以葛根中葛根素,麻黄中麻黄碱,甘草中甘草酸作为定性鉴别的依据成分,研究了葛根汤的薄层色谱行为,考察了展开系统、薄层板厚度、展开温度、检测方法和样品的分离纯化方法等对制剂薄层色谱的影响情况,建立了葛根汤的薄层色谱鉴别方法,本法操作简便,专属性高,重现性好。 The puerarin, puerarin and licorice glycyrrhizic acid were used as the basis for qualitative identification. The thin-layer chromatographic behavior of Puerariae was studied. The effects of spreading system, the thickness of plate, the temperature, the detection method and the sample Separation and purification methods on the thin layer chromatography, the establishment of the Pueraria TLC identification method, the method is simple, high specificity, good reproducibility.
