at 410 nm resulted from the electrons transferred from their ground to the excited state. The broadened full width at half maximum (FWHM) suggested the ultrafine particles were obtained. The lipid soluble compounds, phenols, tri-terpenoids, flavanoids, capsaicinoids, flavonoids, carotenoids, steroids steroidal glycosides, and vitamins were determined from the high performance liquid chromatographical analyses. X-ray powder diffraction indicated that the face-centered cubic Ag (PDF: 00-004-0783, a = 4.0862A, a = 90°) and anatase TiO2 (PDF: 01-08-1285, a = 3.7845, c = 9.5143A, a = 90°) were obtained using colloidal chemistry. Bactericidal activity indicated that these core-shelled TiO 2 were effective (MBC=0.6 ppm, within 30 mins) at inactivating Gram-positive and Gram-negative bacteria. It is proposed that the medicinal extracts enhanced the potency of NPs against bacteria. From our previous study, the Ag NPs were highly effective at inactivating both bacteria.

    Heliotropium kotschyi (Ramram) is an important endangered medicinal plant distributed in the Kingdom of Bahrain. Plant tissue culture technique is applied for ex situ conservation study. Nodal stem segments are cultured in modified MS media supplemented with various combination and concentration of plant growth regulators (PGRs). Plants are regenerated via shoot organogenesis from the nodal meristems. Plants are regenerated in three different steps: initial shoot development, shoot multiplication, and rooting. After 4 weeks of culture, 100 % explants respond to shoot initiation on the medium containing 8.88 μM BAP and 5.71 μM IAA. The highest frequency of shoot regeneration is observed in the same media after second subculture of shoots. The highest rooting frequency is observed in the presence of 2.85 μM IAA. After root development, the plantlets are transferred to pots filled with soil and 60 % of plants survived after 45 days. This plant regeneration protocol is of great value for rapid desert plant propagation program.

  17. Crop and medicinal plants proteomics in response to salt stress

    Full Text Available Increasing of world population marks a serious need to create new crop cultivars and medicinal plants with high growth and production at any environmental situations. Among the environmental unfavorable conditions, salinity is the most widespread in the world. Crop production and growth severely decreases under salt stress; however, some crop cultivars show significant tolerance against the negative effects of salinity. Among salt stress responses of crops, proteomic responses play a pivotal role in their ability to cope with it and have become the main center of notification. Many physiological responses are detectable in terms of protein increase and decrease even before physiological responses take place. Thus proteomic approach makes a short cut in the way of inferring how crops response to salt stress. Nowadays many salt-responsive proteins such as heat shock proteins, pathogen related proteins, protein kinases, ascorbate peroxidase, osmotin, ornithine decarboxylase and some transcription factors, have been detected in some major crops which are thought to give them the ability of withstanding against salt stress. Proteomic analysis of medicinal plants also revealed that alkaloid biosynthesis related proteins such as tryptophan synthase, codeinone reductase, strictosidine synthase and 12-oxophytodienoate reductase might have major role in production of secondary metabolites. In this review we are comparing some different or similar proteomic responses of several crops and medicinal plants to salt stress and discuss about the future prospects.

    Drought stress exerts a considerable effect on growth, physiology and secondary metabolisms of the medicinal plants. It could inhabit the growth of the medicinal plants but promote secretion of secondary metabolites. Other researches indicated that the medicinal plants could depend on the ABA signaling pathway and secreting osmotic substances to resist the drought stress and reduce the damage by it. The article concludes the changes in growth, physiology, secondary metabolisms and response mechanisms of medicinal plants to drought stress that provides a theoretical basis for exploring the relationship between medicinal plants and drought stress.

    Medicinal plants have been used world-wide for thousands of years and are widely recognized as having high healing but minor toxic side effects. The scarcity and increasing demand for medicinal plants and their products have promoted the development of artificial cultivation of medicinal plants. Currently, one of the prominent issues in medicinal cultivation systems is the unstable quality of the products. Arbuscular mycorrhiza (AM) affects secondary metabolism and the production of active ingredients of medicinal plants and thus influence the quality of herbal medicines. In this review, we have assembled, analyzed, and summarized the effects of AM symbioses on secondary metabolites of medicinal plants. We conclude that symbiosis of AM is conducive to favorable characteristics of medicinal plants, by improving the production and accumulation of important active ingredients of medicinal plants such as terpenes, phenols, and alkaloids, optimizing the composition of different active ingredients in medicinal plants and ultimately improving the quality of herbal materials. We are convinced that the AM symbiosis will benefit the cultivation of medicinal plants and improve the total yield and quality of herbal materials. Through this review, we hope to draw attention to the status and prospects of, and arouse more interest in, the research field of medicinal plants and mycorrhiza.

    Arthropods were sampled from feverfew [Tanacetum parthenium (L.) SchultzBip], Echinaceapurpurea (L.) Moench, Echinaceapallida (Nutt.) Nutt., Valeriana officinalis L., and St. John's wort (Hypericum perforatum L.) during 1998-2001. In addition,arthropods were sampled on tansy (Tanacetum vulgare L.) from 2001-2004. In general,50-60 arthropod species where collected and identified among all of the medicinal plant species. Among the predators, Orius insidiosus (Say) (Hemiptera: Anthocoridae), Geocoris punctipes (Say) (Hemiptera: Lygaeidae) and spiders were most abundant from 1998-2004.The three-cornered alfalfa hopper, Spissistilus festinus (Say), was the most abundant herbivore found from 1998 to 2001. Orius insidiosus and G. punctipes were 3-4 times more abundant on T. parthenium than on any other medicinal plant species. Based on the numbers of predatory arthropods found on T. parthenium, this crop could be suitable as a companion or "banker" plant to attract and maintain populations of predators, especially O. insidiosus and G. punctipes. Whitefly nymphs attacked by predators with piercing/sucking mouthparts are easily identified using a microscope because of the general appearance of the carcass left by the predators. Thus, populations of predators on T. parthenium suppressed Bemisia tabaci populations on E. purpurea when these crops were planted as companion crops.

    Full Text Available Medicinal plants are the source for wide variety of natural antioxidants. In the study reported here, we have conducted a comparative study between the different parts of the plant Enicostemma littorale. The amount of total phenols and antioxidant enzymes Glutathione-S-Transferase, Superoxide Dismutase, Catalase and Peroxidase activities were evaluated and also the non-enzymatic antioxidants ascorbic acid, α- tocopherol and Glutathione activities were evaluated. The results showed that the antioxidant activities varied greatly among the different plant parts used in this study and some parts are rich in natural antioxidants especially the flowers of E. littorale. These results suggest that Enicostemma littorale have strong antioxidant potential. Further study is necessary for isolation and characterization of antioxidant agents, which can be used to treat various oxidative stress-related diseases.

    2011-12-01

    An escalating "epidemic" of diseases like Alzheimer's has not yet been met by effective symptomatic treatments or preventative strategies. Among a few current prescription drugs are cholinesterase inhibitors including galantamine, originating from the snowdrop. Research into ethnobotanicals for memory or cognition has burgeoned in recent years. Based on a multi-faceted review of medicinal plants or phytochemicals, including traditional uses, relevant bioactivities, psychological and clinical evidence on efficacy and safety, this overview focuses on those for which there is promising clinical trial evidence in people with dementia, together with at least one other of these lines of supporting evidence. With respect to cognitive function, such plants reviewed include sage, Ginkgo biloba, and complex mixtures of other traditional remedies. Behavioral and psychological symptoms of dementia (BPSD) challenge carers and lead to institutionalization. Symptoms can be alleviated by some plant species (e.g., lemon balm and lavender alleviate agitation in people with dementia; St John's wort treats depression in the normal population). The ultimate goal of disease prevention is considered from the perspective of limited epidemiological and clinical trial evidence to date. The potential value of numerous plant extracts or chemicals (e.g., curcumin) with neuroprotective but as yet no clinical data are reviewed. Given intense clinical need and carer concerns, which lead to exploration of such alternatives as herbal medicines, the following research priorities are indicated: investigating botanical agents which enhance cognition in populations with mild memory impairment or at earliest disease stages, and those for BPSD in people with dementia at more advanced stages; establishing an ongoing authoritative database on herbal medicine for dementia; and further epidemiological and follow up studies of promising phytopharmaceuticals or related nutraceuticals for disease prevention.

    The medicinal plant Pelargonium sidoides DC. (Geraniaceae) was traditionally used for the treatment of the common cold and cough in South Africa. Today an aequous-ethanolic root extract from this plant is approved for the treatment of acute bronchitis and is globally marketed also as an immunostimulant. The increasing demand of the plant material for the industrial production indicates the need of new effective methods for the propagation of P. sidoides. Here we report somatic embryogenesis and in vitro plantlet regeneration from somatic cells of inflorescence shoots and petioles of P. sidoides. A one-week cultivation of explants in media containing different concentrations of thidiazuron (1, 2.2, 3, and 4 mg/L) followed by a cultivation period without phytohormones resulted in the induction of somatic embryos within 2-4 weeks. After 2-4 months, the embryos generated roots and could be transferred into a greenhouse, where flower formation took place and the development of seeds occurred with high germination rates. The root umckalin concentration, determined by high-performance thin-layer chromatography, was comparable to that of seed-cultivated plants (100 ± 6 vs. 113 ± 10 µg umckalin/g dried roots). For the first time, direct somatic embryogenesis has been established as an appropriate cultivation method for P. sidoides plants used as raw material in the pharmaceutical industry. Moreover, genetically identical plants (chemical races) can be easily generated by this procedure.

  9. Molecular identification of commercialized medicinal plants in southern Morocco.

    Anneleen Kool

    Full Text Available BACKGROUND: Medicinal plant trade is important for local livelihoods. However, many medicinal plants are difficult to identify when they are sold as roots, powders or bark. DNA barcoding involves using a short, agreed-upon region of a genome as a unique identifier for species- ideally, as a global standard. RESEARCH QUESTION: What is the functionality, efficacy and accuracy of the use of barcoding for identifying root material, using medicinal plant roots sold by herbalists in Marrakech, Morocco, as a test dataset. METHODOLOGY: In total, 111 root samples were sequenced for four proposed barcode regions rpoC1, psbA-trnH, matK and ITS. Sequences were searched against a tailored reference database of Moroccan medicinal plants and their closest relatives using BLAST and Blastclust, and through inference of RAxML phylograms of the aligned market and reference samples. PRINCIPAL FINDINGS: Sequencing success was high for rpoC1, psbA-trnH, and ITS, but low for matK. Searches using rpoC1 alone resulted in a number of ambiguous identifications, indicating insufficient DNA variation for accurate species-level identification. Combining rpoC1, psbA-trnH and ITS allowed the majority of the market samples to be identified to genus level. For a minority of the market samples, the barcoding identification differed significantly from previous hypotheses based on the vernacular names. CONCLUSIONS/SIGNIFICANCE: Endemic plant species are commercialized in Marrakech. Adulteration is common and this may indicate that the products are becoming locally endangered. Nevertheless the majority of the traded roots belong to species that are common and not known to be endangered. A significant conclusion from our results is that unknown samples are more difficult to identify than earlier suggested, especially if the reference sequences were obtained from different populations. A global barcoding database should therefore contain sequences from different populations of the

    Full Text Available Tuberculosis (TB remains a serious health problem in many regions of the world, and the development of resistance to antibiotics by this microbe created the need for new drugs to replace those which have lost effectiveness. This study assesses the medicinal anti-Mycobacterium tuberculosis properties of natural products obtained from plants collected from Eastern Libya. In this study aqueous extracts of nine different plants were assayed for their Mycobacterium tuberculosis inhibitory activity using the BACTEC MGIT960 susceptibility test method. The aqueous extracts of Ceratonia siliqua L, Helichrysum stoechas (L. Moench and Thymus algeriensis did not show any activity against M. tuberculosis in different concentrations. The aqueous extract of Marrubium vulgare L. from Syria showed high activity against M. tuberculosis. Marrubium alysson L., Marrubium vulgare L., Pistacia lentiscus L, Quercus coccifera L, Thymus capitatus (L. Hoffm. & Link, showed varying degrees of activity against M. tuberculosis. The results of this study show that aqueous extracts from six different medicinal plants have different effects against M. tuberculosis in vitro.

    Objective:To determine the antimoraxella activity of Ethiopian medicinal plants extracts. Methods:Two clinical isolates ofMoraxella cattarhalis (M. cattarhalis) with different antibiotic sensitivity pattern were tested to determine their susceptibility to garlic [Allium sativum (A. sativum)], bark of cinnamon [Cinnamomum zeylanicum (C. zeylanicum)], clove [Syzygium aromaticum (S. aromaticum)], and leaves of avocado [Persea americana (P. americana)], rosemary [Rosmarinus officinalis (R. officinalis)] and prickly poppy [Argemone mexicana (A. mexicana)]. Disk diffusion assay and broth dilution method were used to measure zone of inhibition, minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of plant extracts againstM. cattarhalis.Results: Both the strains ofM. cattarhalis exhibited similar sensitivities to the extracts of medicinal plants. Antimoraxella activity was exhibited only by garlic, avocado leaves and cinnamon. Garlic was found to be more antagonistic toM. cattarhalisthan cinnamon and avocado. Garlic and avocado leaves have shown similar MIC(30 mg/mL) where as their zone of inhibition (15 and11mm, respectively) were different. Conclusions: Garlic, cinnamon and avocado leaves extracts represents alternative source of natural antimicrobial substances for use in clinical practice for the treatment of cases ofM. cattarhalis. Further research on the effects of these extracts onM. cattarhalis can be rewarding to pursue in the search for new broad spectrum antimicrobial agents.

    Ethnopharmacological relevance Tuberculosis (TB) caused by Mycobacterium tuberculosis remains an ongoing threat to human health. Several medicinal plants are used traditionally to treat tuberculosis in Ghana. The current study was designed to investigate the antimycobacterial activity and cytotoxicity of crude extracts from five selected medicinal plants. Material and methods The microplate alamar blue assay (MABA) was used for antimycobacterial studies while the CellTiter 96® AQueous Assay, which is composed of solutions of a novel tetrazolium compound [3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium, inner salt; MTS] and an electron coupling reagent (phenazine methosulfate) PMS, was used for cytotoxic studies. Correlation coefficients were used to compare the activity of crude extracts against nonpathogenic strains and the pathogenic Mycobacterium tuberculosis subsp.tuberculosis. Results Results of the MIC determinations indicated that all the crude extracts were active on all the three tested mycobacterial strains. Minimum inhibitory concentration values as low as 156.3 µg/mL against M. tuberculosis; Strain H37Ra (ATCC® 25,177™) were recorded from the leaves of Solanum torvum Sw. (Solanaceae). Cytotoxicity of the extracts varied, and the leaves from S. torvum had the most promising selectivity index. Activity against M. tuberculosis; Strain H37Ra was the best predictor of activity against pathogenic Mycobacterium tuberculosis subsp.tuberculosis (correlation coefficient=0.8). Conclusion The overall results of the present study provide supportive data on the use of some medicinal plants for tuberculosis treatment. The leaves of Solanum torvum are a potential source of anti-TB natural products and deserve further investigations to develop novel anti-TB agents against sensitive and drug resistant strains of M. tuberculosis.

    Medicinal plants have been used in healthcare since time immemorial. Studies have been carried out globally to verify their efficacy and some of the findings have led to the production of plant-based medicines. The global market value of medicinal plant products exceeds $100 billion per annum. This paper discusses the role, contributions and usefulness of medicinal plants in tackling the diseases of public health importance, with particular emphasis on the current strategic approaches to disease prevention. A comparison is drawn between the 'whole population' and 'high-risk' strategies. The usefulness of the common-factor approach as a method of engaging other health promoters in propagating the ideals of medicinal plants is highlighted. The place of medicinal plants in preventing common diseases is further examined under the five core principles of the Primary Health Care (PHC) approach. Medicinal plants play vital roles in disease prevention and their promotion and use fit into all existing prevention strategies. However, conscious efforts need to be made to properly identify, recognise and position medicinal plants in the design and implementation of these strategies. These approaches present interesting and emerging perspectives in the field of medicinal plants. Recommendations are proposed for strategising the future role and place for medicinal plants in disease prevention.

    In Mediterranean cultures written records of medicinal plant use have a long tradition. This written record contributed to building a consensus about what was perceived to be an efficacious pharmacopeia. Passed down through millennia, these scripts have transmitted knowledge about plant uses, with high fidelity, to scholars and laypersons alike. Herbal medicine's importance and the long-standing written record call for a better understanding of the mechanisms influencing the transmission of contemporary medicinal plant knowledge. Here we contextualize herbal medicine within evolutionary medicine and cultural evolution. Cumulative knowledge transmission is approached by estimating the causal effect of two seminal scripts about materia medica written by Dioscorides and Galen, two classical Greco-Roman physicians, on today's medicinal plant use in the Southern Italian regions of Campania, Sardinia, and Sicily. Plant-use combinations are treated as transmissible cultural traits (or "memes"), which in analogy to the biological evolution of genetic traits, are subjected to mutation and selection. Our results suggest that until today ancient scripts have exerted a strong influence on the use of herbal medicine. We conclude that the repeated empirical testing and scientific study of health care claims is guiding and shaping the selection of efficacious treatments and evidence-based herbal medicine.

    Casearia grandiflora (Salicaceae) is a typical Cerrado species adapted to disturbed environments, making it useful for restoration projects. Knowledge of genetic diversity is important for establishing conservation strategies for this species. This study aimed to compare chloroplast haplotype diversity and structure of C. grandiflora, under the assumption that protected areas hold greater genetic diversity than disturbed areas. The populations studied are from Parque Nacional de Sete Cidades Conservation Unit and from the surroundings of the city of Cocal de Telha, both located in the State of Piauí. Molecular analyses were performed with seven chloroplast microsatellite loci. The number of private haplotypes and haplotype diversity were higher in the conservation unit, which reinforces the importance of these areas in maintaining biodiversity. Analysis of molecular variance showed that most of the genetic variation is found within populations, with a moderate divergence between them (FST = 0.14). The Bayesian analysis and discriminant analysis of principal components suggested that populations are not structured, revealing that a set of individuals from Parque Nacional de Sete Cidades were more divergent within populations than between them. Since literature has little information on C. grandiflora, the results of this study provide important contribution to a better understanding of the specie's genetic diversity.

