目的 :控制清肠合剂的质量。方法 :采用薄层色谱法对方中的枳壳、大黄进行鉴别 ,并以薄层扫描法对主药中的大黄素进行定量。结果 :鉴别项下的阴性对照无干扰 ,方法专属性强 ;含量测定中 ,大黄素在 0 2 2 8μg～ 1 14 0 μg范围内线性关系良好 (γ =0 9993) ,回收率为 10 0 9% ,RSD为 2 96 %。结论 :本质量标准可有效控制清肠合剂的质量。
Objective: To control the quality of Qingchang Mixture. Methods : Tincture and rhubarb in the other party were identified by thin layer chromatography. The emodin in the main drug was quantified by thin layer scanning. RESULTS: The negative control under the identification item had no interference, and the method was highly specific; in the content determination, the emodin ranged linearly from 0 2 28 μg to 1 14 0 μg (γ =0 9993), and the recovery rate was 10 0 9 . %, RSD is 2966%. Conclusion : This quality standard can effectively control the quality of Qingchang Mixture.
