贵州药用植物资源的调查和开发利用研究(续完)

Objective: To gain a clear idea of the resources of medicinal plants and their pharmaceutical identification in Guizhou , China, and to conserve, develop,and uilize them effectively.Method: Investigation on the spot with a statistical analysis. The technical route is“ Investigation and identification →Conservation and development →Method, technology and ways for protection, propagation and utilization →GAP cultivated pilot and assessment of medicinal materials and their products →Comprehensive evaluation and results". Result: According to the incomplete statistics, there are 3924 varieties of medicinal materials from plants, accounting for 91.47% of the total in Guizhou. Among them there are 275 families, 1384 genera and 2987 species of vascular bundle plants, accounting for 43.1% of all species. There are 200 species of pteridophyta and 2802 spermatophyta. Conclusion: Investigation of wild medicine species has been proceeded, as well as introduction and research of their propagation techniques and production. Guizhou is rich in medicinal plant resources. However, their species and population are reducing progressively. Effective measures must be taken to protect the germ plasma resources and put them into rational uses for the utilization and sustainable development. Rare and endemic medicine species must be introduced for conservation, propagation and realization of GAP pilot cultivation. Resources must be used in an economical way and products must be made with a high technological content.

对实施中药材GAP的几点建议

GAP的现状及实施GAP的关键GAP与SOP.GAP是Good Agriculture Practice of Medicinal Plants and Animals 的简称,即"中药材生产质量管理规范".它和GLP、GCP、GMP、GSP形成了一套较为完备的质量管理规范体系.GAP涉及产地环境生态、种质和繁殖材料、栽培与饲养管理、采收及产地加工、包装运输与贮藏、质量管理、人员及设备、文件及档案管理内容,其目的是保证安全、有效、稳定的中药材的规范化生产.

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.

Herbal approach to the treatment of diabetes

Objective:To investigates the use of medicinal plants for the treatment of diabetes in Birnin Gwari Local Government Area of Kaduna State.Nigeria.Methods:Structure questionnaire were administered to traditional healer,herb traders,farmers and civil servants in the Local Government Area.Descriptive analysis such as frequency tables and percentages were used for the analysis.Results:The result revealed that there are six families of plants of majorly forest trees identified for treating diabetes in the study area.Medicinal plants such Moringa oleifera(Zogale),Allium sativum(Tafarnuwa),Citrus aurantifolia(Lemun tsami),Tamarindus indica(Tsamiya),Khaya senegalensis(Madaci),and Phyllanthus recticulatus(Kalinbo)were identified for the treatment of diabetes.Some of the medicinal plants are used as single while some are conbined with other plants before use.Total cure vary from one day to one month,depending on the choice or combination of plants.Conclusion:The results indicated that there is need to create awareness of environmental conservation and protection of biodiversity in the study area.