    The medicinal plant extracts commercially used in Asia were screened for their estrogenic and antiestrogenic activities in a recombinant yeast system featuring both a human estrogen receptor (ER) expression plasmid and a reporter plasmid. Pueraria lobata (flower) had the highest estrogenic relative potency (RP, 7.75×10(-3); RP of 17β-estradiol=1), followed by Amomum xanthioides (1.25×10(-3)). Next potent were a group consisting of Glycyrrhiza uralensis, Zingiber officinale, Rheum undulatum, Curcuma aromatica, Eriobotrya japonica, Sophora flavescens, Anemarrhena asphodeloides, Polygonum multiflorum, and Pueraria lobata (root) (ranging from 9.5×10(-4) to 1.0×10(-4)). Least potent were Prunus persica, Lycoppus lucidus, and Adenophora stricta (ranging from 9.0×10(-5) to 8.0×10(-5)). The extracts exerting antiestrogenic effects, Cinnamomum cassia and Prunus persica, had relative potencies of 1.14×10(-3) and 7.4×10(-4), respectively (RP of tamoxifen=1). The solvent fractions from selected estrogenic or antiestrogenic herbs had higher estrogenic relative potencies, with their RP ranging from 9.3×10(-1) to 2.7×10(-4) and from 8.2×10(-1) to 9.1×10(-3), respectively. These results support previous reports on the efficacy of Oriental medicinal plants used or not used as phytoestrogens for hormone replacement therapy.

    Full Text Available A peptic ulcer is erosion in a segment of the gastro intestinal mucosa. It may typically in the stomach (gastric ulcer or first few centimeters of duodenum (duodenal ulcer that penetrates through the muscularis mucosae. Contrary to popular belief, ulcer is not only caused by spicy food but also most commonly due to an infection of Helicobacter Pylori and long term use of medications. Standard treatment is a combination of drugs including antibiotics and a proton pump inhibitors. Literature suggests that number of synthetic drugs are used in the management of peptic ulcers but elicit several adverse effects. Therefore Indian herbal plants stand out as being exceptional for its ethnic, ethobotanical and ethno-pharmaceutical use. In this review attempts have been made to know about some plants which may be used in treatment or prevention of peptic ulcers. Various plants like Excoecaria agallocha, Mentha arvensis, Utleria salicifolia, Emblica officinalis etc. proved active in antiulcer therapy. This combination of traditional and modern knowledge can produced better antiulcer drugs with fewer side effects. The medicinal plants are available in India and other countries, recent technologies advances have renewal interest in natural product in drug discovery.

    Diabetes is a common metabolic disorder characterized by abnormaly increased plasma glucose levels. Postprandial hyperglycemia plays an essential role in development of type-2 diabetes. Inhibitors of carbohydrate-hydrolyzing enzymes (such as α-glucosidase and α-amylase) offer an effective strategy to regulate/prevent hyperglycemia by controling starch breakdown. Natural α-amylase and α-glucosidase inhibitors, as wel as antioxidants from plant-based sources, offer a source of dietary ingredients that affect human physiological function in order to treat diabetes. Several research studies have investigated the effectiveness of plant-based inhibitors of α-amylase and α-glucosidase, as wel as their antioxidant activity. The aim of this review is to summarize the antidiabetic and antioxidant properties of several medicinal plants around the world. Half inhibitory concentration (IC50,for enzyme suppression) and half effective concentration (EC50, for antioxidant activity) values of less than 500 μg/mL were deifned as the most potent plant-based inhibitors (in vitro) and are expected to provide interesting candidates for herbal treatment of diabetes, as foods, supplements, or reifned drugs.

    Full Text Available This study investigated the cytotoxicity of 55 species of plants. Each plant was rated as medicinal, or nonmedicinal based on the existing literature. About 79% of the medicinal plants showed some cytotoxicity, while 75% of the nonmedicinal plants showed bioactivity. It appears that Asteraceae, Labiatae, Pinaceae, and Chenopodiaceae were particularly active against human cervical cancer cells. Based on the literature, only three of the 55 plants have been significantly investigated for cytotoxicity. It is clear that there is much toxicological work yet to be done with both medicinal and nonmedicinal plants.

    Toxicity of phytochemicals, plant-based extracts and dietary supplements, and medicinal plants in general, is of medical importance and must be considered in phytotherapy and other plant uses. We show in this report how general database analyses can provide a quantitative assessment of research and evidence related to toxicity of medicinal plants or specific phytochemicals. As examples, several medicinal plants are analyzed for their relation to nephrotoxicity and hepatotoxicity. The results of analyses in different databases are similar, and reveal the two best-established toxic effects among the group of plants that were examined: nephrotoxicity of Aristolochia fangchi and hepatotoxicity of Larrea tridentata.

    Context Insects can be the cause of major ecological problems; they can transmit microbes and parasites that affect humans, and damage food crops, trees, and homes. The total economic cost of insect-related damage and disease is immeasurable. In traditional Iranian medicine (TIM), several medicinal plants have been identified as insecticides or insect repellents, but many of them are still unknown. Therefore, the aim of this study was to review the insecticidal or insect repellent activity of certain medicinal plants described in TIM. Evidence Acquisition Information about medicinal plants proposed as insecticides and insect repellents in the TIM was collected from the TIM literature, and searched in modern medical databases to find studies that confirmed their efficacy. Results Modern investigations have supported the claims of the insecticidal activity of several plants, including Allium sativum, Artemisia absinthium, Citrullus colocynthis, Laurus nobilis, Mentha pulegium, Myrtus communis, Nerium oleander, Ocimum basilicum, and Origanum majorana. However, in the cases of plants like Iris florentina and Malva sylvestris, there is not enough evidence in modern medicine to prove their effectiveness with regard to their insecticidal and insect repellent activities. Conclusions This study confirmed the Iranian traditional medicine claims of the insecticidal and insect repellent activity of certain plants. Further pharmacological and clinical studies are recommended to evaluate the overall efficacy and possible mechanisms underlying these herbs. PMID:27186389

    Medicinal plants have played an important role in treating and preventing a variety of diseases throughout the world. Metabolic syndrome had become a global epidemic, defined as a cluster of three of five criteria: insulin resistance and glucose intolerance, abdominal obesity, hypertension, low high-density cholesterol, and hypertriglyceridemia. The current review focuses on Indian medicinal plant drugs and plants used in the treatment of diabetes and hyperlipidemia. Though there are various approaches to reduce the ill-effects of diabetes and hyperlipidemia and its secondary complications, plant-based drugs are preferred due to lesser side effects and low cost. The current review focuses on twenty-three medicinal plants used in the treatment of Diabetes mellitus and nine medicinal plants used in the treatment of hyperlipidemia. The wealth of knowledge on medicinal plants points to a great potential for research and the discovery of new drugs to fight diseases, including diabetes and hyperlipidemia.

Methods:Antioxidant activity of extracts was evaluated in terms of radical scavenging potential (2,2-diphenyl-1-picrylhydrazyl) and β-carotene bleaching assay. Total phenolic contents and flavonoid contents were also measured. Antimicrobial activity of these plants was examined against Bacillus subtilis, Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa and Candida albicans. Results:The values of IC50 ranged from 4.30 μg/mL to 486.6 μg/mL for the DPPH method, while total antioxidant activity using β-carotene/linoleic acid bleaching assay ranged from 17.03%to 86.13%. It was found that Pistacia lentiscus showed the highest antioxidant capacities using DPPH assay (IC50=4.30 μg/mL), while Populus trimula, Origanum glandulosum, Centaurea calcitrapa, Sysimbrium officinalis and Rhamnus alaternus showed the highest percent of total antioxidant activity inβ-carotene/linoleic acid bleaching assay. Total phenolic and flavonoid contents ranged from 3.96 to 259.65 mg GAE/g extract and from 1.13 to 26.84 mg QE/g extract, respectively. The most interesting antimicrobial activity was obtained from Sysimbrium officinalis, Rhamnus alaternus, Origanum glandulosum, Cupressus sempervirens, Pinus halipensis and Centaurea calcitrapa. Conclusions:The results indicated that the plants tested may be potential sources for isolation of natural antioxidant and antimicrobial compounds.

    Full Text Available Abstract Background An efficient method for the identification of medicinal plant products is now a priority as the global demand increases. This study aims to develop a DNA-based method for the identification and authentication of plant species that can be implemented in the industry to aid compliance with regulations, based upon the economically important Hypericum perforatum L. (St John’s Wort or Guan ye Lian Qiao. Methods The ITS regions of several Hypericum species were analysed to identify the most divergent regions and PCR primers were designed to anneal specifically to these regions in the different Hypericum species. Candidate primers were selected such that the amplicon produced by each species-specific reaction differed in size. The use of fluorescently labelled primers enabled these products to be resolved by capillary electrophoresis. Results Four closely related Hypericum species were detected simultaneously and independently in one reaction. Each species could be identified individually and in any combination. The introduction of three more closely related species to the test had no effect on the results. Highly processed commercial plant material was identified, despite the potential complications of DNA degradation in such samples. Conclusion This technique can detect the presence of an expected plant material and adulterant materials in one reaction. The method could be simply applied to other medicinal plants and their problem adulterants.

    CRISPR/Cas9 is a powerful genome editing tool that has been extensively used in model plants and crops, such as Arabidopsis thaliana, rice, wheat, and soybean. Here, we report the use of CRISPR/Cas9 to precisely knock out the committed diterpene synthase gene (SmCPS1) involved in tanshinone biosynthesis in Salvia miltiorrhiza, a traditional Chinese medicinal herb with significant pharmacological activities, such as vasorelaxation, protection against ischemia-reperfusion injury, and antiarrhythmic effects. Three homozygous and eight chimeric mutants were obtained from 26 independent transgenic hairy root lines by Agrobacterium rhizogenes-mediated transformation. The metabolomic analysis based on LC-qTOF-MS and Q-TRAP-LC-MS/MS revealed that tanshinones, especially cryptotanshinone, tanshinone IIA and tanshinone I, are completely missing in homozygous mutants, without influencing other phenolic acid metabolites. By contrast, tanshinones are decreased but still detectable in chimeric mutants, which is similar to a previously-reported an RNAi study of SmCPS1. These results demonstrate that Agrobacterium rhizogenes- mediated transformation using CRISPR/Cas9 is a simple and efficient genome editing tool in S. miltiorrhiza, thus paving the way for large-scale genome editing in S. miltiorrhiza, which is important for pathway elucidation of secondary metabolites, quality improvement, and yield increases for this valuable traditional Chinese medicinal herb.

    DNA barcoding is a technique in which species identification and discovery are performed by using short and standard fragments of DNA sequences. In this study, eleven species of Paris, including seven varieties, were sampled. Five chloroplast sequences, psbA-trnH, rpoB, rpoC1, rbcL, matK, and one nuclear marker, the second internal transcribed spacer (ITS2) of ribosomal DNA, were amplified and sequenced. The PCR amplification and sequencing efficiency, intra- and inter-specific divergence and barcoding gap were used to evaluate different loci, and the identification efficiency was assessed using BLAST1 and Nearest Distance methods. The ITS2 sequences in the studied samples of Paris were amplified and sequenced successfully using primers designed by our group, while matK showed low level in the amplification and psbA-trnH was difficult for sequencing because of over 800 bp and poly (A) structure. Analysis of the intra- and inter-specific divergence and barcoding gap showed ITS2 was superior to other loci. The ITS2 showed a much higher percentage of success (100%) in identification than other five loci, none of which indicated more than 50% except matK (52.9%). The 2-locus combination of rbcL+matK didn't improve ability of authentication. In addition, the rate of successful identification with ITS2 kept 100% when the samples were expanded to 67 samples of 29 species. In conclusion, ITS2 can be used to correctly identify medicinal plants of Paris, and it will be a potential DNA barcode for identifying medicinal plants of other taxa.

    From the last several years, there has been an increasing interest in plant-associated bacteria commonly referred to as endophytes that reside asymptomatically in the internal plant tissues. This interest peaked since the last two decades due to the recognition that endophytes within medicinal plants have the capability to mimic and produce the bioactive metabolites of the host plant. A number of medicinal plants have been used for centuries by the people of South Asia to cure various diseases and this has led to abundant usage experience. Relating to prior ethanopharmacological experiences, scientists have searched for medicinal plants that could be valued sources for endophytes yielding novel metabolites of pharmaceutical importance. This review is therefore an effort to encompass the most recent efforts in the exploration of medicinal plants of South Asia and their endophytes.

    The scorpionic and ophidian envenomations are a serious public health problem in Tunisia especially in Southeastern regions. In these regions Artemisia campestris L is a plant well known which has a very important place in traditional medicine for its effectiveness against alleged venom of scorpions and snakes. In this work, we tested for the first time, the anti-venomous activity of Artemisia campestris L against the scorpion Androctonus australis garzonii and the viper Macrovipera lebetina venoms. Assays were conducted by fixing the dose of extract to3 mg/mouse while doses of venom are variable. The leaves of Artemisia campestris L were extracted by various organic solvents (Ether of oil, ethyl acetate, methanol and ethanol) and each extract was tested for its venom neutralizing capacity. For the ethanolic extract, a significant activity with respect to the venoms of scorpion Androctonus australis garzonii (Aag), was detected. Similarly, a significant neutralizing activity against the venom of a viper Macrovipera lebetina (Ml), was obtained with the dichloromethane extract. These results suggest the presence of two different type of chemical components in this plant: those neutralizing the venom of scorpion are soluble in ethanol whereas those neutralizing the venom of viper are soluble in dichloromethane.

    Full Text Available Neglected tropical diseases (NTDs affect over one billion people all over the world. These diseases are classified as neglected because they impact populations in areas with poor financial conditions and hence do not attract sufficient research investment. Human African Trypanosomiasis (HAT or sleeping sickness, caused by the parasite Trypanosoma brucei, is one of the NTDs. The current therapeutic interventions for T. brucei infections often have toxic side effects or require hospitalization so that they are not available in the rural environments where HAT occurs. Furthermore, parasite resistance is increasing, so that there is an urgent need to identify novel lead compounds against this infection. Recognizing the wide structural diversity of natural products, we desired to explore and identify novel antitrypanosomal chemotypes from a collection of natural products obtained from plants. In this study, 440 pure compounds from various medicinal plants were tested against T. brucei by in a screening using whole cell in vitro assays. As the result, twenty-two phenolic compounds exhibited potent activity against cultures of T. brucei. Among them, eight compounds—4, 7, 11, 14, 15, 18, 20, and 21—showed inhibitory activity against T. brucei, with IC50 values below 5 µM, ranging from 0.52 to 4.70 μM. Based on these results, we attempt to establish some general trends with respect to structure-activity relationships, which indicate that further investigation and optimization of these derivatives might enable the preparation of potentially useful compounds for treating HAT.

    Full Text Available ABSTRACT Haplophyllum telephioides Boiss., Rutaceae, is an endemic herb which generally grows at the steppe region in Central Turkey. Its aerial parts in flowering stage are used by local people against influenza virus due to its antimicrobial effect. The main purpose of this study was to examine the morphology, anatomy and histology of the vegetative and reproductive organs of the H. telephioides, which are used in popular medicine, thereby, contributing to the pharmacognostic evaluation of the species. The species was studied morphologically in detail. New morphological features were described for them, such as the dimension of leaf, sepal and fruit, size of filament, anther and pistil, and diameter of the ovary. In addition, some deviating features were found in relation to previous published descriptions for the species, such as plant height and petal length. The anatomy of plant parts such as stem, leaf, sepal, petal, filament and pistil, were studied using light microscopy and scanning electron microscopy. Stem has incipient secondary growth. The leaf is amphistomatic and the mesophyll is equifacial. Stomata are anomocytic and sunken. In micromorphological studies, it is determined that the leaf is coated by a thick cuticle and above epicuticular wax. Schizogenous glands were found in all vegetative and reproductive organs. The structural features herein found can assist the diagnosis of H. telephioides.

    Infertility is defined as inability of a sexually active couple to conceive after 1 year of regular intercourse without contraception. Male factors account for 20%-50% of cases of infertility. The aim of this study was to review medicinal plants that proposed to improve sperm abnormalities in traditional Persian medicine. For this purpose, PubMed, Scopus, GoogleScholar and Cochrane library were explored for medicinal plants used in traditional Persian medicine for sperm abnormalities to obtain studies giving any evidence for their efficacy and pharmacological mechanisms related to male infertility. Data were collected for the years 1966 to March 2015. For some of them, including Chlorophytum borivilianum, Crocus sativus, Nigella sativa, Sesamum indicum, Tribulus terrestris, Mucuna pruriens and Withania somnifera, more reliable evidence was found. The mechanisms involved in the beneficial effects of medicinal plants in sperm abnormalities are antioxidant, anti-inflammatory, anti-oedematous and venotonic activity as well as containing precursors for sperm production and increasing blood testosterone level. Various phytochemical categories including saponins, phytosterols, carotenoids, oxygenated volatile compounds, phenolic compounds and alkaloids seem to be responsible for these beneficial effects. Further studies are recommended for obtaining more conclusive results about the efficacy and safety of the mentioned medicinal plants.

    Full Text Available In response to increased popularity and greater demand for medicinal plants, a number of conservation groups are recommending that wild medicinal plants be brought into cultivation systems. We collected four medicinal herbs Cichorium pumilum, Eryngium creticum, Pistacia palaestina and Teucrium polium used in traditional Arab medicine for greenhouse cultivation to assess the effects of different fertilization regimes on their growth and antioxidant activity. Wild seedlings were collected and fertilized with either 100% Hoagland solution, 50% Hoagland solution, 20% Hoagland solution or irrigated with tap water. Plant height was measured and the number of green leaves and branches counted weekly. Thereafter, the aboveground parts of plants were harvested for preparing a water-soluble powder extracts of which antioxidant activity was measured by their ability to suppress the oxidation of β-carotene. Of the fertilization regimes, we found either 20 or 50% Hoagland solution produced the most consistent response of the plant growth parameters. All powders prepared from the four wild growing plants inhibited oxidation of β-carotene. Increasing the amount of fertilizer caused a significant concentration-dependent increase in antioxidant activity of the cultivated T. polium compared with the wild type. In contrast, increasing the amount of fertilizer caused a significant concentration-dependent reduction in the antioxidant activity of powders prepared from the cultivated E. creticum when compared with wild plants. Our results showed that cultivation success should not rely solely on parameters of growth but should incorporate assessment related to indices of therapeutic potential.

