五种云南黄芪属植物的生药学研究

Pharmacognostic Studies of Five Astragalus Species from Yunnan

目的对五种云南黄芪属药用植物俅江黄芪、肾形子黄芪、厚叶黄芪、类芒齿黄芪和石生黄芪进行系统的生药学研究。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的性状、显微鉴别和HPLC化学成分图谱进行研究。结果五种黄芪属植物的根横切面、粉末特征、化学成分之间有一定差异。结论实验结果可为上述植物的鉴定、质量标准的制订和进一步开发利用提供理论依据。

Objective For the better utilization of the plentiful Astragalus resource from Yunnan, pharmacognostic studies were systematically performed on five Astragalus plants including Astragalus chiukiangensis, A. skythropos, A. crassifolius, A. campt- odontoides, and A. sctxorum. Methods Regular pharmacognosy methods and HPLC analysis were used to examine the plalxts for the medicinal parts traits, characters of microscopic identification, and the major chemical constituents. Results Differences a- mong the five Astragalus plants were observed in root cross - section, powder characteristics, and chemical constituents. Conclu- sion Experimental results from this study laid the theoretical basis for pharmacognostic identification, formulation of quality stand- ards, and development and utilization of Astragalus plants.
