摘要 目的:建立北沙参的薄层色谱指纹图谱,用于对北沙参药材进行真伪鉴别及质量控制。方法:以法卡林二醇、东莨菪素、伞形花内酯、异欧前胡素为对照品,采用薄层色谱法对10批不同采集地的北沙参商品药材及3批山东莱阳北沙参药材进行定性鉴别。采用双波长扫描法,以260 nm为参比波长,300 nm为检测波长,荧光模式进行扫描,得出北沙参的薄层扫描轮廓图。结果:由轮廓扫描图发现13批北沙参药材有8个主要峰,其中4个为法卡林二醇、东莨菪素、伞形花内酯、异欧前胡素,并且山东莱阳产北沙参中4个化合物的含量均高于其他10批商品药材。结论:该方法稳定、简便可行,可用于北沙参的真伪鉴别及质量控制。 Objective: To establish TLC fingerprint of Glehniae Radix for the identification and quality control of the drug.Methods:10 batches of Glehniae Radix commercial drugs collected from different gathering areas and 3 batches from Laiyang,Shandong were used as qualitative identification samples.Falcarindiol、scopoletin、umbelliferone and isoimperatorin were used as the chemical reference substances.Double wavelength TLCS was performed with petroleum and ethyl acetate(4∶1) as developer,detection wavelength at 300 nm and reference wavelength at 260 nm.Results:TLC chromatogram of 13 samples had 8 well-resolved characteristic peaks,in which 4 peaks were falcarindiol,umbelliferone,scopoletin and isoimperatorin,respectively.Conclusion: The method is accurate and simple,and can be used for the quality control of Glehniae Radix.
