| 目的：控制产品质量。方法：采用 薄层色谱（TLC）法鉴别制剂中赤芍、山银花、黄柏、防风；采用高效液相色谱（HPLC）法测定制剂中苦参碱的含量。结果：TLC 斑点清晰，分离度好，阴性无干扰。含量测定苦参碱在 0.137501~4.400046 μg 间线性关系良好，线性方程Y= 2.0270×106 A - 2843.7361，r = 0.9999，平均回收率为 100.07%（RSD =2.2%，n=6）。结论：该质量标准项目设置合理，操作便捷、准确，可用于对银屑灵颗粒的质量控制。 |

| Objective: Establish the quality control method of Yinxieling granules. Methods:Radix Paeoniae Rubra, Flos Lonicerae,Cortex Phellodendri and Radix sileris were identified by TLC, and the contents of matrine in the preparation were deter mined by HPLC.Results:TLC spots were clear, good separation and negative.The content deter mination method of matrine showed a good linear relationship between 0.275003 ~ 4.400046 μg. The average recovery of matrine in Yinling granules was 100.07%,(RSD 2.2%,n=6).Conclusion:The method is simple, accurate and effective in separation, and can be used to evaluate the quality of Yinling granules. |
