广西黄花倒水莲资源调查及总皂苷含量比较

Resources investigation and determination of total saponin content in Polygala fallax from Guangxi

对广西黄花倒水莲(PolygalafallaxHemsl.)资源现状进行了调查,并采用香草醛 高氯酸比色法测定了不同产地黄花倒水莲不同部位的总皂苷含量,基本弄清了黄花倒水莲在广西的资源分布、生长环境及目前民间药用情况。总皂苷含量测定结果表明:根、茎和叶中总皂苷含量存在较大差异,依次为:根>叶>茎;各产地间含量差异较小。

Resources of Polygala fallax Hemsl. in Guangxi was investigated. The content of total saponins in roots, stems and leaves of P. fallax from different collection areas were determined by vanillinperchloric acid spectrophotometric method. The resources distribution, growth environmental condition and native herb use of P. fallax in Guangxi were claritied. The results indicated that the content of total saponins in roots, stems and leaves were different significantly. The content of total saponins in roots was higher than that in leaves and then stems. The contents of total saponins in different collection areas were similar.