    Full Text Available Medicinal plants are sources of health-promoting substances, including phytochemicals and phytoalexins that comprise polyphenols, flavonoids, carotenoids, vitamins A, C, E and several other constituents. Many studies have indicated that medicinal plants have been used to treat human diseases for thousands of years owing to their antimicrobial and antioxidant activities. Medicinal plants reduce the oxidative stress in cells and prevent cancer, cardiovascular and inflammatory diseases, neurodegenerative and digestive system disorders. These potential beneficial effects have been attributed to the presence of bioactive compounds that show antioxidant properties by acting as free radical scavengers or metal chelators, reducing the reactions that produce reactive oxygen and nitrogen species (ROS/RNS. Considering the importance of medicinal plants in terms of their beneficial health effects, some of the medicinally important plants grown in Turkey are covered in this review with respect to their antioxidant potential and phytochemical profile.

    Medicinal plants are globally valuable sources of herbal products, and they are disappearing at a high speed. This article reviews global trends, developments and prospects for the strategies and methodologies concerning the conservation and sustainable use of medicinal plant resources to provide a reliable reference for the conservation and sustainable use of medicinal plants. We emphasized that both conservation strategies (e.g. in situ and ex situ conservation and cultivation practices) and resource management (e.g. good agricultural practices and sustainable use solutions) should be adequately taken into account for the sustainable use of medicinal plant resources. We recommend that biotechnical approaches (e.g. tissue culture, micropropagation, synthetic seed technology, and molecular marker-based approaches) should be applied to improve yield and modify the potency of medicinal plants.

    Cholangiocarcinoma (CCA) is one of the most common causes of cancer-associated mortality in Thailand. Certain phytochemicals have been demonstrated to modulate apoptotic signaling pathways, which may be targeted for the prevention and treatment of cancer. Therefore, the aim of the present study was to investigate the effect of specific medicinal plants on the inhibition of CCA cell proliferation, and to identify the molecular mechanisms underlying this. A WST-1 cell proliferation assay was performed using an RMCCA1 cell line, and apoptotic signaling pathways were also investigated using a PathScan Stress and Apoptosis Signaling Antibody Array Kit. The cell proliferation assay indicated that extracts from the Phyllanthus emblica fruit pulp (PEf), Phyllanthus emblica seed (PEs), Terminalia chebula fruit pulp (TCf), Terminalia chebula seed (TCs), Areca catechu seed (ACs), Curcuma longa (CL) and Moringa oleifera seed (MOs) exerted anti-proliferative activity in RMCCA1 cells. In addition, the PathScan assay revealed that certain pro-apoptotic molecules, including caspase-3, poly (ADP-ribose) polymerase, checkpoint kinase 2 and tumor protein 53, exhibited increased activity in RMCCA1 cells treated with the aforementioned selected plant extracts, with the exception of PEf. The mitogen-activated protein kinase (MAPK) pathways (including ERK1/2 and p38 MAPK) expression level was significantly increased in RMCCA1 cells pre-treated with extracts of PEs, TCf, CL and MOs. The activation of protein kinase B (Akt) was significantly demonstrated in RMCCA1 cells pre-treated with extracts of TCf, ACs and MOs. In summary, the present study demonstrated that extracts of PEs, TCf, TCs, ACs, CL and MOs exhibited anti-proliferative effects in CCA cells by inducing pro-apoptotic signals and modulating signal transduction molecules. Further studies in vivo are required to demonstrate the potential applications of specific plant extracts for the treatment of human cancer.

    Angiogenesis plays an important role in tumor formation and proliferation. The development of anti-angiogenic agents to block new blood vessel growth will inhibit metastasis and induce apoptosis of the cancer cells. Nine medicinal plants, Strobilanthes crispus, Phyllanthus niruri, Phyllanthus pulcher, Phyllanthus urinaria, Ailanthus malabarica, Irvingia malayana, Smilax myosotiflora, Tinospora crispa and blumea balsamifera were screened for anti-angiogenic properties using the rat aortic ring assay. Of these, the methanol extracts of Phyllanthus species and Irvingia malayana exhibited the highest activity. At 100 microg/mL, P. pulcher, P. niruri, P. urinaria and I. malayana recorded an inhibition of 78.8 %, 59.5 %, 56.7 % and 46.4 %, respectively, against rat aortic vascular growth. Their activities were further investigated by the tube formation assay involving human umbilical vein endothelial cells (HUVEC) on Matrigel. I. malayana, P. niruri and P. urinaria showed a significant decrease of 45.5, 37.9 and 35.6 %, respectively, whilst P. pulcher showed a much lower decrease of 15.5 % when compared with that of the rat aortic ring assay. All the plant extracts were evaluated for cytotoxicity on a panel of human cancer cell lines using the MTT assay. None of them displayed acute cytotoxicity. The HPLC of P. niruri, P. urinaria and P. pulcher indicated the extracts contained some identical chromatographic peaks of lignans. Further fractionation of I. malayana yielded betulinic acid reported in this plant for the first time and at 100 microg/mL it exhibited a 67.3 % inhibition of vessel outgrowth and 46.5 % inhibition of tube formation.

    2006-09-01

    Full Text Available The importance of the medicinal plants sector can be gauged from the fact that herbal medicines serve the healthcare needs of about 80 per cent of the world's population. India, with approximately eight percent of world's biodiversity including plant genetic diversity with medicinal properties, has the potential of becoming a major global player in market for medicinal plants-based herbal formulations and products. However, prior to establishment of Medicinal Plants Board, there was no nodal agency to look into medicinal plants as an economic 'sector' and different organisations dealt with different aspects of medicinal plants without any clear cut focus and coordination. This lack of co-ordination led to critical research gaps relating to socio-economic and policy aspects of medicinal plants. At the same time, absence of formal marketing linkages and effective buy-back arrangements hindered the development of medicinal plants sector. Developing appropriate varieties for cultivation which could ensure uniform quality and continuous supply of raw material for processing industry would not only meet the industry demand but also halt the degradation of natural resource base. To capitalize on expanding opportunities in the international market, we need to focus on scientific methods of cultivation, harvesting, processing, grading, transport, storage, labeling and marketing practices involved in the entire supply chain for medicinal plants. Policy and institutional issues particularly related to co-ordination among various stake holders are one of the major constraints faced by this sector. Species- specific and socio-economic environment specific research would be helpful for identification of an optimal institutional framework to take care of needs of various stakeholders and also cater to social needs without adverse implications for equity and environment.

    2013-11-01

    Since centuries, natural compounds from plants, animals and microorganisms were used in medicinal traditions to treat various diseases without a solid scientific basis. Recent studies have shown that plants that were used or are still used in the medieval European medicine are able to provide relieve for many diseases including cancer. Here we summarize impact and effect of selected purified active natural compounds from plants used in European medieval medicinal traditions on cancer hallmarks and enabling characteristics identified by Hanahan and Weinberg. The aim of this commentary is to discuss the pharmacological effect of pure compounds originally discovered in plants with therapeutic medieval use. Whereas many reviews deal with Ayurvedic traditions and traditional Chinese medicine, to our knowledge, the molecular basis of European medieval medicinal approaches are much less documented.

    2011-11-01

    The use of traditional/complementary/alternate medicines (TCAMs) in HIV/AIDS patients who reside in Southern Africa is quite common. Those who use TCAMs in addition to antiretroviral (ARV) treatment may be at risk of experiencing clinically significant pharmacokinetic (PK) interactions, particularly between the TCAMs and the protease inhibitors (PIs) and non-nucleoside reverse transcriptase inhibitors (NNRTIs). Mechanisms of PK interactions include alterations to the normal functioning of drug efflux transporters, such as P-gp and/or CYP isoenzymes, such a CYP3A4 that mediate the absorption and elimination of drugs in the small intestine and liver. Specific mechanisms include inhibition and activation of these proteins and induction via the pregnane X receptor (PXR). Several clinical studies and case reports involving ARV-herb PK interactions have been reported. St John's Wort, Garlic and Cat's Claw exhibited potentially significant interactions, each with a PI or NNRTI. The potential for these herbs to induce PK interactions with drugs was first identified in reports of in vitro studies. Other in vitro studies have shown that several African traditional medicinal (ATM) plants and extracts may also demonstrate PK interactions with ARVs, through effects on CYP3A4, P-gp and PXR. The most complex effects were exhibited by Hypoxis hemerocallidea, Sutherlandia frutescens, Cyphostemma hildebrandtii, Acacia nilotica, Agauria salicifolia and Elaeodendron buchananii. Despite a high incidence of HIV/AIDs in the African region, only one clinical study, between efavirenz and Hypoxis hemerocallidea has been conducted. However, several issues/concerns still remain to be addressed and thus more studies on ATMs are warranted in order for more meaningful data to be generated and the true potential for such interactions to be determined.

    Unorganized collections and over exploitation of naturally occurring medicinal plant Bacopa monniera is leading to rapid depletion of germplasm and is posing a great threat to its survival in natural habitats. The species has already been listed in the list of highly threatened plants of India. This calls for micropropagation based multiplication of potential accessions and understanding of their mycorrhizal associations for obtaining plants with enhanced secondary metabolite contents. The co-cultivation of B. monniera with axenically cultivated root endophyte Piriformospora indica resulted in growth promotion, increase in bacoside content, antioxidant activity and nuclear hypertrophy of this medicinal plant.

(bittersweet is a medicinal plant that has been used to treat skin diseases, warts, tumors, felons, arthritis, rheumatism, bronchial congestion, heart ailments, ulcerative colitis, eye inflammations, jaundice and pneumonia. A reliable in vitro culture protocol for bittersweet was established. Explants (leaf and petiole segments were cultured on Murashige and Skoog minimal organics (MSMO medium with various plant growth regulator combinations. Leaf explants formed more shoots than petiole explants. Plant regeneration was observed through indirect organogenesis with both explants. Best shoot proliferation was obtained from leaf explants with 3 mg/l BA (benzyladenine and 0.5 mg/l IAA (indole-3-acetic acid. Regenerated shoots were transferred to rooting media containing different levels of IAA (indole-3-acetic acid, IBA (indole-3-butyric acid, NAA (naphthalene acetic acid or 2,4-D (2,4 dichlorophenoxyacetic acid. Most shoots developed roots on medium with 0.5 mg/l IBA. Rooted explants were transferred to vermiculate in Magenta containers for acclimatization and after 2 weeks, they were planted in plastic pots containing potting soil and maintained in the plant growth room.

    Full Text Available Medicinal plants (MPs are an important component of non-timber forest products (NTFPs, which are traditionally used in healthcare and source of livelihood all over the world. In an over-populated country like Bangladesh, the pressure on natural forests is immense; thus the cultivation of MPs can significantly contribute towards improving the livelihood of poor people, reducing the pressure on natural forests and enhancing biological diversity. Notwithstanding the growing recognition of its importance and economic and ecological potential, there has been little research on MPs, especially the cultivation, management and marketing aspects, in Bangladesh. Based on extensive fieldwork in a northern district of Bangladesh, this study explores various aspects of the cultivation, management and marketing of MPs. How collective efforts have brought economic and social benefits to communities was also examined in this study. It assesses the major processes and elements of management, identifies key problems and challenges and indicates ways of maximizing the potential of this important sector. The issues covered in this research include: farmers ’ perceptions and experiences; existing research and policy-making processes related to the MP sector; constraining factors (such as lack of processing technology, inadequate transportation, logistics, financial and storage infrastructure, lack of institutional capacity; markets, finance and networking; land use; pattern of livelihood and value chain issue.

    Medicinal plants are registered on the French Pharmacopoeia in its successive editions, the first dated 1818. The edition which is currently in force, the XIth (2012), comprises two plant lists drawn up by a working group of experts belonging to the ANSM: List A (medicinal plants traditionally used [365 plants]) and list B (medicinal plants with the ratio benefit/risk's evaluation negative [123 plants]). Moreover, a list of medicinal plants with non exclusive therapeutic use has been established. This last list is composed of 147 plants which are thus liberated from the pharmaceutical monopoly, in application of decrees n(o) 2008-839 and 2008-841 dated August 22nd 2008. Medicinal plants are a matter, in France, from pharmaceutical monopoly, which means that they can only be dispensed to public in pharmacy, according to article L. 4211-1/5° of the Public Health Code, except however for a certain number of plants "liberated" from this monopoly. Nevertheless, besides officinal pharmacists, herbalists who obtained their diploma as far as 1941, were habilitated to deliver medicinal plants, even non "liberated", on condition that they are not registered on a list of venomous substances nor classified among the stupefacients, according to the article L. 4211-7 of Public Health Code. Concerning plants for herbal teas, which should be differentiated from herbal teas classified among the herbal medicines, they can be delivered in mixtures form, which are considered as officinal preparations, according to the new French Pharmacopoeia monography of August 1st 2013.

    Full Text Available Abstract Background The Eastern Highlands area of Papua New Guinea (PNG has a rich tradition of medicinal plant use. However, rapid modernization is resulting in the loss of independent language traditions and consequently a loss of individuals knowledgeable in medicinal plant use. This report represents a program to document and preserve traditional knowledge concerning medicinal plant use in PNG. This report documents and compares traditional plant use in the Eastern Highlands districts of Unggai-Bena, Okapa, and Obura-Wonenara, and puts these new records in context of previously documented PNG medicinal plant use. Methods This manuscript is an annotated combination of Traditional Medicines survey reports generated by UPNG trainees using a survey questionnaire titled “Information sheet on traditional herbal reparations and medicinal plants of PNG”. The Traditional Medicines survey project is supported by WHO, US NIH and PNG governmental health care initiatives and funding. Results Overall, after “poisoning” (synonymous with “magic” the most commonly recorded ailments addressed by medicinal plant use were pain, gynecological disease, gastrointestinal maladies, anemia or malnutrition and malaria. However, the recorded indications for plant use varied widely amongst the different survey locations. Unlike many areas of PNG, mixing of ingredients was the most common mode of preparation recorded, except for two areas where the consumption of fresh plant material was more common. Throughout the Eastern Highlands oral administration was most common, with topical application second. Overall, leaves were most commonly used in the preparations of the healers interviewed, followed by bark and stems. Several new medicinal uses of plants were also documented. Conclusions Collaboration between the WHO, UPNG and the PNG Department of Health initiated Traditional Medicine survey program in order to preserve traditional knowledge concerning

    Arsenic (As) is a widespread environmental and food chain contaminant and class I, non-threshold carcinogen. Plants accumulate As due to ionic mimicry that is of importance as a measure of phytoremediation but of concern due to the use of plants in alternative medicine. The present study investigated As accumulation in native plants including some medicinal plants, from three districts [Chinsurah (Hoogly), Porbosthali (Bardhman), and Birnagar (Nadia)] of West Bengal, India, having a history of As pollution. A site-specific response was observed for Specific Arsenic Uptake (SAU; mg kg(-1) dw) in total number of 13 (8 aquatic and 5 terrestrial) collected plants. SAU was higher in aquatic plants (5-60 mg kg(-1) dw) than in terrestrial species (4-19 mg kg(-1) dw). The level of As was lower in medicinal plants (MPs) than in non-medicinal plants, however it was still beyond the WHO permissible limit (1 mg kg(-1) dw). The concentration of other elements (Cu, Zn, Se, and Pb) was found to be within prescribed limits in medicinal plants (MP). Among the aquatic plants, Marsilea showed the highest SAU (avg. 45 mg kg(-1) dw), however, transfer factor (TF) of As was the maximum in Centella asiatica (MP, avg. 1). Among the terrestrial plants, the maximum SAU and TF were demonstrated by Alternanthera ficoidea (avg. 15) and Phyllanthus amarus (MP, avg. 1.27), respectively. In conclusion, the direct use of MP or their by products for humans should not be practiced without proper regulation. In other way, one fern species (Marsilea) and some aquatic plants (Eichhornia crassipes and Cyperus difformis) might be suitable candidates for As phytoremediation of paddy fields.

    B Nandagopal

    2011-01-01

    Full Text Available Indian medicinal plants are now recognized to have great potential for preparing clinically useful drugs that could even be used by allopathic physicians. Traditionally, practitioners of Indian medicine have used plant products in powder, syrup or lotion forms, without identification, quantification and dose regulation, unlike their allopathic counterparts. The present review explores the immense potential of the demonstrated effect of Indian medicinal plants on microbes, viruses and parasites. In the present context, with the available talent in the country like pharmaceutical chemists, microbiologists, biotechnologists and interested allopathic physicians, significant national effort towards identification of an "active principle" of Indian medicinal plants to treat human and animal infections should be a priority.

    The continuous need for new compounds with important medicinal activities has lead to the identification and characterization of various plant-derived natural products. As a part of this program, we studied the saponin production from two tropical medicinal plants Maesa argentea and M. lanceolata and evaluated several treatments to enhance their saponin production. In this experiment, we present the analyses of saponin production from greenhouse grown plants by means of TLC and HPLC-MS. We observed that the content of saponin from these plants varied depending on organ and physiological age of the plants. In addition, the impact of elicitors on saponin accumulation on in vitro grown plants was analyzed using TLC. The production of saponin was very stable and not affected by treatment with methyl jasmonate, and salicylic acid. In conclusion, Maesa saponins are constitutively produced in plants and the level of these compounds in plants is mainly affected by the developmental or physiological stage.

    Investigations for anti-inflammatory potential and categorization of Sudanese medicinal plants according to their potency. Anti-inflammatory effect of plants' extracts of 17 genera were studied using the carrageenan induced inflammation in rats' paws. The plant extracts were obtained using methanol and dichloromethane as solvent and administered intra peritoneally at the concentration of 2g/kg body weight. The results obtained in this experiment strongly support and validate the traditional uses of these Sudanese medicinal plants to treat various inflammatory diseases. 63.9% of plants extracts showed marked inhibition of inflammation induced by carrageenan (78.3% out of this percentage represented by methanolic extract), 27.8% showed no activity and 8.3% enhanced the carrageenan induced inflammation. The anti-inflammatory effect of many of these plants has not been reported previously, yet they have been extensively used in Sudanese folkloric medicine. The result of this study justify the traditional medicinal use of the evaluated plants species in treating inflammatory disorders and helped in categorizing the investigated plants into most useful, moderately useful and least useful category for inflammatory diseases. Out of the 17 investigated plant species 05 belongs to most useful and 06 belongs to moderately useful category. However, toxicity studies are required to prove the safety of these plant materials.

