目的:建立康瘫丸的质量标准。方法:用薄层色谱法对康瘫丸中的黄芪、赤芍、羌活、当归进行定性鉴别;HPLC法测定制剂中芍药苷含量;检测波长230 nm,流速1.0 ml·min~(-1)。结果:薄层色谱斑点清晰,芍药苷在21.6～216.0μg·ml~(-1)浓度范围内线性关系良好(r=0.999 9),平均回收率为99.5%,RSD为1.15%(n=6)。结论:本方法简便、准确,可控制该制剂的质量。
Objective: To establish the quality standard of Kangliang Pills. Methods: The contents of paeoniflorin were determined by thin layer chromatography (HPLC). The detection wavelength was 230 nm and the flow rate was 1.0 ml · min ~ (-1). Results: The TLC spots were clear. Paeoniflorin had a good linearity (r = 0.999 9) within the range of 21.6-216.0 μg · ml -1 with an average recovery of 99.5% and a RSD of 1.15% (n = 6 ). Conclusion: This method is simple, accurate and can control the quality of the preparation.
