麻杏石甘散超微粉的TLC鉴别研究

TLC identification of maxingshigansuperfine powder

建立麻杏石甘散超微粉中麻黄、苦杏仁、甘草的薄层鉴别方法,并对其进行鉴别。采用薄层色谱方法(TLC),选用硅胶G板对麻杏石甘散超微粉中的麻黄、苦杏仁、甘草进行研究。建立了上述3种药物的薄层鉴别方法,在供试品色谱中,在与标准品色谱相应的位置上显相同颜色斑点,且斑点分离度较好,阴性无干扰。建立的麻黄、苦杏仁、甘草的薄层鉴别方法重现性好,操作简单,可作为麻杏石甘散超微粉的质量控制标准。

To establish methods for TLC identification of ephedra,semen armeniacae amarae,liquorice in Maxingshigan superfine powder.TLC identification method,selected the silica gel G to study ephedra,semen armeniacae amarae,liquorice in Maxingshigan superfine powder.Set up TLC identification methods of the above three kinds of drugs,in the chromatogram of the samples,in the position of accordingly with reference substance chromatography showed the same color spots,and spot has good separating degree,negative without interference.The established TLC identification methods of ephedra,semen armeniacae amarae,liquorice with good reproducibility,simple operation,can be used as Maxingshigan superfine powder quality control standards.
