建立了参芪胶囊中人参皂甙 Rg1含量的薄层扫描测定方法。展开剂采用氯仿 -甲醇 -水 (13∶ 7∶ 2 )在 10℃以下放置过夜的下层溶液 ,在该条件下 ,黄芪皂甙不干扰测定。平均回收率为 98.9% ,RSD值为1.18% A thin-layer scanning method for determining the content of ginsenoside Rg1 in Shenqi capsules was established. The developing solution was a lower solution of chloroform-methanol-water (13:7:2) kept at a temperature of less than 10°C overnight. Under this condition, the astragaloside did not interfere with the assay. The average recovery rate was 98.9% and the RSD was 1.18%