    Qualitative-quantitative structure of plant pigments in wild plants Malva silvestrs L. and Malva moschata L. (Malvaceae), which were collected in 20 locations in Sarajevo area and surroundings, was tested during spring and summer in 2003. Acetone extracts of both categories were made and rising paper-chromatography done for the purpose of qualitative analysis. Quantitative analysis was done by spectrophotometry. Chlorophyll a, chlorophyll b and xanthophylls presence was confirmed by separation of pigments from acetone extract of these plant species. Spectrophotometric analysis of acetone extracts showed these results (given in mg/L): chlorophyll a 2,386, chlorophyll b 0,332 and carrotenoides 1,037. Data given in mg/g dry substance are: chlorophyll a 1,193x10(-2), chlorophyll b 1,66x10(-3), and carrotenoides 5,185x10(-3). Pigments structure (in mg/L) in species Malva moschata is 1,6 for chlorophyll; 1,419 for chlorophyll b; and 0,364 for carrotenoides. Data given in mg/g are: chlorophyll a 8x10(-3), chlorophyll b 7,09x10(-3), and carrotenoides 1,82x10(-3). Considering that species Malva moschata L. grows on ecologically clear soils as opposed to well-known medicinal species Malva sylvestris L., and considering the production of phytomass, phytochemical structure and pharmacological influence it can be considered very medical and be given advantage over this wider spread category.

    Herbal medicine, the backbone of traditional medicine, has played an important role in human health and welfare for a long period. Traditional therapeutic approaches of regional significance are found in Africa, South and Central America, China, India, Tibet, Indonesia, and the Pacific Islands. The considerable scientific significance and commercial potential of traditional medicines have resulted in increased international attention and global market demands for herbal medicines, especially Chinese herbal medicines. Herbal medicines currently are the primary form of health care for the poor in the developing countries, and also are widely used as a supplement or substitute for conventional drugs in developed countries. These traditional medicines have a pivotal role in the treatment of various ailments and more than 50% of drugs used in Western pharmacopoeia are isolated from herbs or derived from modifications of chemicals found in plants. Herbal medicines usually contain a complex mixture of various bioactive molecules, which make its standardization complicated, and there is little information about all compounds responsible for pharmacological activity. Several research papers have been published that claim pharmacological activity of herbal medicines but few are discussing the role of the exact phytoconstituent. Understanding the pharmacokinetic profile of such phytoconstituents is essential. Although there are research papers that deal with pharmacokinetic properties of phytoconstituents, there are a number of phytoconstituents yet to be explored for their kinetic properties. This article reviews the pharmacokinetic profile of 50 different therapeutically effective traditional medicinal plants from the year 2003 onward.

    Medicinal plants are used worldwide to treat a variety of ailments. Due to the provenance of medicinal plants, they are subjected to contamination by moulds, which may be responsible for spoilage and production of mycotoxins. The investigation was designed to throw light on mycological and mycotoxicological status of some medicinal plants from Pakistan and the result showed 30 % and 26.7 % samples were contaminated with aflatoxins and ochratoxin A, respectively. Mould contamination was present in 90 % samples, of which 70 % exceeded the permissible limits. Opium poppy, licorice root, and Indian rennet were most contaminated samples. The predominant moulds found were Aspergillus flavus, Aspergillus niger, Aspergillus parasiticus, and Penicillium spp. and 31 % of the 47 isolates tested were found to be toxigenic. The findings indicate that the contamination in the medicinal plants may contribute to adverse human health problems. This information would prove helpful for regulatory agencies to establish limits for these contaminants in medicinal plants and will explore ways for export of herbal products to countries where more stringent permissible limits of mycotoxins exist. The study is first of its kind in the country reporting natural occurrence of mycotoxins in medicinal plants in Pakistan.

    Full Text Available Abstract Background The evolution and spread of antibiotic resistance, as well as the evolution of new strains of disease causing agents, is of great concern to the global health community. Our ability to effectively treat disease is dependent on the development of new pharmaceuticals, and one potential source of novel drugs is traditional medicine. This study explores the antibacterial properties of plants used in Haudenosaunee traditional medicine. We tested the hypothesis that extracts from Haudenosaunee medicinal plants used to treat symptoms often caused by bacterial infection would show antibacterial properties in laboratory assays, and that these extracts would be more effective against moderately virulent bacteria than less virulent bacteria. Methods After identification and harvesting, a total of 57 different aqueous extractions were made from 15 plant species. Nine plant species were used in Haudenosaunee medicines and six plant species, of which three are native to the region and three are introduced, were not used in traditional medicine. Antibacterial activity against mostly avirulent (Escherichia coli, Streptococcus lactis and moderately virulent (Salmonella typhimurium, Staphylococcus aureus microbes was inferred through replicate disc diffusion assays; and observed and statistically predicted MIC values were determined through replicate serial dilution assays. Results Although there was not complete concordance between the traditional use of Haudenosaunee medicinal plants and antibacterial activity, our data support the hypothesis that the selection and use of these plants to treat disease was not random. In particular, four plant species exhibited antimicrobial properties as expected (Achillea millefolium, Ipomoea pandurata, Hieracium pilosella, and Solidago canadensis, with particularly strong effectiveness against S. typhimurium. In addition, extractions from two of the introduced species (Hesperis matronalis and Rosa

    Diversity of Medicinal Plants among Different Forest-use Types of the Pakistani Himalaya Medicinal plants collected in Himalayan forests play a vital role in the livelihoods of regional rural societies and are also increasingly recognized at the international level. However, these forests are being heavily transformed by logging. Here we ask how forest transformation influences the diversity and composition of medicinal plants in northwestern Pakistan, where we studied old-growth forests, forests degraded by logging, and regrowth forests. First, an approximate map indicating these forest types was established and then 15 study plots per forest type were randomly selected. We found a total of 59 medicinal plant species consisting of herbs and ferns, most of which occurred in the old-growth forest. Species number was lowest in forest degraded by logging and intermediate in regrowth forest. The most valuable economic species, including six Himalayan endemics, occurred almost exclusively in old-growth forest. Species composition and abundance of forest degraded by logging differed markedly from that of old-growth forest, while regrowth forest was more similar to old-growth forest. The density of medicinal plants positively correlated with tree canopy cover in old-growth forest and negatively in degraded forest, which indicates that species adapted to open conditions dominate in logged forest. Thus, old-growth forests are important as refuge for vulnerable endemics. Forest degraded by logging has the lowest diversity of relatively common medicinal plants. Forest regrowth may foster the reappearance of certain medicinal species valuable to local livelihoods and as such promote acceptance of forest expansion and medicinal plants conservation in the region.

    Introduction: The incidence of cardiovascular diseases (CVDs) is very high in human societies and their prevention and treatment are the most important priority in many countries. Hypertension makes an important contribution to the development of CVDs. Objectives: This study aimed to collect the ethno-medicinal knowledge of the traditional healers of Shiraz on medicinal plants used in the treatment of hypertension. Materials and Methods: Ethno-medicinal data were collected from September 2012 to July 2013 through direct interview. Twenty-five healers were interviewed using semi-structured questionnaires and their traditional ethno-medicinal knowledge was recorded. Questionnaires were included apothecary personal information, plant local name, plant parts used, method of preparation, season of harvest and traditional use. Data collected from surveys and interviews were transferred to Microsoft Excel 2007 and analyzed. Results: Analysis of data showed that, 27 medicinal plants from 22 families are used for the treatment of hypertension. The families with most antihypertensive species were Apiaceae (8%), Rosaceae (8%) and Papaveraceae (8%). The most frequently used plant parts were leaves (36%) followed by fruits (30%), aerial part (17%) and branches (7%). The most frequently used preparation method was decoction (95%). Borago officinalis (51.85%), Berberis vulgaris (51.58%) had the highest frequency of mention. Conclusion: The ethno-medicinal survey of medicinal plants recommended by traditional healers for the treatment of hypertension provides new areas of research on the antihypertensive effect of medicinal plants. In the case of safety and effectiveness, they can be refined and processed to produce natural drugs. PMID:27689107

    Plants of the genus Aconitum L. are commonly used in Asia for medicinal purposes. Although they are widely cultivated and marketed, there has been uncertainty about the efficacy of different species, and therefore accurate identification is crucial. To determine the genetic variation among these medicinal plants, the proposed DNA barcode PSBA- TRNH intergenic spacer of 134 individuals from 19 taxa of ACONITUM were sequenced. Among the two most commonly used medicinal ACONITUM species, A. carmichaeli and A. kusnezoffii, sequence inversions were observed. The studied samples were clustered into ten groups according to the sequence alignment and most of the tested Aconitum species could be differentiated by the PSBA -TRNH intergenic spacer.

    Pyrrolizidine alkaloids (PAs) can be hazardous to the health of humans and animals. Although their toxicity has been known for a long time, PA containing plants are still in use in many traditional medicines. Traditional healing systems have become of increasing interest as many people believe that they can be used without any risk and side effects. This also applies to the traditional medicine of Madagascar and the Mascarene island (Mauritius, Reunion, Rodriguez). Recent literature reports have recommended this traditional medicine because of its good efficacy and pharmacological properties. However, several plants are listed there which have already been described to contain toxic PAs or are suspected of containing them.

    Sacred groves are one of the finest examples of traditional in situ conservation practices and act as treasure house of endemic, endangered and rare plants. Endemic species of any geographical region, throw light on the biogeography of the area, areas of extinction and evolution of the flora. Twelve famous sacred groves of north Malabar region of Kerala were selected for study. Studies were aimed at the documentation of floristic diversity with special reference to endemic as well as RET medicinal plants and to know threats to them. Present inventory accounted for a total of 99 endemic angiosperms, of which 28 qualified for RET categories. Their role in germplasm conservation is evident from the fact that not a single plant is common to the groves studied and restriction of 47 endemic plants to any one of the grove. There are 59 endemic plants, of which 18 belong to RET category are in high demand due to their medicinal properties. Medicinal plant diversity varies from a minimum of 65% to a maximum of 91% while that of endemic plants ranges from 11% in Andallur to 18% in Edayilakkad. Present study revealed the endemic plant diversity of these groves and also their role in the conserving germplasms of wild yam, figs, pepper, mango and a variety of endemic medicinal plants. Like other groves of Kerala, these are also facing the threat of extinction from increasing anthropogenic activities and there is an urgent need of complete protection and public awareness for the existence of these near-climax communities.

    Full Text Available Background: The levels of 5 minerals namely; lead, arsenic, mercury, cadmium, and aluminum were assessed in 10 medicinal plants sampled from 5 different geographical locations to determine the effect of location on the plants′ mineral content. Materials and Methods: Atomic absorption spectrophotometry (wet digestion was used for the analyzes, and content of the minerals per sample was expressed as μg/g. The levels of minerals were compared to their limit specification for herbs and daily total intake of these minerals. A two-way analysis of variance, which tends to look at the effect of the location and the medicinal plant itself on the plants mineral content, was used in the statistical analysis. Results: Lead (Pb was present in all plant species examined, except Ocimum gratissimum. One plant exceeded the maximum safety limit for lead. Cadmium was also detected in some of the medicinal plant species (44% whilst majority were below the detection limit (0.002 representing 56%. 40% of the plant species exceeded the limit for cadmium. Mercury and arsenic in all the plant species were below the detection limit (0.001. Significant variation existed in mineral content for the various locations ( P ≤ 0.05. Conclusion: The findings generally suggest the variation in mineral levels for the various locations. Thus, our study has shown that same species of medicinal plants, growing in different environments, accumulates different levels of heavy metals.

    In traditional practices of Ayurvedic and Chinese medicine, numerous plants have been used to treat cognitive disorders, including neurodegenerative diseases such as Alzheimer's disease (AD). An ethnopharmacological approach has provided leads to identifying potential new drugs from plant sources, including those for cognitive disorders. Many drugs currently available in Western medicine were originally isolated from plants, or are derived from templates of compounds isolated from plants. Some anticholinesterase (anti-ChE) alkaloids isolated from plants have been investigated for their potential in the treatment of AD, and are now in clinical use. Galantamine, isolated from several plants including Lycoris radiata Herb., which was used in traditional Chinese medicine (TCM), is licensed in the United Kingdom for the treatment of mild to moderate AD. Various other plant species have shown pharmacological activities relevant to the treatment of cognitive disorders, indicating potential for therapeutic use in disorders such as AD. This article reviews some of the plants and their active constituents that have been used in traditional Ayurvedic medicine and TCM for their reputed cognitive-enhancing or antiageing effects. Plants and their constituents with pharmacological activities that may be relevant for the treatment of cognitive disorders, including enhancement of cholinergic function in the central nervous system (CNS), anti-inflammatory and antioxidant activities, are discussed.

    Full Text Available Abstract Background This study was conducted to identify medicinal plants and spices used for medicine by the community of Beni-Sueif, Upper Egypt. Methods Ethnobotanical data from local people was collected using direct interviews and a semi-structured questionnaire. Results Forty-eight plant species belonging to twenty-seven families and forty-seven genera were encountered during the study. Their botanical and vernacular names, plant parts used and medicinal uses are given. Results of the study were analyzed using two quantitative tools. The factor informant consensus indicated the agreement in the use of plants and the fidelity level indicated the ratio between the number of informants who independently suggested the use of a species for the same major purpose and the total number of informants who mentioned the plant for any use. The results of the factor informant consensus showed that the cardiovascular category has the greatest agreement, followed by the immunological, gastrointestinal and respiratory categories. The most important species according to their fidelity are: Hibiscus sabdariffa L. for the cardiovascular category; Trigonella foenum-graecum L. for the immunological category; Mentha piperita L. for the gastrointestinal category and Pimpinella anisum L. for the respiratory category. Conclusions Medicinal plants are still used for treatment in Beni-Sueif community despite the availability of prescribed medications. Documentation of this ethnomedicinal knowledge is important. Evaluation of pharmacological activity for the promising medicinal plants is suggested.

    2014-01-01

    Full Text Available The impacts of climate change were severe on indigenous medicinal plant species and their dependent communities. The harvesting calendar and picking sites of these species were no longer coinciding and the changes were affecting harvesters’ and cultivators’ abilities to collect and use those species. Secondary sites: road-heads, wastelands, regenerated forests, and so forth, were being prioritized for collection and the nonindigenous medicinal plant species were being increasingly introduced into the medical repertoire as a substitution and to diversify the local medicinal stock. Acceptance and application of nonindigenous species and sites for livelihood and ethnopharmacopoeias with caution were considered as an important adaptation strategy. Findings on species and site specific accounts urged further researches on medicinal plants, ethnomedicine, and their interrelationship with impacts of climate change.

    Several plant species are traditionally used in Brazil to treat various inflammatory diseases. Tumor necrosis factor- (TNF-) α and chemokine (C-C motif) ligand 2 (CCL2) are key inflammatory mediators in diseases like rheumatoid arthritis and atherosclerosis, respectively; nevertheless, only a few extracts have been assayed against these targets. We herein report the effect of 19 plant extracts on TNF-α and CCL2 release by lipopolysaccharide- (LPS-) stimulated THP-1 cells, a human monocytic leukemia cell line, along with their radical scavenging activity on DPPH. The extracts of Caryocar brasiliense, Casearia sylvestris, Coccoloba cereifera, and Terminalia glabrescens inhibited TNF-α production in a concentration-dependent manner. Fractionation of these extracts potentiated the anti-TNF-α effect, which was shown to concentrate in polar fractions, mainly composed by polyphenols. Significant CCL2 inhibition was elicited by Lippia sidoides and Terminalia glabrescens extracts, whose fractionation resulted in highly active low polar fractions. All assayed extracts showed strong radical scavenging activity, but antioxidant activity did not correlate with inhibition of TNF-α or CCL2 production. Our results allowed identifying extracts with selective capacity to block cytokine production; therefore, further purification of these extracts may yield molecules that could be useful in the treatment of chronic inflammatory diseases.

    Full Text Available Herbal medicine is the oldest and still the most widely used system of medicine in the world today and they are made exclusively from plants. However, most of these medicines or drugs are adulterated due to lack of proper identification of the plant samples. Method of checking adulteration of drug plants is the main focus of this study. The identification and authentication of dry samples of some medicinal plants were carried out using anatomical features. Twenty-five (25 plants materials were collected in Ibadan and Ilorin, Nigeria. The plants studied include Azardiracta indica, Newboudia leavis, Polyalthia longifolia, Cymbopogon citratus, Anarcardium occidentalis, Nicotiana tobbaccum, Jatropha curcas, Chromoleana odorata, Mangifera indica, Terminalia catappa, Ocimum gratisimum, Morus messosygia, Morinda lucida, Psidium guajava, Vitellaria paradoxa, Annona senegalensis, Vernonia amygdalina, Gliricidium sepium, Ravoulvia vomitora, Telferia occindentalis Citrus aurantifolia, C. limon, C. paradisi and C. sinensis. Leaf epidermal anatomy of these selected plants showed no major variations in stomatal complex types, frequency, size and shape of stomatal cells, epidermal cell wall and trichomes between fresh and dry samples. The variations that occur were between different species but not within species. Leaf epidermal anatomy, therefore, proved to be a significant tool for resolution of taxonomic confusion of dried samples of these plants.

    Forty-one methanol extracts of 28 indigenous medicinal plant species were tested for their insecticidal bioactivity against cotton whitefly, Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae), adults and second nymphal instars under controlled conditions. This study is within a bioprospection context, in the form of utilizing local plant species as an alternative in sustainable agriculture development. Eighteen and nine plant extracts caused a significant decrease in number of live adult and nymphal whiteflies, respectively, compared to the control. This is the first report for the potential effect on survival of insects for 22 out of 28 tested medicinal plant species. Whole plant extracts of Ranunculus myosuroudes Boiss. and Kotschy (Ranunculaceae),Achillea damascena L. (Asteraceae), and Anthemis hebronica Boiss. and Kotschy (Asteraceae) and leaf extracts of Verbascum leptostychum DC. (Scrophulariaceae) and Heliotropium rotundifolium Boiss. (Borangiaceae) caused both repellent and toxic effects against the adult and second nymphal instars, respectively. Extracts of leaves and stems of Anthemis scariosa Boiss. (Asteraceae) and Calendula palestina Pers. (Asteraceae) were found to be more bioactive against the adult and nymphal instars, respectively, than extracts of other plant parts, such as flowers. Thus, the bioactive extracts of these medicinal plants have the potential to lower whitefly populations in a comprehensive pest management program in local communities, pending cultivation of these medicinal plant species.

