摘　　要：目的建立灯盏细辛的薄层色谱鉴别方法。方法采用适当的提取方法,提取后用薄层色谱法鉴别灯盏细辛中的3,5-2-O-咖啡酰奎宁酸、野黄芩苷、1,3-O-二咖啡酰奎宁酸、咖啡酸4种成分。结果供试品溶液色谱中,在与对照品溶液或对照药材溶液色谱相应的位置上,均能显示相同颜色的斑点。结论薄层色谱方法简单、重复性好、专属行强,可对灯盏细辛药材进行定性鉴别。Objective To establish a TLC identification method of Erigeron breviscapus.Methods The proper extraction method was used.After extraction,the four ingredients of 3,5-di-O-caffeoylquinic acid,scutellarin,1,3-O-dicaffeoylquinic acid and caffeic acid in Erigeron breviscapus were identified respectively by thin-layer chromatography（TLC）.Results In the chromatography of sample,the same colored speckles were appeared at the corresponding positions of the control solution or control medicinal material solution.Conclusion This method is simple with strong specificity and good reproducibility,which can be used for the identification of medicinal material Erigeron breviscapus.
