本文用聚酰胺薄膜做固定相,将固经丸中有效成份黄芩甙分离,洗脱后在278nm 波长处,用紫外分光光度法测定其含量。回收率95.20%,CV=2.3%。
This article uses a polyamide film as a stationary phase, separates the active ingredients of the solid-medium pills from the astragalus membranaceus, and measures its content by ultraviolet spectrophotometry at a wavelength of 278 nm after elution. The recovery rate was 95.20% and CV=2.3%.