    Forty-one methanol extracts of 28 indigenous medicinal plant species were tested for their insecticidal bioactivity against cotton whitefly, Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae), adults and second nymphal instars under controlled conditions. This study is within a bioprospection context, in the form of utilizing local plant species as an alternative in sustainable agriculture development. Eighteen and nine plant extracts caused a significant decrease in number of live adult and nymphal whiteflies, respectively, compared to the control. This is the first report for the potential effect on survival of insects for 22 out of 28 tested medicinal plant species. Whole plant extracts of Ranunculus myosuroudes Boiss. and Kotschy (Ranunculaceae), Achillea damascena L. (Asteraceae), and Anthemis hebronica Boiss. and Kotschy (Asteraceae) and leaf extracts of Verbascum leptostychum DC. (Scrophulariaceae) and Heliotropium rotundifolium Boiss. (Borangiaceae) caused both repellent and toxic effects against the adult and second nymphal instars, respectively. Extracts of leaves and stems of Anthemis scariosa Boiss. (Asteraceae) and Calendula palestina Pers. (Asteraceae) were found to be more bioactive against the adult and nymphal instars, respectively, than extracts of other plant parts, such as flowers. Thus, the bioactive extracts of these medicinal plants have the potential to lower whitefly populations in a comprehensive pest management program in local communities, pending cultivation of these medicinal plant species.

    Northeastern India has high medicinal plant diversity due to variance in topography and physiognomy. We documented the uses of various medicinal plants by the Bengali people of West district and South district of Tripura state for their own health care as well as for domesti-cated animals. Based on semi structured interviews, group discussions and information from local informants, a total of 93 species of medicinal plants of 52 families and 83 genera were documented. These plants were used to treat more than 55 different human diseases and 6 diseases of livestock. Sixty-eight plant species were used singly and the rest were used in combination with other species for therapeutic formulations of various diseases. Leaves of plants were most often used for most of the ethnobotanical preparations. Maximum consensus value of 96% was recorded for Chromolaena odorata (L.) King &H. Rob., and the mini-mum was 15%for Bambusa balcooa Robx. Of the 93 plant species, 75 species showed pharmacological properties. Prospects for augmenting existing knowledge and enhancing the use of traditional medicinal plants are discussed.

    Full Text Available Despite the importance of medicinal plants for the healthcare of local people, the knowledge about medicinal species used in the Pampa biome has been neglected over the years. In this study, an ethnobotanical survey was employed aiming to characterize the species richness and diversity of commercialized medicinal plant species in five cities within the Brazilian Pampa. Additionally, among the listed plants, ten species were selected for in vitro testing of their potential antioxidant activity. A total of 56 plant species belonging to 33 botanical families were listed by the 115 interviewees. No significant difference in commercialized medicinal plant species, and very similar species richness was observed among the cities, indicating that the local knowledge is consistently preserved across the studied cities. According to the biochemical analysis, Sphagneticola trilobata, Malva parviflora and Struthanthus flexicaulis emerged as very promising species for antioxidant activity. Further studies are recommended to advance our knowledge about the richness of medicinal plant species in the Brazilian Pampa, and to assess their therapeutic potential.

    Pyrrolizidine alkaloids (PAs) show a hazardous potential for humans and animals. They can possess mutagenic, teratogenic, cancerogenic and fetotoxic properties. One pathway of a human intoxication can be the use of medicinal plants which contain toxic PAs. The Traditional Indian medicine--in particular Ayurveda--is a popular and well-known healing system. Within this system several PA-containing plants are used which, on account of their PA level, represent a severe health risk. In general, it is not recommended to use plants containing those toxic compounds.

    Many food preservation strategies can be used for the control of microbial spoilage and oxidation; however, these quality problems are not yet controlled adequately. Although synthetic antimicrobial and antioxidant agents are approved in many countries, the use of natural safe and effective preservatives is a demand of food consumers and producers. This paper proposes medicinal plants, traditionally used to treat health disorders and prevent diseases, as a source of bioactive compounds having food additive properties. Medicinal plants are rich in terpenes and phenolic compounds that present antimicrobial and antioxidant properties; in addition, the literature revealed that these bioactive compounds extracted from other plants have been effective in food systems. In this context, the present hypothesis paper states that bioactive molecules extracted from medicinal plants can be used as antimicrobial and antioxidant additives in the food industry.

    Trace elemental analysis was carried out in various parts of some anti-diabetic medicinal plants using PIXE technique. A 3 MeV proton beam was used to excite the samples. The elements Cl, K, Ca, Ti, Cr, Mn, Fe, Ni, Cu, Zn, Br, Rb and Sr were identified and their concentrations were estimated. The results of the present study provide justification for the usage of these medicinal plants in the treatment of diabetes mellitus (DM) since they are found to contain appreciable amounts of the elements K, Ca, Cr, Mn, Cu, and Zn, which are responsible for potentiating insulin action. Our results show that the analyzed medicinal plants can be considered as potential sources for providing a reasonable amount of the required elements other than diet to the patients of DM. Moreover, these results can be used to set new standards for prescribing the dosage of the herbal drugs prepared from these plant materials.

    Full Text Available The use of medicinal plants plays a major role in the primary health care of animals in South Africa. A survey was conducted to document medicinal plants used to control parasites in goats in Kwezi and Ntambethemba villages in the Eastern Cape Province, South Africa. Information from 50 farmers and 3 herbalists was obtained through the use of a structured questionnaire, and a snowball sampling technique was used to identify key informants. The obtained data were analysed using PROC FREQ of SAS (2003, and fidelity level values were determined to estimate the healing potential of the mentioned plants. The survey revealed nine plant species belonging to eight families that were used to control parasites in goats. Asphodelaceae (22.22% was the most frequently used plant family. Leaves were the most used plant parts, constituting 60.38%. They were prepared either as infusions or decoctions of single plants or in mixtures. Aloe ferox, Acokanthera oppositifolia and Elephantorrhiza elephantina were the plants having the highest fidelity level for their use to control parasites, each scoring 100%, followed by Albuca setosa (83.33%. The study revealed low knowledge about ethnoveterinary medicine in the study area. It also revealed that information on ethno-veterinary medicine in this area is mostly confined to older people and there is danger that this knowledge can be lost before being passed on to other generations. Therefore, there is an urgent need to document information on these plant species so that the future generation can benefit. Further investigation should be carried out to validate the efficacy and safety of the above-mentioned plants so as to provide cheap alternative ways of controlling parasites.Keywords: ailments; ethno-veterinary practices; small ruminant; traditional medicine

    A biosensor for measuring the antidiabetic potential of medicinal plants was developed by covalent immobilization of α-glucosidase (AG) enzyme onto amine-functionalized multi-walled carbon nanotubes (MWCNTs-NH2). The immobilized enzyme was entrapped in freeze-thawed polyvinyl alcohol (PVA) together with p-nitrophenyl-α- d-glucopyranoside (PNPG) on the screen-printed carbon electrode at low pH to prevent the premature reaction between PNPG and AG enzyme. The enzymatic reaction within the biosensor is inhibited by bioactive compounds in the medicinal plant extracts. The capability of medicinal plants to inhibit the AG enzyme on the electrode correlates to the potential of the medicinal plants to inhibit the production of glucose from the carbohydrate in the human body. Thus, the inhibition indicates the antidiabetic potential of the medicinal plants. The performance of the biosensor was evaluated to measure the antidiabetic potential of three medicinal plants such as Tebengau ( Ehretis laevis), Cemumar ( Micromelum pubescens), and Kedondong ( Spondias dulcis) and acarbose (commercial antidiabetic drug) via cyclic voltammetry, amperometry, and spectrophotometry. The cyclic voltammetry (CV) response for the inhibition of the AG enzyme activity by Tebengau plant extracts showed a linear relation in the range from 0.423-8.29 μA, and the inhibition detection limit was 0.253 μA. The biosensor exhibited good sensitivity (0.422 μA/mg Tebengau plant extracts) and rapid response (22 s). The biosensor retains approximately 82.16 % of its initial activity even after 30 days of storage at 4 °C.

    Plants have been used throughout human history for food and medicine. However, many plants are toxic, and cannot easily be morphologically distinguished from non-toxic plants. DNA identification solves this problem and is widely used. Nonetheless, plant DNA barcode identification faces a number of challenges, and many studies have been conducted to find suitable barcodes. The present study was conducted to test the efficiency of commonly used primers, namely ITS2, rpoC1, and trnH-psbA, in order to find the best DNA barcode markers for the identification of medicinal plants in Malaysia. Fresh leaves from 12 medicinal plants that are commonly used by Malay traditional healers were collected from the Tropical Spice Garden, Pulau Pinang, and subjected to polymerase chain reaction amplification using ITS2, rpoC1, and trnH-psbA DNA markers. We found that trnH-psbA is the best DNA marker for the species-level identification of medicinal plants in Malaysia.

    Herbal medicines and traditionally used medicinal plants present an untapped potential for novel molecular target discovery using systems science and OMICS biotechnology driven strategies. Since up to 40% of the world's poor people have no access to government health services, traditional and folk medicines are often the only therapeutics available to them. In this vein, North East (NE) India is recognized for its rich bioresources. As part of the Indo-Burma hotspot, it is regarded as an epicenter of biodiversity for several plants having myriad traditional uses, including medicinal use. However, the improvement of these valuable bioresources through molecular breeding strategies, for example, using genic microsatellites or Simple Sequence Repeats (SSRs) or Expressed Sequence Tags (ESTs)-derived SSRs has not been fully utilized in large scale to date. In this study, we identified a total of 47,700 microsatellites from 109,609 ESTs of 11 medicinal plants (pineapple, papaya, noyontara, bitter orange, bermuda brass, ratalu, barbados nut, mango, mulberry, lotus, and guduchi) having proven antidiabetic properties. A total of 58,159 primer pairs were designed for the non-redundant 8060 SSR-positive ESTs and putative functions were assigned to 4483 unique contigs. Among the identified microsatellites, excluding mononucleotide repeats, di-/trinucleotides are predominant, among which repeat motifs of AG/CT and AAG/CTT were most abundant. Similarity search of SSR containing ESTs and antidiabetic gene sequences revealed 11 microsatellites linked to antidiabetic genes in five plants. GO term enrichment analysis revealed a total of 80 enriched GO terms widely distributed in 53 biological processes, 17 molecular functions, and 10 cellular components associated with the 11 markers. The present study therefore provides concrete insights into the frequency and distribution of SSRs in important medicinal resources. The microsatellite markers reported here markedly add to the genetic

    To estimate the heavy metal content in soil and selected medicinal plants procured from environmentally different sites of the same city. Methods Soil and plant samples of Abutilon indicum, Calotropis procera, Euphorbia hirta, Peristrophe bycaliculata, and Tinospora cordifolia were collected from 3 environmentally different sites of the city: heavy traffic area (HTA), industrial area (IA), and residential area (RA). Pb, Cd, Cr, and Ni were estimated in soil and plant samples by inductively coupled plasma emission spectrometry and compared. Results The level of heavy metal was higher in soil than in plant parts studied. Accumulation of heavy metals varied from plant to plant. Pb was the highest in Calotropis procera root from HTA site and the lowest in Peristrophe bycaliculata whole plant from IA site. It was also lower in residential area than in heavy traffic area. Conclusion The level of heavy metal content differed in the same medicinal plant collected from environmentally different sites of the same city. Thus, it reiterates our belief that every medicinal plant sample should be tested for contaminant load before processing it further for medication.

    Full Text Available The Kashmir valley represents temperate climatic conditions and is known for its bivoltine sericulture. The sericulture in the region however, sustains on tree type of plants. Majority of sericulturists in this traditional area have taken up mulberry cultivation on small land holdings as a life sustaining occupation. Other farmers with more land have taken up it as subsidiary occupation. Mulberry is facing stiff competition from other economic crops. In order to make the mulberry cultivation more profitable and sustainable, intercrops can be practiced with them. Medicinal plants like Lavendula officinalis, Atropa belladonna and Echinacea purpurea are important source of alkaloids and essential oils, which have huge demand in pharmaceutical industry. The wider spacing available in the tree type of plantation of mulberry facilitates the cultivation of these medicinal plants as an intercrop. The present paper focuses on utilization of medicinal plants as an intercrop with mulberry to generate an additional income to the progressive farmers as the biochemical studies shows that there is no significant impact on mulberry leaf quality and soil health.

    Full Text Available Forests are the main biological resource areas from where reportedly 80% of the medicinal plants are collected by the rural communities of the state. Traditional folk medicines, mainly based on plants, occupy a significant position today, especially in the developing countries, where modern health care service is limited. Medicinal plants are gaining global importance owing to the fact that herbal drugs are cost-effective, easily available and most reportedly, with negligible side effects. Safe, effective and inexpensive indigenous remedies had been practiced by the people of both tribal and rural society of Assam from time immemorial. Therefore, the need of the hour is to harness this natural resource sustainably for the socio-economic development of the indigenous communities. Hence, a strategy for sustainable harvesting practice needs to be developed that would ensure preservation of the valuable medicinal plants in situ while addressing the needs of the rural communities. The present study is, thus, an attempt to highlight the common medicinal plants of forested region as used by the rural poor community for different kinds of treatment as the rural local healers usually practice for treatment of diseases in their locality.

    This study was developed to evaluate the fungal burden, toxigenic molds, and mycotoxin contamination and to verify the effects of gamma radiation in four kinds of medicinal plants stored before and after 30 days of irradiation treatment. Eighty samples of medicinal plants (Peumus boldus, Camellia sinensis, Maytenus ilicifolia, and Cassia angustifolia) purchased from drugstores, wholesale, and open-air markets in São Paulo city, Brazil, were analyzed. The samples were treated using a (60)Co gamma ray source (Gammacell) with doses of 5 and 10 kGy. Nonirradiated samples were used as controls of fungal isolates. For enumeration of fungi on medicinal plants, serial dilutions of the samples were plated in duplicate onto dichloran 18% glycerol agar. The control samples revealed a high burden of molds, including toxigenic fungi. The process of gamma radiation was effective in reducing the number of CFU per gram in all irradiated samples of medicinal plants after 30 days of storage, using a dose of 10 kGy and maintaining samples in a protective package. No aflatoxins were detected. Gamma radiation treatment can be used as an effective method for preventing fungal deterioration of medicinal plants subject to long-term storage.

    Many scientific methods of analysis have been developed for the investigation of the constituents and biological activities of medicinal plants during the 50 years since the inaugural meeting of the Gesellschaft für Arzneipflanzenforschung (GA). The chromatographic (e. g., TLC, GLC, HPLC), spectroscopic (e. g., UV, IR, 1H- and 13C-NMR, MS), and biological (e. g., anticancer, anti-inflammatory, immunostimulant, antiprotozoal, CNS) techniques utilized for medicinal plant research are briefly reviewed. The contribution that advances in scientific methodology have made to our understanding of the actions of some herbal medicines (e. g., Echinacea, Ginkgo, St John's wort, Cannabis), as well as to ethnopharmacology and biotechnology, are briefly summarized. Plants have provided many medicinal drugs in the past and remain as a potential source of novel therapeutic agents. Despite all of the powerful analytical techniques available, the majority of plant species has not been investigated chemically or biologically in any great detail and even well known medicinal plants require further clinical study.

    2014-07-01

    In recent years the study of medicinal plants has become the focus of ever more extensive research all over the world due to their diversity and potential as source of medicinal products. According to the World Health Organization approximately 80% of world population makes use of medicinal herbs due to their believed therapeutic action. Besides being used as medicine, medicinal plants are also largely used as dietary supplements. The presence of radionuclides in plants constitutes one of the main pathways for their transfer to man. The amount of radioactive nuclides from U and Th series in edible vegetables are relatively well known since they have been the main concern of research conducted worldwide. Medicinal plants, on the other hand, have been neglected in these studies, possibly because the ingestion of radioactive material through their consumption has not been recognized or was considered insignificant. The objective of the present study was to determine the content of natural radionuclides from {sup 238}U and {sup 232}Th series in 25 species of medicinal plants used in Brazil, both as medicine and as dietary supplement. The medicinal plant samples were obtained in specialized pharmacies and drugstores. The raw plant and their extracts, produced as recommended by the National Agency for Sanitary Vigilance, were analyzed by Instrumental Neutron Activation Analyses for the determination of U and Th and by Total Alpha and Beta Counting after Radiochemical Separation for determination of {sup 226}Ra, {sup 228}Ra and {sup 210}Pb. In the raw plants the activity concentrations varied from 0,08 Bq kg{sup -1} to 8,0 Bq kg{sup -1} for thorium, from < LID to 22 Bq kg{sup -1} for uranium, from 1,8 Bq kg{sup -1} to 12 Bq kg{sup -1} for {sup 226}Ra, from 33 Bq kg{sup -1} to 74 Bq kg{sup -1} for {sup 228}Ra and from 10 Bq kg{sup -1} to 120 Bq kg{sup -1} for {sup 210}Pb. In the extracts, the activity concentrations varied from 9 mBq kg{sup -1} to 137 mBq kg{sup -1} for Th

    2012-08-01

    The bioactive compounds of medicinal plants are products of the plant itself or of endophytes living inside the plant. Endophytes isolated from eight different anticancer plants collected in Yunnan, China, were characterized by diverse 16S and 18S rRNA gene phylogenies. A functional gene-based molecular screening strategy was used to target nonribosomal peptide synthetase (NRPS) and type I polyketide synthase (PKS) genes in endophytes. Bioinformatic analysis of these biosynthetic pathways facilitated inference of the potential bioactivity of endophyte natural products, suggesting that the isolated endophytes are capable of producing a plethora of secondary metabolites. All of the endophyte culture broth extracts demonstrated antiproliferative effects in at least one test assay, either cytotoxic, antibacterial or antifungal. From the perspective of natural product discovery, this study confirms the potential for endophytes from medicinal plants to produce anticancer, antibacterial and antifungal compounds. In addition, PKS and NRPS gene screening is a valuable method for screening isolates of biosynthetic potential.

