摘　　要：目的:明确还阳参与其易混淆品蒲公英的鉴别要点,正本清源,为还阳参采收加工提供依据,保证药材质量。方法:通过观察比较植物形态及药材性状总结二者差异,薄层色谱法以绿原酸为对照品对二者加以鉴别。结果:还阳参与蒲公英在茎、叶、花、种子等方面存在差异,在绿原酸对照品色谱相应的位置上,还阳参显相同颜色的荧光斑点,蒲公英不显斑点。结论:此方法准确可靠,可用于还阳参与其混淆品蒲公英的鉴别。Objective:To clarify the identification points of Dandelion,which is easy to be confused by Crepis crocea,and to provide the basis for the collection and processing of Crepis crocea,and to ensure the quality of medicinal materials.Methods:The differences were summarized by observing and comparing the plant morphology and medicinal properties of the two. Thin-layer chromatography was used to identify the two with chlorogenic acid as a reference. Results:There were differences in stems,leaves,flowers and seeds between Crepis crocea and Dandelion.In the corresponding position of chlorogenic acid control,the same color of fluorescence spots appeared in Crepis crocea,but not in Dandelion. Conclusion:The method is accurate and reliable,and can be used for the identification of Crepis crocea and its adulterant Dandelion.
