黄芪根、茎叶黄芪皂苷含量的测定

Determination of Saponin Content in Root, Stem and Leaf of Astragalus membranaceus

利用比色法对黄芪根、茎叶黄芪皂苷的含量进行了测定。结果表明:黄芪根中总皂苷含量为0.2616％。黄芪甲苷含量为0.085％;黄芪茎叶总皂苷含量为0.2162％。黄芪甲苷含量为0.052％。黄芪茎叶皂苷可替代根入药。

Saponin content in roots, Stems and leaves of Astragalus membranaceus was determined by comparing their colors. Results indicated that in roots of Astragalus membranaceus, content of saponins is 0. 261 6 %, and that of astragaloside Ⅳ is 0. 085 %. In leaves and stems of Astragalus membranaceus, content of saponins is 0.2162%, and that of astragaloside Ⅳ is 0.052%. Saponins of stems and leaves of Astragalus membranaceus can be used as medocone instead of roots of Astragalus membranaceus.