    Full Text Available Given the importance of studying the knowledge, beliefs, and practices of migrant communities to understand the dynamics of plant resource use, we reviewed the scientific literature concerning the use of medicinal plants by migrant populations engaged in international or long-distance migrations. We considered the importance of two processes: (1 adaptation to the new flora of the host country (i.e., substitution and incorporation of plants in the pharmacopoeia and (2 continued use and acquisition of the original flora from migrants' home countries (i.e., importation, cultivation, and/or continued use of plants that grow in both host and home environments. We suggest that, depending on the specific context and conditions of migration, different processes that determine the use and/or selection of plants as herbal medicines may become predominant.

    Full Text Available Medicinal and wild food plants have always played an important role in people’s lives especially in rural areas. Similar situation can be said for islands due to the reason of them being isolated from mainland. This paper reports an ethnobotanical investigations performed in 2009 and 2014 to determine medicinal and wild food plants of Marmara Island. A total of 30 individuals were interviewed (19 men, 11 women. Totally, 22 plants are recorded as used as traditional folk medicine for the region, and nine of these are also used as a source of wild food. Furthermore, 18 taxa are wild sources of nutrition for the area. The plants most commonly used in the region as medicinal remedies were Salvia fruticosa, Hypericum perforatum, Ficus carica, and Mentha spicata. Plants are mostly used for the treatment of abdominal pain, the common cold, and haemorrhoids. The species most commonly used for food are: Salvia fruticosa, Arbutus unedo, Rhus coriaria, and Rubus sanctus. This ethnobotanical study conducted in this island will enable the traditional use of wild plants both as food sources and herbal remedies to be passed on to future generations.

  15. Effects of rare earth elements on growth and metabolism of medicinal plants

    2013-02-01

    Full Text Available The rare earth elements (REEs are a set of 17 chemical elements. They include the lanthanide series from lanthanum (La to lutetium (Lu, scandium (Sc, and yttrium (Y in the periodic table. Although REEs are used widely in industry and agriculture in China for a long time, there has been increasing interest in application of REEs to medicinal plants in recent years. In this paper, we summarize researches in the past few decades regarding the effects of REEs on the germination of seeds, the growth of roots, total biomass, and the production of its secondary metabolites, as well as their effects on the absorption of minerals and metals by medicinal plants. By compilation and analysis of these data, we found that REEs have promoting effects at low concentrations and negative effects at comparatively high concentrations. However, most studies focused only on a few REEs, i.e., La, cerium (Ce, neodymium (Nd and europium (Eu, and they made main emphasis on their effects on regulation of secondary metabolism in tissue-cultured plants, rather than cultivated medicinal plants. Advanced research should be invested regarding on the effects of REEs on yields of cultivated plants, specifically medicinal plants.

    Context: Acne vulgaris affects about 85% of teenagers and may continue to adulthood. There are about two million visits to physicians per year for teenagers and the direct cost of acne treatment in the US exceeds $1 billion per year. Evidence Acquisition: A wide variety of treatment regimens exist for acne vulgaris including benzoil peroxide, retinoids, isotretinoids, keratolytic soaps, alpha hydroxy acids, azelaic acid, salicilic acid as well as hormonal, anti-androgen or antiseborrheic treatments. However, none of these methods is free of side effects and their exact role in therapy is not clear. In this paper apart from presenting the possible causes of acne vulgaris and its available drugs, recently published papers about medicinal plants used in the treatment of acne vulgaris were reviewed. Results: Consumption of alternative and complementary medicine, including medicinal plants, is increasing and is common amongst patients affected by acne and infectious skin diseases. Medicinal plants have a long history of use and have been shown to possess low side effects. These plants are a reliable source for preparation of new drugs. Conclusions: Many plants seem to have inhibitory effects on the growth of bacteria, fungi and viruses in vitro. However, there are a few clinical evidences about the effectiveness and safety of these plants in the treatment of acne and other skin infections. PMID:26862380

    To document ethnobotanical informations of useful woody plant species in the region of Kotli, Azad Kashmir. Methods: An ethnobotanical survey was conducted in Kotli. Data were collected by interview and semi structured questionnaire from selected local informants and traditional practitioners as well as by field assessment. Results: The present study documented the etnobotanical uses of 33 woody plant species. Most of the species have been used for dual purpose. Only 5 species are used for one purpose. Study revealed all species have medicinal value, among which 21 were used as fuel wood species, 16 as fodder species, 4 as timber wood species, 12 as edible fruit species, 6 as fence or hedge plant, 7 as ornamental species and 12 species had other uses. Conclusions: Medicinal plants are still widely used for health care by locals of Kotli. Some species of woodlands seem to be vulnerable to overcollection and deforestation. As the young generation is diverted toward allelopathic medicines, ethnobotanical knowledges of important medicinal plants are restricted to the old people only. It is suggested to close the forest of district Kotli for next two to three decades for the conservation of plant biodiversity.

    Diarrhea is a serious problem affecting 3-5 billion people per year around the world, especially children of below 5 years. 70% of the world population uses traditional and indigenous medicine for their primary health care. The facts of these indigenous remedies are passed verbally and sometimes as documents. Since ancient time, Ayurveda is the main system of healing in South East Asian countries. Indian literature from ayurvedic texts and other books claim the potency of several plants in the treatment of diarrhea. As the global prospective of ayurvedic medicine is increasing, interest regarding the scientific basis of their action is parallely increasing. Researchers are doing experiments to establish the relation between the claimed action and observed pharmacological activities. In the present article, an attempt was made to compile the scientific basis of medicinal plants used to cure diarrhea in Ayurveda. Literature was collected via electronic search (PubMed, ScienceDirect, Medline, and Google Scholar) from published articles that reports antidiarrheal activity of plants that were mentioned in Ayurveda classics. A total of 109 plant species belonging to 58 families were reported for their antidiarrheal activity. Several Indian medicinal plants have demonstrated promising antidiarrheal effects, but the studies on the antidiarrheal potentials of these plants are not taken beyond proof of concept stage. It is hoped that the article would stimulate future clinical studies because of the paucity of knowledge in this area.

    Objective. The aim of this systematic review was to investigate the advances in the study of medicinal plants and their biologic effects on periodontitis in animal models. Study Design. A systematic search was conducted by three independent researchers, who screened articles published up to March/2016, to identify the studies that contained sufficient and clear information on the association of the medicinal plants and periodontitis in murine models. The searches were performed using PubMed, Cochrane, and Science Direct databases. Results. After a critical analysis of titles and abstracts, 30 studies were finally eligible for analysis. The studies presented a great diversity of the experiment designed regarding the methods of induced periodontitis and the evaluation of the medicinal plants efficacy. None of the studies described the possible toxic effects associated with the administration of the plant material to animals and whether they could prevent damage to organs caused by systemic effect of induced periodontitis. Gel-based formulations containing plant substances are seen as an interesting strategy to treat periodontitis. Conclusions. In this systematic review, the state-of-the-art knowledge on the medicinal plants and the induced periodontitis was critically evaluated and discussed from the experiment designed to the possible clinical application.

    Full Text Available Plants growing in the Judea region are widely used in traditional medicine of the Levant region. Nevertheless, they have not so far been sufficiently analyzed and their medicinal potential has not been evaluated. This study is the first attempt to fill the gap in the knowledge of the plants growing in the region. Comprehensive data mining of online botanical databases and peer-reviewed scientific literature including ethno-pharmacological surveys from the Levant region was applied to compile a full list of plants growing in the Judea region, with the focus on their medicinal applications. Around 1300 plants growing in the Judea region were identified. Of them, 25% have medicinal applications which were analyzed in this study. Screening for chemical-protein interactions, together with the network-based analysis of potential targets, will facilitate discovery and therapeutic applications of the Judea region plants. Such an approach could also be applied as an integrative platform for further searching the potential therapeutic targets of plants growing in other regions of the world.

    Ethnobotanical relevance Medicinal and food plants in the Basque Country are an integral part of a fast changing culture. With a distinct tradition and language, this region of Europe provides an important example demonstrating the changing role of local and traditional knowledge in industrial countries. As other Mediterranean regions it preserves a rich heritage of using plants as medicine and food, offering a unique opportunity for studying the medicine food interface in an ethnopharmacological context. Therefore, the key goal of this study has been to contribute to an understanding of local and traditional plant usage, to evaluate their uses as food and medicine as well as to critically assess the role of these plants in the south of the Basque Country contributing to an understanding of how foods and medicines are used. Methods A mixed methods approach, including participant observation; open and semi structured interviews was used. Ethnobotanical field work included 183 people, ages ranged from 24 to 98 years old with a majority being between 70 and 80 years old (mean age 71) from 31 towns of three different regions. The basic interview was a one-to-one meeting, which often included field walking and collection of samples as directed by the informants. 700 voucher specimens (most of them with duplicates) were collected for the data obtained. Using SPSS version 20 the gathered information was processed and the replies of the different informants were subsequently organised in variables like medicine and food plants, part of the plants used, forms of preparations, zones preferred for collecting these plants. The data were analysed based on the frequency of records. This type of approach allows us to understand the way the informant’s categorize the species, and how these categories are distributed along the sample. In order to analyse the data three main categories of use were distinguished: Medicine (M), Food (F) and an intermediate Health-Food (H-F). The

    Full Text Available Abstract Background This is a first description of the main ethnoveterinary features of the peasants in the Sierras de Córdoba. The aim of this study was to analyze the use of medicinal plants and other traditional therapeutic practices for healing domestic animals and cattle. Our particular goals were to: characterize veterinary ethnobotanical knowledge considering age, gender and role of the specialists; interpret the cultural features of the traditional local veterinary medicine and plant uses associated to it; compare the plants used in traditional veterinary medicine, with those used in human medicine in the same region. Methods Fieldwork was carried out as part of an ethnobotanic regional study where 64 informants were interviewed regarding medicinal plants used in veterinary medicine throughout 2001-2010. Based participant observation and open and semi-structured interviews we obtained information on the traditional practices of diagnosis and healing, focusing on the veterinary uses given to plants (part of the plant used, method of preparation and administration. Plants speciemens were collected with the informants and their vernacular and scientific names were registered in a database. Non-parametric statistic was used to evaluate differences in medicinal plant knowledge, use, and valorization by local people. A comparison between traditional veterinary medicine and previous human medicine studies developed in the region was performed by analyzing the percentages of common species and uses, and by considering Sorensen's Similarity Index. Results A total of 127 medicinal uses were registered, corresponding to 70 species of plants belonging to 39 botanic families. Veterinary ethnobotanical knowledge was specialized, restricted, in general, to cattle breeders (mainly men and to a less degree to healers, and was independent of the age of the interviewees. Native plants were mostly used as skin cicatrizants, disinfectants or for treating

    Full Text Available Aim: The aim was to document the ethnoveterinary medicinal plants, their preparation, and application methods used by traditional healers in treating different animal diseases, in four districts with different culture and languages in southern Ethiopia. Materials and Methods: Information of ethnoveterinary medicinal plants was obtained through in-depth direct interview with the local healers and field observations. A descriptive statistics was used to analyze the reported ethnoveterinary medicinal plants and associated indigenous knowledge. The informant consensus factor (ICF was calculated for each category of diseases to identify the agreements of the informants on the reported cures. Preference ranking was used to assess the degree of effectiveness of certain medicinal plants against most prevalent animal diseases in the area. Results: The healers had a very high intention to keep their traditional knowledge secrete and none of them was ready to transfer their knowledge either freely or on incentive bases to other people; they need to convey their knowledge only to their selected scions after getting very old. A total of 49 plant species used to treat 26 animal ailments were botanically classified and distributed into 34 families. The most commonly used plant parts for remedy preparations were leaves (38.8%, followed by whole roots (20.4%. Calpurnia aurea (Ait. Benth was the most preferred effective treatment against external parasite and skin problem, which is the most prevalent disease with the highest ICF (0.68. Conclusion: The study suggests that the community of the study districts depend largely on ethnoveterinary medicinal plants for the treatment of different animal ailments though the healers have a very high intention to keep their traditional knowledge secrete. Commonly reported plant species need to be tested for their antimicrobial activities in vitro and validated their active ingredients in order to recommend effective

    Wei Gu

    Full Text Available Selaginellaceae is a family of nonseed plants with special evolutionary significance. Plants of the family Selaginellaceae are similarly shaped and easily confused, complicating identification via traditional methods. This study explored, for the first time, the use of the DNA barcode ITS2 to identify medicinal plants of the Selaginellaceae family.In our study, 103 samples were collected from the main distribution areas in China; these samples represented 34 species and contained almost all of the medicinal plants of Selaginellaceae. The ITS2 region of the genome was amplified from these samples and sequenced using universal primers and reaction conditions. The success rates of the PCR amplification and sequencing were 100%. There was significant divergence between the interspecific and intraspecific genetic distances of the ITS2 regions, while the presence of a barcoding gap was obvious. Using the BLAST1 and nearest distance methods, our results proved that the ITS2 regions could successfully identify the species of all Selaginellaceae samples examined. In addition, the secondary structures of ITS2 in the helical regions displayed clear differences in stem loop number, size, position, and screw angle among the medicinal plants of Selaginellaceae. Furthermore, cluster analysis using the ITS2 barcode supported the relationship between the species of Selaginellaceae established by traditional morphological methods.The ITS2 barcode can effectively identify medicinal plants of Selaginellaceae. The results provide a scientific basis for the precise identification of plants of the family Selaginellaceae and the reasonable development of these resources. This study may broaden the application of DNA barcoding in the medicinal plant field and benefit phylogenetic investigations.

    Knowledge of medicinal plants is not only one of the main components in the structure of knowledge in local medical systems but also one of the most studied resources. This study uses a systematic review and meta-analysis of a compilation of ethnobiological studies with a medicinal plant component and the variable of gender to evaluate whether there is a gender-based pattern in medicinal plant knowledge on different scales (national, continental, and global). In this study, three types of meta-analysis are conducted on different scales. We detect no significant differences on the global level; women and men have the same rich knowledge. On the national and continental levels, significant differences are observed in both directions (significant for men and for women), and a lack of significant differences in the knowledge of the genders is also observed. This finding demonstrates that there is no gender-based pattern for knowledge on different scales. PMID:27795730

    Full Text Available Neurotransmitter modification is an important method for the treatment of memory loss or amnesia. Cholinomimetic drugs, particularly, acetylcholine esterase inhibitors are the mainstream in pharmacotherapy of amnesia. Donepezil, tacrine, galantamine, and rivastigmine are cholinesterase inhibitors which are widely used in the treatment of amnesia, however, their therapeutic effects are not significant. Therefore, other possibilities including herbal medicine sources have been considered for memory loss therapy. There are some Medicinal plants with cholinomimetic property which mostly possess antioxidant activity, too. These plants may not only ameliorate amnesia but also can be a good source for drug discovery. In this paper other than introducing the medicinal plants and their components affective on cholinergic system and effective on memory loss, their probable advantages over synthetic drugs are discussed.

    Full Text Available The fruits of four wild plants, namely, Capparis decidua, Ficus carica, Syzygium cumini, and Ziziphus jujuba, are separately used as traditional dietary and remedial agents in remote areas of Khyber Pakhtunkhwa, Pakistan. The results of our study on these four plants revealed that the examined fruits were a valuable source of nutraceuticals and exhibited good level of antimicrobial activity. The fruits of these four investigated plants are promising source of polyphenols, flavonoids, alkaloids, terpenoids, and saponins. These four plants' fruits are good sources of iron, zinc, copper, manganese, selenium, and chromium. It was also observed that these fruits are potential source of antioxidant agent and the possible reason could be that these samples had good amount of phytochemicals. Hence, the proper propagation, conservation, and chemical investigation are recommended so that these fruits should be incorporated for the eradication of food and health related problems.

    The use of medicinal plants plays a major role in the primary health care of animals in South Africa. A survey was conducted to document medicinal plants used to control parasites in goats in Kwezi and Ntambethemba villages in the Eastern Cape Province, South Africa. Information from 50 farmers and 3 herbalists was obtained through the use of a structured questionnaire, and a snowball sampling technique was used to identify key informants. The obtained data were analysed using PROC FREQ of SAS (2003), and fidelity level values were determined to estimate the healing potential of the mentioned plants. The survey revealed nine plant species belonging to eight families that were used to control parasites in goats. Asphodelaceae (22.22%) was the most frequently used plant family. Leaves were the most used plant parts, constituting 60.38%. They were prepared either as infusions or decoctions of single plants or in mixtures. Aloe ferox, Acokanthera oppositifolia and Elephantorrhiza elephantina were the plants having the highest fidelity level for their use to control parasites, each scoring 100%, followed by Albuca setosa (83.33%). The study revealed low knowledge about ethnoveterinary medicine in the study area. It also revealed that information on ethno-veterinary medicine in this area is mostly confined to older people and there is danger that this knowledge can be lost before being passed on to other generations. Therefore, there is an urgent need to document information on these plant species so that the future generation can benefit. Further investigation should be carried out to validate the efficacy and safety of the above-mentioned plants so as to provide cheap alternative ways of controlling parasites.

Currently, medicinal plants are traditional practices for an extensive range of therapeutics and pharmacological activities like hypoglycemic, immunological, antiviral, anti-inflammatory, anti-hepatic, cardiovascular and central nervous effect. In the past, the use of plant based medicines was mainly restricted to developing countries because of insufficient resources, but currently the trend is changed and natural products as a source of medicines are growing rapidly in developed countries. It is confirmed from research articles that nearly about 75%– 80% of the reserved zone inhabitants used natural products for their health remedies. In all, about 250 000–500 000 species of plants exist worldwide and almost 800 plants have been documented for use in folklore systems of medicine. Regarding to this, Malaysia is being accepted as one of the largest biodiversity countries. In Malaysia, 12 000 species of natural products exist and 1200 are documented to have remedial potential against various diseases. In the market, a variety of allopathic drugs are available, but are linked to various side effects. Hence, there is rising interest in the direction to plant based medicines remedies with a basic tactic towards the nature. The anti-diabetic drugs from natural products source in current use and their same way of producing action are preferred mainly due to affordable price, easy availability and minor harmful effect on human beings. Therefore, the aim of the present research work was to review various Malaysian medicinal plants having potential in attenuation of high level of blood glucose.

