制订胃炎康胶囊质量标准 ,对白芍、桂枝进行了薄层色谱鉴别 ,用薄层扫描法测定了盐酸小檗碱的含量 ,结果 :平均回收率 98.6 % (RSD=1.9% ,n=6 ) ,标准曲线 r=0 .9998重复性 RSD=2 .0 5 % (n=6 ) ,同板精密度 RSD=1.6 2 % (n=6 )。方法稳定、可靠 ,可作为该制剂的质量控制方法之一
The quality standards for Weiyankang capsules were formulated. TLC and cassia twigs were identified by TLC. The content of berberine hydrochloride was determined by TLC scanning. The results showed that the average recovery was 98.6 % (RSD=1.9%, n=6). The standard curve r=0.9998 repeatability RSD=2. 0 5 % (n=6) and the same-plate precision RSD=1.6 2 % (n=6). The method is stable and reliable and can be used as one of the quality control methods of the preparation
