不同来源黄芪中黄芪总皂苷含量比较研究

Comparation of the Contents of Astragali Total Saponins among Different Origins

目的:比较全国不同来源黄芪中总皂苷含量。方法:采用紫外分光光度法测定黄芪总皂苷含量,以黄芪甲苷为对照品,测定波长为541 nm。结果:全国黄芪总皂苷平均含量为20.18 mg·g-1,蒙古黄芪总皂苷平均含量为21.06 mg·g-1,膜荚黄芪总皂苷平均含量为19.37 mg·g-1;野生黄芪药材总皂苷平均含量为21.33 mg·g-1,人工种植黄芪药材总皂苷平均含量为19.06 mg·g-1,半野生栽培黄芪药材总皂苷平均含量为18.97 mg·g-1。结论:不同来源黄芪药材总皂苷含量具有明显差异。

Objective： To investigate the contents of astragali total saponins （ATS） in Astraglus among different origins. Methods： They are measured by the method of ultraviolet spectrophotometry, Astragaloside IV was used as index,the test wavelength was 416 nm. Results： The ATS average content of the whole country was 20. 18 mg＇g-1,the ATS content in astragali radix from A. membranaceus（ Fisch. ）Bge. var. mongholicus（ Bge. ）Hsiao was 21.06 mg＇g-1, from A. membranaceus （ Fisch. ） Bge. was 19.37 tug. g- ~, the content of ATS in wild, cultured, semi-wild samples were 21.33,19. 06 and 18.97 mg＇g-1 respectively. Conclusion： The contents of ATS in Astragalus among different habitats have obvious difference.
