目的:修改康儿灵颗粒中原橙皮苷薄层鉴别方法,建立其他药材的薄层鉴别方法。方法:修改橙皮苷的鉴别采用聚酰胺薄膜薄层鉴别方法,同时采用TLC法对方中枳壳、胡黄连、甘草等药材进行定性鉴别。结果:修改后的鉴别方法重现性及专属性均较原法好,并能分别检出枳壳、胡黄连、甘草,阴性对照无干扰。结论:改进的薄层色谱鉴别方法分离度、重现性好,专属性强,可用于康儿灵颗粒的定性控制。 Objective: To modify the konjac glucomannan TLC method to establish the TLC identification method of other herbs. Methods: The identification of hesperidin was modified by thin layer of polyamide film identification method, while the TLC method of the other side Fructus, Picrorhiza, licorice and other herbs qualitative identification. Results: Reproducibility and specificity of the modified identification method were better than the original method, and were able to detect Fructus Aurantii, Coptis, licorice, and negative control without interference. Conclusion: The improved thin-layer chromatography identification method has good resolution, reproducibility and specificity and can be used for the qualitative control of Kang Er Ling particles.
