化橘红中香豆素类成分薄层色谱指纹图谱研究

TLC fingerprints of coumarins in Exocarpium citri grandis

目的 对化橘红中香豆素类成分进行薄层色谱分析, 建立能区别不同品种化橘红药材的薄层色谱指纹图谱。方法 以佛手内酯和异欧前胡素为对照品, 建立10个样品的TLC指纹图谱。结果 不同品种化橘红的图谱存在较大的差异。结论 方法简便可靠, 重现性好, 适用于化橘红药材的质量控制与鉴定。

OBJECTIVE Coumarin compounds in Exocarpium citri grandis (ECG)were analyzed to establish the TLC fingerprint of coumarins to identify various species of ECG METHODS TLC fingerprints of ten samples were established with bergapten and isoimperator as standard materials RESULTS The fingerprints of various species of ECG had obvious differences CONCLUSIONS The method is simple and reliable with a good reproducibility It could be used to identify various species of ECG
