7种有代表性云南黄芪属植物药材的生药学研究

Pharmacognostical Study on Seven Species from Astragalus Genus in Yunnan

目的:对黄芪属4个亚属7种植物根进行系统的生药学研究,为其鉴别及开发利用提供科学依据。方法:采用生药学常用实验方法和HPLC技术对这些植物样品药用部位根的性状、显微鉴别和HPLC化学成分图谱进行研究。结果:7种黄芪属植物的根横切面、粉末特征、化学成分之间有一定的差异。结论:该研究为黄芪属植物的进一步深入研究提供了实验基础。

Objective：For the identification and utilization of the Astragalus plants from Yunnan, pharmacognostical studies were systematically performed for seven Astragalus plants which were selected from four subgenera of Astragalus genus. Methods ： Standard pharmacognosy methods and HPLC method were adopted, and microscopic characteristics and major chemical constituents of the test plant samples were compared. Results：There were differences in root transverse section, powder and chemical constituents of the seven Astragalus plants. Conclusion ： This study can provide the pharmacognosy experimental basis for the future study of Astragalus plants.
