目的建立银翘柴黄颗粒质量控制方法。方法采用薄层色谱法鉴别银翘柴黄颗粒中金银花、柴胡、黄芩及甘草,HPLC测定连翘酯苷A的含量。结果在选定的色谱条件下,薄层色谱斑点清晰、分离度好,阴性对照未见干扰。含量测定连翘酯苷A在0.029 6~0.474μg范围内线性关系良好,平均回收率为99.73%,RSD=1.18%。结论本方法准确、简便,能够有效控制银翘柴黄颗粒的质量。
Objective To establish the quality control method of Yinqiao Chaihuang granules. Methods The TLC, Flos Lonicerae, Radix Scutellariae and Radix Glycyrrhizae were determined by TLC. The content of Forsythiaside A was determined by HPLC. Results Under the selected chromatographic conditions, the TLC spots were clear and the resolution was good. No interference was observed in the negative control. Determination of Forsythiaside A in the range of 0.029 6 ~ 0.474μg good linearity, the average recovery was 99.73%, RSD = 1.18%. Conclusion This method is accurate and simple, and can effectively control the quality of Yinqiao Chaihuang granules.
