As in most peasant cultures medicinal plants are a very important resource for the Nahua of the Sierra de Zongolica (Mexico). Documentation of the current indigenous medicinal uses of 203 plants in this region was conducted during 18 months of fieldwork. The 816 individual reports documented were divided into nine groups of indigenous uses. The frequency of usage of the individual plants reported was employed in the analysis of the ethnobotanical importance of the respective plants. Plants cited more frequently in a group of indigenous uses are regarded as of greater ethnobotanical importance than those cited only by a few informants. Data on phytochemistry, pharmacology and ethnobotany from the scientific literature were used to evaluate possible biological or pharmacological and toxicological effects of some particularly important plants. For most plants detailed studies on these actions are still lacking, which would allow a conclusive evaluation. This ethnobotanical evaluation forms the basis for such studies which have been started on some plants, and for better understanding their potential as minor economic products of the region. These uses may also give incentives to the conservation of the local biodiversity.  相似文献

The present paper represents the ethnopharmacological survey of Sudhan Gali, Kashmir, Pakistan. The study revealed that 12 plant species belonging to 11 families were used for the treatment of stomach, diabetes and ophthalmic diseases by the local people in Sudhan Gali. Achillea millefolium , Aconitum heterophyllum, Berberis lycium, Polygonum amplexicaule, Mentha longifolia, Paeonia emodi, Plantago lanceolata were locally used for stomach related problems treatment; Berberis lycium, Skimmia lareola, Solanum dulcamara for diabetes and Geranium wallichianum, Artemisia vulgaris, Solanum dulcamara, and Corydalis crassifolia used for the treatment of ophthalmic diseases. Two species Berberis lycium and Solanum dulcamara have multipurpose value. Former is used to treat stomach as well as diabetes while latter is used to treat not only to diabetes but also ophthalmic diseases. According to IUCN categories , out of these 12 plant species collected and marketed, Polygonum amplexicaule and Paeonia emodi are endangered, Aconitum heterophyllum; Berberis lycium species are vulnerable while Plantago lanceolata and Skimmia lareola species are rare.The availability of these medicinal plants has decreased during the past 20 years and these are facing a drastic biotic pressure due to their extensive usage and non-scientific methods of collection. It is quite evident that these valuable native medicinal plants species are going to decline in number and ultimately will become extinct if no timely proper conservation strategies are adopted.  相似文献

The aim of the present study was to quantify selected phenolic compounds, determine antioxidant activity and enzyme inhibitory effects of the aerial parts of Alkanna trichophylla Hub.-Mor. (A. trichophylla) and Convolvulus galaticus Rost.ex Choisy (C. galaticus) extracts prepared by homogenizer-assisted extraction (HAE), maceration (MAC) and infusion techniques. This is the first time such study has been designed to validate the phytochemical composition and bioactivity of these plants. Multivariate analysis was conducted on collected data. Rutin and caffeoylquinic acid derivatives were the most significant compounds in A. trichophylla and C. galaticus, respectively. The highest antioxidant activity of A. trichophylla was mostly exhibited by HAE/methanolic extracts as determined by DPPH, ABTS, FRAP (51.39, 112.70 and 145.73 mg TE/g, respectively) and phosphomolybdenum (2.05 mmol TE/g) assays. However, significant antioxidant activities varied within the extracts of C. galaticus. HAE/methanolic extract of A. trichophylla significantly depressed AChE (2.70 mg GALAE/g), BChE (5.53 mg GALAE/g) and tyrosinase (26.34 mg KAE/g) activities and that of C. galaticus inhibited AChE (2.04 mg GALAE/g), tyrosinase (31.25 mg KAE/g) and α-amylase (0.53 mmol ACAE/g) activities significantly. We concluded that HAE was the most efficient extraction technique as high yield of compounds and promising bioactivities were recorded from extracts prepared. Multivariate analysis showed that types of solvents influenced recovery of compounds and biological activities. This research study can be used as one methodological starting point for further investigation on these plants as all results are clearly promising and open the door to further research challenges such as cytotoxicity evaluation, molecular docking analysis, and more screening of pharmacological actions.  相似文献

This study focuses on knowledge of medicinal plants among the Caiçaras (rural inhabitants of the Atlantic Forest coast, Brazil). In particular, we examine the use of medicinal plants according to sex and age to reveal general patterns of Caiçara knowledge and use of plant resources. Data collected through 449 interviews at 12 Caiçara communities (Rio de Janeiro and São Paulo coastal sites) include citations of 249 plants and identification of 227 species. We show the importance of introduced as opposed to native plants and of key individuals for the conservation of the Caiçaras-Atlantic Forest.  相似文献

Material ascribed to the genus Callulina from north‐east Tanzania and south‐east Kenya is assessed. Three new species of Callulina are described from the North ( Callulina laphami sp. nov. ) and South ( Callulina shengena sp. nov. and Callulina stanleyi sp. nov. ) Pare Mountains in Tanzania. The species are diagnosed based on morphological, acoustic, and molecular data. A new key to the species of Callulina is provided. Based on an interpretation of the International Union for Conservation of Nature (IUCN) red list, we suggest that the three species will qualify as critically endangered, because of their small distributions and the ongoing threat to their habitat. We reveal the high local endemism of Callulina in the northern part of the Eastern Arc Mountains, with each species restricted to no more than one mountain (fragment) block. This high local endemism in Callulina is probably widespread across the Eastern Arc, raising further conservation concern for this group of amphibians. Based on new molecular phylogenetic data for Callulina, we discuss biogeographical relationships among north‐east Tanzanian mountains, and evolutionary patterns in Eastern Arc breviciptids. © 2010 The Linnean Society of London, Zoological Journal of the Linnean Society, 2010, 160 , 496–514.  相似文献