    Traditional knowledge is influenced by ancestry, inter-cultural diffusion and interaction with the natural environment. It is problematic to assess the contributions of these influences independently because closely related ethnic groups may also be geographically close, exposed to similar environments and able to exchange knowledge readily. Medicinal plant use is one of the most important components of traditional knowledge, since plants provide healthcare for up to 80% of the world's population. Here, we assess the significance of ancestry, geographical proximity of cultures and the environment in determining medicinal plant use for 12 ethnic groups in Nepal. Incorporating phylogenetic information to account for plant evolutionary relatedness, we calculate pairwise distances that describe differences in the ethnic groups' medicinal floras and floristic environments. We also determine linguistic relatedness and geographical separation for all pairs of ethnic groups. We show that medicinal uses are most similar when cultures are found in similar floristic environments. The correlation between medicinal flora and floristic environment was positive and strongly significant, in contrast to the effects of shared ancestry and geographical proximity. These findings demonstrate the importance of adaptation to local environments, even at small spatial scale, in shaping traditional knowledge during human cultural evolution.

    ABSTRACT Medicinal and aromatic plants are the foremost source of life economy drugs for the majority of the world’s population. Secondary plant metabolites are essential for life as drugs, fragrances, pigments and food additives. Botanical study of plants is an inevitable step in the ethno-pharmacological approach and it is the reference system since it allows sitting scientifically research that follows from of these new concepts. So, the purpose of many scientists is to advance a new approach useful for identifying plants within a folk pharmacopoeia which deserve the increased research attention of phytochemists and pharmacologists. In the objective to study medicinal plants, usually we start by extraction of the bioactive compounds, which is an essential stage. So, new important extraction processes were elaborated to recover bioactive constituants from herbal plants by augmenting the yield at inferior fee. Recent approachs and methods used in isolation and characterization of active compounds from herbal preparations are also given according to their important roles. Besides, in the present work, an update on some biological activities properties of medicinal plants is reviewed.

    Full Text Available Medicinal and aromatic plants are the foremost source of life economy drugs for the majority of the world’s population. Secondary plant metabolites are essential for life as drugs, fragrances, pigments and food additives. Botanical study of plants is an inevitable step in the ethnopharmacological approach and it is the reference system since it allows sitting scientifically research that follows from of these new concepts. So, the purpose of many scientists is to advance a new approach useful for identifying plants within a folk pharmacopoeia which deserve the increased research attention of phytochemists and pharmacologists. In the objective to study medicinal plants, usually we start by extraction of the bioactive compounds, which is an essential stage. So, new important extraction processes were elaborated to recover bioactive constituants from herbal plants by augmenting the yield at inferior fee. Recent approachs and methods used in isolation and characterization of active compounds from herbal preparations are also given according to their important roles. Besides, in the present work, an update on some biological activities properties of medicinal plants is reviewed.

    Full Text Available Ayurveda, Siddha, Unani and Folk (Tribal medicines are the major systems of indigenous medicines. Over three-quarters of the world population relies mainly on plants and plant extracts for health care. Unlike many diseases, which can be attributed to the life style of modern man, asthma is an ancient illness. Mast cells play an important role in some type of allergic reaction because the antibody that causes the allergic reaction that is Ig E have the mast cells which contains about a thousand tiny granules. These granules are loaded with dozens of potent chemicals or mediators, the most powerful in which are histamine and a newly discovered group called leukotrienes. From the present laboratory, there are number of medicinal plants have been reported for antihistaminic/anti-asthmatic activities. Some of them are Achyranthes aspera, Tephrosia purpurea,Dolichos lablab, Eclipta alba, Jasminum sambac, Balanites aegyptiaca, Viscum album, Tridex procumbens, Glycyrrhiza glabra and Cassia fistula. Recently, Soni (2009-2011 has reported 100% inhibition ofLeukotrienes (which cause asthma from the EtoAC fraction of Bacopa monnieri extract. It is suggested that formulation and patent of the reported medicinal plants is mandatory for further use against asthma and if possible, clinical trials should be done of these plants for their appropriate use.

    Full Text Available Assam is endowed with a rich wealth of medicinal plants. It has the richest reservoir of plant diversity of India and is one of the hot diversity spots of the world supporting about 50% of India’s biodiversity. Traditional medical practice has been recognized by the World health Organization (WHO as a building block of primary healthcare. Assam has a rich traditional knowledge of folk medicinal practices. But rapid fragmentation of natural habitats and unrestricted exploitation coupled with limited cultivation and insufficient attempts for its replacement has decreased this knowledge day by day. As a result, this wild stock of the medicinal plant species has been markedly depleted with increasing the risk of loosing their genetic diversity and the medicinal quality of these plants remains unknown.Many species are extinct or on the verge of extinction before they are known for their scientific uses. In order to categorize and update the list of threatened species, the International Union for Conservation of Nature and Natural Resources (IUCN has recognized the categories on the basis of geographical range, populations and fragmentation of populations.The present study was carried out in Sonitpur district of Assam for the documentation of ethnomedicinal importance of such threatened plants species.

    The purpose of this investigation was to determine the antioxidant potentials and anti-glucosidase activities of six tropical medicinal plants. The levels of phenolic constituents in these medicinal plants were also quantified and compared. Antioxidation potentials were determined colorimetrically for scavenging activities against DPPH and NO radicals. Metal chelating assay was based on the measurement of iron-ferrozine absorbance at 562 nm. Anti-diabetic potentials were measured by using α-glucosidase as target enzyme. Medicinal plants' total phenolic, total flavonoid and hydroxycinnamic acid contents were determined using spectrophotometric methods, by comparison to standard plots prepared using gallic acid, quercetin and caffeic acid standards, respectively. Radical scavenging and metal chelating activities were detected in all medicinal plants, in concentration-dependent manners. Among the six plants tested, C. nutans, C. formosana and H. diffusa were found to possess α-glucosidase inhibitory activities. Spectrophotometric analysis indicated that the total phenolic, total flavonoid and hydroxycinnamic acid contents ranged from 12.13-21.39 mg GAE per g of dry sample, 1.83-9.86 mg QE per g of dry sample, and 0.91-2.74 mg CAE per g of dry sample, respectively. Our results suggested that C. nutans and C. formosana could potentially be used for the isolation of potent antioxidants and anti-diabetic compounds. To the best of our knowledge, this study represents the first time that C. nutans (Acanthaceae family) was reported in literature with glucosidase inhibition activity.

    Cold is a kind of mild and self-limiting viral illness that is considered as a prevalent disease with global occurrence and is caused by more than 200 types of viruses. Ethnobotanical studies and the use traditional experiences have increased the probability of detecting effective medicinal substances for cold by 40%. This study aimed to identify effective medicinal plants for cold in Lorestan province. Traditional medical information of this work was obtained from information from indigenous people in 8 cities of Lorestan province. A previously prepared questionnaire was given to trained health liaisons to record the people's beliefs about the plants. The results showed that 23 medicinal plants were used in Lorestan province for treating cold and its symptoms (cough, sore throat, sneezing, runny nose, etc). Plants studied in this article contained bioactive substances that are recommended as the most popular traditional treatments. More research studies should be done on the efficacy and the potential harms of medicinal plants used by people, and in the case of their positive pharmacological impacts, they can be used to produce natural and effective drugs for cold.

    The endophytic actinomycetes constitute one of the fascinating group of microorganisms associated with a wide range of plant species. The diversity of actinomycetes in plants and their tissue parts is a matter of debate as no consensus are derived between individual studies. Nevertheless, their diversity correlates with the occurrence in plant species harboured in unique regions of biologically diverse areas called "hot spots." Recent advances in the isolation techniques have facilitated the isolation of rare taxa from these environments. The biosynthetic ability of the endophytic actinomycetes has proven beyond doubt that these organisms have the potential to synthesize an array of compounds with novelty in structure and bioactivity and as a result are preferred in the natural product screening programs. In the years to come, the scientific world may await to discover many more novel actinomycete taxa with metabolic diversity and applications in therapeutics.

    Plants have played significant roles as medicine during pregnancy, birth, and postpartum care in many rural areas of the world. In addition to this, plants have been used for centuries to treat infertility and related reproduction problems. The aim of this paper was to review the current status of plant species used in maternal healthcare, including infertility, in South Africa, in terms of scientific evaluation for efficacy and safety. In addition to this, the role of medicinal plants as a tool in achieving the MDG5 of reducing maternal mortality by 2015 was evaluated. A search was done with the aid of Google Scholar, PubMed, Science Direct, peer-reviewed papers, and books, using keywords such as child birth, labour pain, maternal health, maternal mortality, menstrual pains, and postpartum. The plants listed in the different research articles were classified according to their use and the target effect of a plant extract or compound on reproductive function. Eighty-four plant species were found to be used to treat infertility and related problems. Twenty plant species are used during pregnancy, while 26 plant species are used to ease childbirth. For postpartum healing and any problems after childbirth, nine plant species were recorded. Unhealthy pregnancy and birth complications are among the factors that contribute to the loss of cognitive potential in the developing world's children, condemning them to impoverished lives. The best way to keep a country poor is to rob its children of their full developmental potential. In this respect, medicinal plants play a significant role in reducing maternal mortality and ensuring the birth of healthy children.

The characteristic high blood sugar levels result from either lack of the hormone insulin (type 1 diabetes, T1D, or because body tissues do not respond to the hormone (type 2 diabetes, T2D. T1D patients currently need exogenous insulin for life, while for T2D patients who do not respond to diet and exercise regimes, oral anti-diabetic drugs (OADs and sometimes insulin are administered to help keep their blood glucose as normal as possible. As neither the administration of insulin nor OADs is curative, many patients develop tissue degenerative processes that result in life-threatening diabetes comorbidities. Several surveys of medicinal plants used as anti-diabetic agents amongst different peoples have been published. Some of this interest is driven by the ongoing diabetes pandemic coupled with the inadequacies associated with the current state of-the-art care and management of the syndrome. However, there is a huge cleft between traditional medicine and modern (Western medicine, with the latter understandably demanding meaningful and scientific validation of anecdotal evidence for acceptance of the former. The main problems for clinical evaluation of medicinal plants with promising anti-diabetic properties reside both with the complexity of components of the plant materials and with the lack of full understanding of the diabetes disease etiology. This review is therefore focused on why research activities involving an integration of Systems Biology-based technologies of pharmacogenomics, metabolomics, and bioinformatics with standard clinical data

    Proton induced X-ray emission (PIXE) and proton induced {gamma}-ray emission (PIGE) techniques are employed for the determination of essential and trace elements in some commonly used medicinal plants of north east India. Light elements such as Na, Mg, Al and P are determined by PIGE while medium Z elements such as K, Ca, Mn, Fe, Cu, Zn, Rb and Sr are determined by PIXE. Analysis is performed on pellets (thick targets) prepared using powders of the specimens which, in turn, are obtained following a series of processing steps. Plant based biological certified reference materials (CRMs) served as standards for quantification. These elements are found to be present in varying concentrations in the studied plants, with the contents of Mn and Zn being notably large in certain specimens. Medicinal properties possessed by these plants have been correlated with their elemental distribution.

    2011-01-01

    Great apes sometimes feed on items of low nutritional value with bioactive secondary compounds. These molecules may be toxic and neophobia is presumed to be an essential factor in avoiding the ingestion of noxious items. The aim of this study is to investigate, in captive orangutans, individual and social learning involved in the discovery and ingestion of new items. We presented novel aromatic plants - 11 fresh plants and 4 infused plants - to 4 captive weaned Bornean orangutans, both under isolated and group conditions, and recorded their behaviour and interactions between group members. All animals tasted by nibbling or ingested most of the plants presented. Regardless of the experimental condition, individual responses did not vary visibly across the sessions, despite numerous close observations, and food transfers between individuals were observed. Our results suggest that a low level of neophobia and a strong propensity to look to conspecifics for information allow Bornean orangutans to expand their diet after weaning. Our results also provide some evidence that olfaction is a key sense in determining food edibility based on previous experience.

Sabah, being part of Borneo, is rich in plant biodiversity. There is also an abundance of medicinal plants and other plants for everyday use. There is a great awarness regarding association between low density lipoprotein reduction and decreased cardiovascular disease mortality. The antihyperlipidaemic activity of herbs plays an important role in the reduction of cardiovascular diseases, which is the top disease that causes mortality all over the world. Lipid-lowering activity of medicinal plant for phytomedicine research and drug development for such a disease are now focused all over the world. A plant-based diet rich in fruit, vegetables, and legumes and low in saturated fat is an effective prescription for anyone with more severe atherosclerosis. Howerver, there are few herbs available that provide some protection for persons with the above disease. The antihyperlipidaemia property in plant plays a vital role to reduce atherosclerosis. Thus, there is an increasing search for the lipid lowering agents from natural origin. In this review an attempt has been made to give an overview of the antihyperlipidemic activity in traditional medicinal plants found widely in Kadazan and Dusun communities in Sabah, Malaysia. The antihyperlipidemic activity of the traditional medicinal plants in these communities is more helpful for the development of new drugs used in the protection against dyslipidemia or atherosclerosis.

    Full Text Available The side effects and the emerging resistance to the available drugs against leishmaniasis and trypanosomiasis led to the urgent need for new therapeutic agents against these diseases. Thirty one extracts of thirteen medicinal plants from the Brazilian Cerrado were therefore evaluated in vitro for their antiprotozoal activity against promastigotes of Leishmania donovani, and amastigotes of Trypanosoma cruzi. Among the selected plants, Casearia sylvestris var. lingua was the most active against both L. donovani and T. cruzi. Fifteen extracts were active against promastigotes of L. donovani with concentrations inhibiting 50% of parasite growth (IC50 between 0.1-10 µg/ml, particularly those of Annona crassiflora (Annonaceae, Himatanthus obovatus (Apocynaceae, Guarea kunthiana (Meliaceae, Cupania vernalis (Sapindaceae, and Serjania lethalis (Sapindaceae. With regard to amastigotes of T. cruzi, extracts of A. crassiflora, Duguetia furfuracea (Annonaceae, and C. sylvestris var. lingua were active with IC50 values between 0.3-10 µg/ml. Bioassay fractionations of the more active extracts are under progress to identify the active antiparasite compounds.

    The medicinal plant Ferula has been widely used in Asian medicine, especially in Uyghur medicine in Xinjiang, China. Given that various substitutes and closely related species have similar morphological characteristics, Ferula is difficult to distinguish based on morphology alone, thereby causing confusion and threatening the safe use of Ferula. In this study, internal transcribed spacer 2 (ITS2) sequences were analyzed and assessed for the accurate identification of two salable Ferula species (Ferula sinkiangensis and Ferula fukangensis) and eight substitutes or closely related species. Results showed that the sequence length of ITS2 ranged from 451 bp to 45 bp, whereas guanine and cytosine contents (GC) were from 53.6% to 56.2%. A total of 77 variation sites were detected, including 63 base mutations and 14 insertion/deletion mutations. The ITS2 sequence correctly identified 100% of the samples at the species level using the basic local alignment search tool 1 and nearest-distance method. Furthermore, neighbor-joining tree successfully identified the genuine plants F. sinkiangensis and F. fukangensis from their succedaneum and closely related species. These results indicated that ITS2 sequence could be used as a valuable barcode to distinguish Uyghur medicine Ferula from counterfeits and closely related species. This study may broaden DNA barcoding application in the Uyghur medicinal plant field.

    Full Text Available Abstract An ethnobotanical study was conducted from October 2005 to June 2006 to investigate the uses of medicinal plants by people in Zegie Peninsula, northwestern Ethiopia. Information was gathered from 200 people: 70 female and 130 males, using semistructured questionnaire. Of which, six were male local healers. The informants, except the healers, were selected randomly and no appointment was made prior to the visits. Informant consensus factor (ICF for category of aliments and the fidelity level (FL of the medicinal plants were determined. Sixty-seven medicinal plants used as a cure for 52 aliments were documented. They are distributed across 42 families and 64 genera. The most frequently utilized plant part was the underground part (root/rhizome/bulb (42%. The largest number of remedies was used to treat gastrointestinal disorder and parasites infections (22.8% followed by external injuries and parasites infections (22.1%. The administration routes are oral (51.4%, external (38.6%, nasal (7.9%, and ear (2.1%. The medicinal plants that were presumed to be effective in treating a certain category of disease, such as 'mich' and febrile diseases (0.80 had higher ICF values. This probably indicates a high incidence of these types of diseases in the region, possibly due to the poor socio-economic and sanitary conditions of this people. The medicinal plants that are widely used by the local people or used as a remedy for a specific aliment have higher FL values (Carissa spinarum, Clausena anisata, Acokanthera schimperi, Calpurnia aurea, Ficus thonningii, and Cyphostemma junceum than those that are less popular or used to treat more than one type of aliments (Plumbago zeylanicum, Dorstenia barnimiana.

    Free listing is a methodological tool that is widely used in various scientific disciplines. A typical assumption of this approach is that individual lists reflect a subset of total knowledge and that the first items listed are the most culturally important. However, little is known about how cognitive processes influence free lists. In this study, we assess how recent memory of use, autonoetic and anoetic memory, and long-term associative memory can affect the composition and order of items in free lists and evaluate whether free lists indicate the most important items. Based on a model of local knowledge about medicinal plants and their therapeutic targets, which was collected via individual semi-structured interviews, we classify each item recorded in free lists according to the last time that the item was used by the informant (recently or long ago), the type of relevant memory (autonoetic or anoetic memory) and the existing associations between therapeutic targets (similar or random). We find that individuals have a tendency to recall information about medicinal plants used during the preceding year and that the recalled plants were also the most important plants during this period. However, we find no trend in the recall of plants from long-term associative memory, although this phenomenon is well established in studies on cognitive psychology. We suggest that such evidence should be considered in studies that use lists of medicinal plants because this temporal cognitive limit on the retrieval of knowledge affects data interpretation.

