采用聚酰胺薄膜──薄层扫描法,以黄芩甙为定量指标,测定辛芩胶囊中黄芩甙含量。回归方程为Y=9312.5X+246.25,r=0.9992,作品平均加样回收率98.57%,RSD为2.63%。本方法简便、快速、重现住好,效果较满意。
Using polyamide thin film-thin-layer scanning method, Astragalus membranaceus was used as a quantitative index to determine the content of jaundice in Xinqi capsules. The regression equation was Y=9312.5X+246.25, r=0.9992. The average sample recovery rate was 98.57% and the RSD was 2.63%. The method is simple, rapid, and reproducible, with satisfactory results.