药用植物资源利用的一种分析模型   总被引:1,自引:0,他引:1  
在系统分析药用植物资源利用的各方面因素基础上,以资源利用模式为研究切入点,提出了一个基于资源利用模式和模式形成路径的分析模型(Pattem—Path Model),用于整体分析某一药用体系中植物资源的开发利用水平和发展过程。应用该分析模型对2005版中国药典使用的药用植物资源(549种高等植物)进行了分析,结果表明:中国药典中应用的药用植物,其资源利用发展较成熟(供应持续性良好的植物资源占79%,暂不能持续供应的占21%);但是资源利用的发展过程不尽合理(部分植物资源的栽培开展滞后于野生资源的枯竭,占40%)。该结论与已有定性评价观点相一致,并量化地体现出资源利用的发展水平和发展过程,能够推广应用到其他药用体系的资源利用分析,为药用植物资源的利用管理提供决策依据。  相似文献

Potential probiotic bacteria can be used as a biotherapeutic agent and a sustainable alternative to antibiotics, as an anti-oxidative, anti-inflammatory, and anti-diabetic agent without causing any serious side effects. Mostly human-friendly Lactic acid bacteria (LAB) have been isolated from the animal-human origin to be used as biotherapeutic agents or to produce useful metabolites (nutraceutical). However, less information is known about the role of medicinal plants associated LAB as biotherapeutic agents. The isolation of 115 human-friendly Lactobacillus strains was done from the rhizosphere of the medicinal plants Ocimum tenuiflorum, Azadirachta indica, Ficus carica. The obtained bacteria were then tested for their safe status before being using it for a beneficial purpose. Out of 115 strains, 29 (25%) were negative for blood hemolytic activities. Among these 29 isolates, three isolates did not show a breakdown of gelatin and were recognized as safe. Antibiotic resistance assay showed resistance of two of them against antibiotics discs of Streptomycin (10 µg), Ciprofloxacin (20 µg), Vancomycin (30 µg), Metronidazole (10 µg), Ampicillin (5 µg), Chloramphenicol (30 µg), Kanamycin (30 µg), Erythromycin (15 µg), Penicillin (10 µg) and Tetracycline (30 µg). The bacterial isolate (T-2) was found safe that was identified as Lactobacillus agilis by sequence analysis of 16 s rRNA gene and processed in vitro as an anti-bacterial, anti-oxidant, anti-diabetic, and anti-inflammatory agent. Free radical scavenging activities and inhibition of α-amylase activities for Lactobacillus agilis were found relative to standard drug values as 68% and 73% and 51.3% and 65.3%, respectively. The in-vitro anti-inflammatory assay showed 61.6% (Lactobacillus agilis) while showed 69% (aspirin) activity for denaturation albumin protein. The results suggested that Lactobacillus agilis can be used as a potential probiotic strain as well as can be used to produce nutraceuticals.  相似文献

We have screened a number of plants from the Indian soil for potential antioxidant properties out of which fifteen extracts were found to be positive. Leaves/bulk from the plants were crushed and extracted with organic solvents by three different ways. The first group of plants were extracted with CHCL3:CH3OH (2:1), evaporated, partitioned between petroleum ether and methanol (9:1), aqueous methanolic part re-partitioned between methanol: H2O (4:1) and dichloromethane. Methanol was evaporated from the aqueous methanolic part and extracted with n-butanol. The second group of plants were extracted with methanol followed by partitioning between petroleum ether and CH3OH. The rest of the extraction procedure was the same as above. A third extraction procedure was used for Ocimum sanctum which after extraction with CHCL3:CH3OH (2:l), partitioned between CCL4 and CH3OH:H2O (9:1). Aqueous methanolic part was repartitioned between CH3OH:H2O (4:1) and CHCI3 and CHCI3 soluble part was used for the study. Free radical scavenging activities of the plant extracts were examined by chemiluminescence method. Peroxyl radical was generated from 2,2'-azobis(2-amidinopropane) dihydrochloride (AAPH), superoxide radical (O2--) from xanthine/xanthine oxidase (XO) and hydroxyl radical (OH) from Xanthine/XO/ FeClJ EDTA. In addition, O2-- and OH. scavenging activities were also determined by cytochrome C reduction and deoxyribose oxidation methods, respectively. The results of this study demonstrate that these plant extracts possess potent antioxidant activities.  相似文献

A new species of sengi, or elephant-shrew, is described. It was discovered in the northern Udzungwa Mountains of Tanzania in 2005. Sengis (Order Macroscelidea, super-cohort Afrotheria) include four genera and 15 species of mammals that are endemic to Africa. This discovery is a significant contribution to the systematics of this small order. Based on 49 camera trap images, 40 sightings and five voucher specimens, the new sengi is diurnal and distinguished from the other three species of Rhynchocyon by a grizzled grey face, pale yellow to cream chest and chin, orange-rufous sides, maroon back and jet-black lower rump and thighs. The body weight of the new species is about 700 g, which is 25–50% greater than any other giant sengi. The new Rhynchocyon is only known from two populations that cover about 300 km2 of montane forest. It has an estimated density of 50–80 individuals km−2. This discovery has important implications for the conservation of the high biodiversity that is found in the forests of the Eastern Arc Mountains.  相似文献