    Full Text Available Background & objectives: Mosquitoes transmit serious human health diseases, causing millions of deaths every year. Plants may be sources of alternative mosquito control agents. The present study was carried out to assess the role of larvicidal activities of the crude extracts of four plants viz. Alternanthera sessilis L. (Amaranthaceae, Trema orientalis L. (Cannabaceae, Gardenia carinata Smith. (Rubiaceae and Ruellia tuberosa L. (Acanthaceae against Culex quinquefasciatus Say in laboratory bioassay. Methods: Selective concentrations (0.5, 1 and 1.5% of crude extract of all four plant leaves were tested against I st to IV th instar larvae of Cx. quinquefasciatus. Log probit analysis (at 95% confidence level revealed the LC 50 values. Preliminary qualitative phytochemical analyses of crude extracts were also done. The lethal concentrations (% of crude extracts at 24 h against III rd instar larvae were also studied on non-target organisms. Result: In a 72 h bioassay experiment with crude extract, the highest mortality was recorded in 1.5 per cent extract. A. sessilis showed the highest mortality (76.7 % at 1.5 per cent crude extract against II nd instar larvae having LC 50 value of 0.35 per cent, followed by R. tuberosa (LC 50 =1.84%, G. carinata (LC 50 = 2.11 and T. orientalis (LC 50 = 2.95%. The regression equation showed a dose-dependent mortality, as the rate of mortality (Y was positively correlated with the concentration (X. Phytochemical analysis of the crude extract showed the presence of many bioactive phytochemicals such as steroids, alkaloids, terpenes, saponins, etc. No changes in the swimming behaviour and survivality of non-target organism were noticed at the studied concentrations. Interpretation & conclusions: Crude extract of the four selected plants showed larvicidal activity against Cx. quinquefasciatus. The extracts at the studied concentrations did not produce any harmful effect on non-target organisms.

    Conventional drugs have become expensive and therefore unaffordable to resource-limited farmers, causing farmers to seek low cost alternatives, such as use of medicinal plants. In this study, a survey was conducted in order to document information on medicinal plants used by farmers in the control of internal parasites in goats in the Eastern Cape Province. Structured questionnaires and general conversation were used to collect the information from farmers and herbalists. The survey revealed 28 plant species from 20 families that are commonly used in the treatment of gastro-intestinal parasites in goats. The plant family Asphodelaceae was frequent in usage, comprising 21.4% of the plants, and the Aloe was the most utilized species (50%). Leaves were the most frequently used plant parts (45.9%), and decoctions constituted the majority of medicinal preparations (70%). Medicinal plants are generally used in combination with other plants, and/or non-plant substances, but a few plants are used on their own. These medicinal plant remedies are administered orally, mainly by use of bottles and this is done twice in summer at intervals of one month, only once in winter and when need arises thereafter. Some of the mentioned plants have been reported in literature to possess anthelmintic properties, while others possess activities ranging from anti-inflammatory, analgesic, antimicrobial, purgative, anti-edema to immuno-regulation. If their safety and efficacy could be confirmed, these plants could form an alternative cost effective strategy in managing helminthiasis in the province.

    Full Text Available Background: The stem barks are the rich sources of tannins and other phenolic compounds. Tannins inhibited the growth of various fungi, yeast, bacteria and virus. Hence, ten stem barks of ethnomedicinally important plants were screened for antibacterial and antifungal activities against human pathogenic strains. Methods: Air-dried and powdered stem bark of each plant was extracted with 50% aqueous ethanol, lyophilized and the dried crude extracts were used for the screening against 11 bacteria and 8 fungi. Antibacterial and antifungal activities were performed according to microdilution methods by NCCLS. Results: The plants Prosopis chilensis, Pithecellobium dulce, Mangifera indica showed significant antibacterial and antifungal activities against Streptococcus pneumonia, Enterobacter aerogenes, Klebsiella pneumonia and Candida albicans with MIC of 0.08mg/ml. Pithecellobium dulce bark also showed significant antibacterial activity against Bacillus cereus. Conclusion: The bark of Pithecellobium dulce has more or less similar activity against the known antibiotic and may be considered as potent antimicrobial agent for various infectious diseases.

    Full Text Available The morbidity and mortality associated with snake bite is a serious health concerned especially in developing countries. The rural communities are the worst affected and where it is considered as one of the occupational health hazards especially related to agriculture industry. About 50,000 deaths are recorded per year as a result of snakebite. The scenario may sometimes deteriorate further because of Ineffectiveness and or complications of the anti snake venom as well as untimely interventions or lack of appropriate medications in venomous snakebite cases. The common poisonous snakes found in India are Cobra (Naja naja, Krait (Bangarus Caeruleus, Russell’s viper (Daboia russelli and saw scaled viper (Echis Carinatus. Over the years many attempts have been made for the development of snake venom antagonists from plants sources. Ethnobotanical data suggests that certain plant species are used traditionally all over the world to treat snakebite cases successfully. Randomness or the use of a variety of species in different families appears to be a feature of traditional snake bite treatments. Present article deals with the Traditional, ethno botanical and pharmacological review of certain plants utilized in the cases of snakebite.

    Alzheimer's disease (AD) has been linked with oxidative stress, acetylcholine deficiency in the brain, and inflammatory processes. In the northeast region of Brazil, various plants are used to treat several diseases associated with these processes; then an antioxidant test was performed with those plants in a previous work and twelve species with higher antioxidant activity were selected for AChE inhibition evaluation. The phenolic compounds content was determined by Folin–Ciocalteu test and flavonoid content with AlCl3 reagent using UV-visible spectrophotometry. The antioxidant activity was assessed analyzing the inhibitory activity against 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2-azinobis-3-ethylbenzothiazoline-6-sulfonate (ABTS) and by the β-carotene/linoleic acid system and acetylcholinesterase inhibition using qualitative and quantitative tests. The combination of better acetylcholinesterase inhibitory and antioxidant activities pointed out six species, in descending order, as the best potential sources of therapeutic agents against AD: Hancornia speciosa > Myracrodruon urundeuva > Copaifera langsdorffii > Stryphnodendron coriaceum > Psidium guajava > Mangifera indica. Besides, the phenolic compounds in the species probably contribute to these activities. However, further pharmacological studies to assess the specific applications of these plants against AD are required to confirm these results. PMID:28316633

    Bamboo plants play a significant role in traditional Asian medicine, especially in China and Japan. Biomedical investigations on the health-benefiting effects as well as toxicity of different parts and species of bamboo have been carried out worldwide since the 1960s, and documented a wide range of protective effects of bamboo-derived products, such as protection against oxidative stress, inflammation, lipotoxicity, cancer, and cardiovascular disease. Some of these products may interfere with male and female reproductive function, thyroid hormone metabolism, and hepatic xenobiotransformation enzymes. The diversity of bamboo species, parts of the plants available for medicinal use, and different extraction methods suggest that bamboo has great potential for producing a range of extracts with functional utility in medicine.

    Local medical systems are key elements of social-ecological systems as they provide culturally appropriate and locally accessible health care options, especially for populations with scarce access to biomedicine. The adaptive capacity of local medical systems generally rests on two pillars: species diversity and a robust local knowledge system, both threatened by local and global environmental change. We first present a conceptual framework to guide the assessment of knowledge diversity and redundancy in local medicinal knowledge systems through a gender lens. Then, we apply this conceptual framework to our research on the local medicinal plant knowledge of the Tsimane' Amerindians. Our results suggest that Tsimane' medicinal plant knowledge is gendered and that the frequency of reported ailments and the redundancy of knowledge used to treat them are positively associated. We discuss the implications of knowledge diversity and redundancy for local knowledge systems' adaptive capacity, resilience, and health sovereignty.

    Full Text Available Abstract Background The use of medicinal plants in the treatment of diseases has generated renewed interest in recent times, as herbal preparations are increasingly being used in both human and animal healthcare systems. Diarrhoea is one of the common clinical signs of gastrointestinal disorders caused by both infectious and non-infectious agents and an important livestock debilitating condition. Plateau State is rich in savannah and forest vegetations and home to a vast collection of plants upheld in folklore as having useful medicinal applications. There is however scarcity of documented information on the medicinal plants used in the treatment of animal diarrhoea in the state, thus the need for this survey. Ten (10 out of 17 Local Government Areas (LGAs, spread across the three senatorial zones were selected. Farmers were interviewed using well structured, open-ended questionnaire and guided dialogue techniques between October and December 2010. Medicinal plants reported to be effective in diarrhoea management were collected using the guided field-walk method for identification and authentication. Results A total of 248 questionnaires were completed, out of which 207 respondents (83.47% acknowledged the use of herbs in diarrhoea management, while 41 (16.53% do not use herbs or apply other traditional methods in the treatment of diarrhoea in their animals. Medicinal plants cited as beneficial in the treatment of animal diarrhoea numbered 132, from which 57(43.18% were scientifically identified and classified into 25 plant families with the families Fabaceae (21% and Combretaceae (14.04% having the highest occurrence. The plant parts mostly used in antidiarrhoeal herbal preparations are the leaves (43.86% followed by the stem bark (29.82%. The herbal preparations are usually administered orally. Conclusion Rural communities in Plateau State are a rich source of information on medicinal plants as revealed in this survey. There is need to

    Plants of the genus Terminalia are amongst the most widely used plants for traditional medicinal purposes worldwide. Many species are used for their antibacterial, antifungal, antiprotozoal, antiviral, antidiarrhoeal, analgesic, antimalarial, antioxidant, antiinflammatory and anticancer activities. Wound healing and cardiovascular effects have also been credited to some species. Many Terminalia species have multiple beneficial effects for multiple diseases and ailments. Indeed, the Indian species Terminalia chebula is known as the king of plants in Ayurveda due to its broad range of medicinal uses. However, apart from the reported ethnopharmacological uses of many Terminalia species, surprisingly few studies have rigorously examined this important genus for their medical properties/mechanisms and phytochemistry. This is likely due to the high tannin content common to many Terminalia species and the perception that these tannins may be responsible for much of their beneficial properties. As the complexities of tannins make them poor candidates for drug design, most interest in Terminalia species has been for their pharmacognostic and nutraceutical value and they have often been overlooked as potentials for drug discovery. However, recent reports have identified many other interesting phytochemicals and demonstrated that these may be responsible for several of the reported bioactivities of the Terminalia species used in traditional medicinal systems. The last decade has seen a large increase in the number of studies into the use of Terminalia species as therapeutic agents. Several species used in Ayurvedic medicine (Terminalia arjuna, Terminalia bellerica, Terminalia catappa, T. chebula) in particular have received much recent attention. Similarly, recent reports have also highlighted the medicinal potential of species from Africa, Australia and the Americas. The aim of this report is to summarise the recent research into the medicinal properties, phytochemistry and

    Full Text Available Abstract An ethnopharmacological survey was carried out to collect information about the use of six medicinal plants in the regions around Siby and Dioila, Mali. The plants investigated were Biopyhtum petersianum, Cola cordifolia, Combretum molle, Opilia celtidifolia, Parkia biglobosa and Ximenia americana. More than 60 medical indications were reported for the use of these plants in traditional medicine. The most frequently reported ailments were malaria (25.6%, different types of pain (14.0% and dermatitis (7.4%. The main forms for preparation were decoction (58.1% and powdered plant material (28.4%. The most frequent used plant parts were leaves (37.7% and stem bark (18.6%. The healers' consensus for the main indications is fairly high for the four plants B. petersianum, C. cordifolia, C. molle and O. celtidifolia, and this supports the traditional use of these plants. However for P. biglobosa and X. americana the healers' consensus is less consistent and it is more difficult to draw conclusions about the most important traditional use of these two plants.

    Diabetes mellitus, a metabolic disease characterized by high blood glucose levels (hyperglycemia) due to defects in insulin secretion, or action, or both, is a debilitating disease leading to other complications and death of many people in the world. Some of the medicinal plants implicated in the herbal recipes for the treatment of diabetes in Nigeria have been reported. Additional medicinal plants used for the treatment of diabetes in Nigeria are presented in this work. These medicinal plants are becoming increasingly important and relevant as herbal drugs due to their use as antioxidants, nutraceuticals, food additives and supplements in combating diabetes. Elemental compositions of these anti-diabetic medicinal plants were determined using PIXE technique. The 1.8 MV collimated proton beam from the 2.5 MV AN 2000 Van de Graaff accelerator at Istituto Nazionale di Fisica Nucleare (INFN), Laboratori Nazionali di Legnaro (LNL) Legnaro (Padova) Italy was employed for the work. The results show the detection of twenty-one elements which include Mg, P, Ca, K, Mn, Cu, Zn, S, Cr, Co, Ni and V that are implicated in the regulation of insulin and the control of the blood-sugar levels in the human body. The entire plant of Boerhavia diffusa, Securidaca longipedunculata stem, leaves of Peperomia pellucida, Macrosphyra longistyla, Olax subscorpioidea, Phyllanthus muerillanus, Jatropha gossypifolia, Cassia occidentalis, Phyllanthus amarus, and leaf and stem of Murraya koenigii, which have high concentrations of these elements could be recommended as vegetables, nutraceuticals, food additives, supplements and drugs in the control and management of diabetes, if toxicity profiles indicate that they are safe. However, significantly high contents of Al and Si in the entire plant of Bryophyllum pinnatum, and As, Cr, and Cu in Ocimum gratissimum leaf suggest that these plants should be avoided by diabetic patients to prevent complications.

    Full Text Available The use of medicinal plants has been decreasing gradually. Our main objective was to determine whether young people today are still familiar with medicinal plants, and whether traditional knowledge, which forms part of the cultural heritage, has been lost or is still being passed on to new generations. In our study, we found that the majority of 19-year-olds used medicinal plants occasionally. They mostly buy dried plants or products based on medicinal plants; they rarely grew plants themselves. Their general knowledge concerning the use and effects of using these plants was not satisfactory. Students were only able to identify correctly a few medicinal plants, and most were not able to recognize poisonous plants. It was proposed that more time in school should be devoted to this topic because pupils did show interest in medicinal plants. This could be in the form of an elective module in the frame of an open curriculum that would also include growing plants in a school garden.

    Ethnopharmacological relevance Traditional knowledge of medicinal plant use in many regions of Papua New Guinea and the Autonomous Region of Bougainville is poorly described and rapidly disappearing. A program initiated by the University of Papua New Guinea to systematically document and preserve traditional knowledge of medicinal plant use was initiated with WHO help in 2001. Aim of the study To document and compare medicinal plant use in the Siwai and Buin Districts of the Island of Bougainville. Siwai and Buin districts represent two adjacent geographic regions of differing language traditions. Materials and methods This report is a combination of two University of Papua New Guinea reports generated using a University of Papua New Guinea and Papua New Guinea Department of Health approved survey questionnaire “Information sheet on traditional herbal reparations and medicinal plants of Papua New Guinea”. Results Although Siwai and Buin Districts are adjacent in Southern Bougainville, there is considerable variation in the specific plants used medicinally and the specific uses of those plants that are used commonly in the two regions. In addition, many of the plants used in the region are widely distributed species that are used medicinally in other settings. Nevertheless, the high endemicity of plants and the extraordinary cultural diversity in the Autonomous Region of Bougainville has yielded description of the medicinal use of many plants that have not previously been reported in the wider scientific literature. Conclusions Efforts to document and preserve traditional knowledge of plant use in Papua New Guinea have yielded important new records of plants with potential application in the provision of health care for a developing nation with an under developed Western style rural health care system. This report documents substantial commonality in the general modes of medicinal plant preparation and in the health care applications of plant use in the Siwai

    With one of the oldest surviving cultures in the world, Australian Aboriginal people have developed immense knowledge about the diverse Australian flora. Western scientific investigation of some Australian Aboriginal medicinal plants has demonstrated interesting pharmacological activities and chemistry, however the majority of these species have not yet been extensively examined. We argue that research that is locally initiated and driven by Indigenous traditional owners in collaboration with Western scientists has significant potential to develop new plant-based products. Locally driven medicinal plants research in which traditional owners work as researchers in collaboration with University-based colleagues in the investigation of medicines rather than "stakeholders" or "informants" is one model that may be used in characterising plants with the potential to be developed into sustainable plant-based medicinal products with commercial value. Our team has taken this approach in research located both on traditional homelands and in the laboratory. Research being conducted by the University of South Australia and Chuulangun Aboriginal Corporation has led to patent filing for protection of intellectual property associated with novel compounds and extracts with the potential for development through cosmetic, complementary medicine and pharmaceutical routes. Ongoing research is examining the commercial developmental pathways and requirements for product development in these spaces. This review will address the opportunities that might exist for working in partnership with Australian Indigenous communities, some of the scientific knowledge which has been generated so far from our work together and the lessons learnt since the inception of the collaboration between the Chuulangun Aboriginal Corporation and scientists from the University of South Australia.

(Arecaceae, and Doronicum glaciale (Wulfen Nyman (Asteraceae are of ethnomedicinal importance in Persian folk medicine and are widely used to treat infectious diseases. The aim of the present study was to investigate the antimicrobial properties of these herbal medicines to prevent misadministration. Methods: Antifungal and antibacterial (Gram-positive and Gram-negative activities of the petroleum ether, dichloromethane and ethanol fractions obtained from oleo-gum-resin of C. habessinica and B. sacra, spathe of P. dactylifera and roots of D. glaciale were evaluated against standard species and clinical antibiotic resistant isolates using broth microdilution method. The fractions were tested at concentrations of 0.5 to 256 µg/mL.Results: The petroleum ether fraction of C. habessinica oleo-gum-resin exhibited the most anti-Candida activity with MIC50 of 0.5-16 µg/mL. The growth of C. glabrata and C. tropicalis was inhibited by the ethanol fraction of C. habessinica oleo-gum-resin with MIC50 of 1-16 μg/mL. C. glabrata was the most susceptible species. Among the tested fractions, only the petroleum ether fraction of C. habessinica oleo-gum-resin had an inhibitory effect on Aspergillus spp. with a MIC50 of 8-32 µg/mL. None of the fractions exhibited antimicrobial activity against the Gram-positive and Gram-negative bacteria at concentrations of 0.5 to 256 µg/mL. Conclusions: The sensitivity of fungi and bacteria to natural antimicrobials varies widely within species and it is essential to consider the sensitivity of the strains to prevent resistance.

    This study was to compare the total phenolic (TP) content in extracts from eleven plant materials collected at different geographical locations in Kenya, Nigeria, and USA. These plants have been selected because the majority of them are highly pigmented, from yellow to purple, and would therefore have economic value in industries for producing antioxidants and surfactants. Two of them were collected from the industrial and domestic waste outlets. Each analysis was achieved using the Folin-Ciocalteau technique. The order of decreasing phenolic acid content as gallic acid concentration (mg/g dry weight) was Prunus africana (55.14) > Acacia tortilis (42.11) > Khaya grandifoliola (17.54) > Curcuma longa (17.23) > Vernonia amygdalina (14.9)> Russelia equisetiformis (14.03) > Calendula officinalis (7.96) >Phragmites australis (control) (7.09) > Rauwolfia vomitoria (6.69) > Phragmites australis (industrial) (6.21) > Cnidoscolus aconitifolius (5.6).
