摘要

目的:测定藏药翼首草不同药用部位总皂苷的含量

并比较其不同部位之间的差异。方法:以熊果酸为对照

用5%的香草醛-冰醋酸及高氯酸进行显色

在540 nm波长下运用紫外分光光度法对翼首草不同部位总皂苷含量进行测定。结果:在0.058 2～0.203 8 mg熊果酸的吸光度与含量线性关系良好（r=0.999 1）。平均回收率97.06%

RSD 1.93%。结论:翼首草地上部分总皂苷平均含量高达5%

结合目前藏医院用药情况及药理研究现状

在保护资源的前提下

同时又不影响其疗效的情况下

建议以地上部分为其入药部位。

Abstract

Objective:To determine the total saponins from P.hookeri in different medicinal part and compare the differences in the different parts.Method: Ursolic acid was selected as control article.Coloration was used with 5% vanillin and perchloric acid.The content of total saponins from P.hookeri in different medicinal parts was determined at 550 nm by UV.Result: Ursolic acid was linear within the range of 0.058 2-0.203 8 mg;the correlation coefficient r=0.999 1.The average recovery was 97.06%

RSD 93%.Conclusion: The average content of total saponins from aerial parts was up to 5%.Combining Tibetan hospital drug use and pharmacological research status

in the premise of resource protection

and do not affect its curative effect at the same time

it is recommended that the aerial part of P.hookeri should be its medicinal part.
