天冬类药材中洋菝契皂苷元的含量测定

Detennination of Sarsasapogenin in "Tian Dong" by TLCS

天冬类药材中皂苷类成分种类较多,我们选择其共有的皂苷元洋菝契皂苷元为质量评价指标成分,利用薄层扫描法对天冬类中药材中洋菝契皂苷元的含量进行了分析测定。结果表明,来源于7种天冬属植物块根的12件商品药材样品中均含有以洋菝契皂苷元为甙元的甾体皂苷,皂苷元含量与天冬药材的植物来源无明显的相关性,且皂苷元的含量与商品等级成反比。

This paper reported the determination of sarsasapogenin in 12 samples from 7 species and varieties of Asparagus genus whose commercial name is 'Tian-Dong'(Radix Asparagi), Asparagus cochichinensis(Lour.) Merr, A. cochichinensis (lour.)Merr. var. gaudichau-dianus (Kunth) X. D. Luo and G. J. Xu, A.taliensis Wang et Tang, A. munitus'Wang et Tang, A. myriacanthus Wang et S. C. Chen, A. meioclados Levl and A. trichoclados (Wang et Tang) Wang et S. C. Chen by TLCS. The results showed that it was no pertinence between content of sarsaspogenin with the species, and the content of sarsasapogenin in the tuberous roots was inverse ratio with the commercial grande in same species.
