目的比较不同产地、不同生境条件膜荚黄芪和蒙古黄芪药材中黄芪甲苷、总黄酮及总多糖的含量。方法HPLC-ELS法测定黄芪甲苷的含量,比色法测定总黄酮的含量,硫酸-苯酚法测定黄芪总多糖的含量。结果野生黄芪中总黄酮和总多糖含量高于栽培黄芪,不同地区栽培黄芪的有效成分含量相差不多,旱地栽培黄芪有效成分含量高于水地黄芪。结论通过对不同产地、不同生境黄芪有效成分含量的比较,为黄芪的栽培提供理论依据。

Object To compare the content of astragaloside Ⅳ,total flav onoids, polysaccha rides in Astragalus membranaceus(Fisch.)Bge.and Astragalus membranaceus(Fisch.)Bg e.var.mongholicus Hsiao Bge.from different productive areas.Methods Ast ragaloside Ⅳ was determined by HPLC-ELS, total flavonoids by spectrophotometer and polysaccharides by sulfuric acid-phenolmethod.Results Content of total flavonoids and polysaccharides in wildspecies was higher than that in culti species of Radix Astragali,content of active compounds was almost the same in species from different productive areas and content of active compound in dry-cultiv ated Radix Astragali washig her than that in water-cultivated one. Conclusion This study provided theoretical basis for cultivation of Radix Astragali in different localities and habitats.
