测定安国县10个村引种黄芪药材中黄芪甲苷含量,平均值为0.199%,比传统道地黄芪高2倍,比《中国药典》标准(不得少于0.04%)高近4倍,但外观质量难以相比,10个村黄芪药材中砷、汞、铅、镉、镍、钴等 6种元素的平均值分别为 0. 244、0. 009、1.731、0. 036、0. 214、0. 302 μg/g,与土壤中6种元素的比值即富集系数≤0.5。

[Abstract]
The astragaloside contents in the root of Astragalus membranaceus (Fisch.) Bunge (RAM) from ten villages of Anguo county, Hebei province were determined. The average value was 0.199% which was 2 and 4 times higher, respectively, than that of the genuine geo-herbal RAM and the standard (0.04%) stipulated in Chinese pharmacopoeia (Part Ⅰ, 1995 ed.). But these results do not mean that their quality is better than the genuine RAM because their appearance, texture, odor and taste etc. were not as good. The average value of trace elements As, Hg, Pb, Cd, Ni, Co in the cultivated variety were respectively 0.244, 0.009, 1.731, 0.036, 0.214, 0.032 μg/g, less than 0.5 value in the soil.
