冷水花药材的薄层指纹图谱研究

Fingerprint of Pilea aquarum Dunn by TLC

采用硅胶GF254板,分离冷水花80%乙醇提取物中石油醚和乙酸乙酯两个萃取部位的化合物,分别以石油醚-三氯甲烷-丙酮(5∶0.5∶1)、石油醚-三氯甲烷-丙酮(2∶1∶1)为展开系统,对上述两个萃取部位进行薄层色谱研究。实验得到的冷水花药材各萃取部位的薄层指纹图谱斑点清晰,能有效鉴别冷水花药材。

Silica gel GF254 plates are used in isolating the compounds in the petroleum ether and ethyl acetate extraction of 80% ethanol extract of Pilea aquarum Dunn;and the expand system of petroleum ether-chloroform-acetone（5∶0.5∶1）,petroleum ether-chloroform-acetone（2∶1∶1） are used in studying the TLC of each part.Results： The TLC distinction is fairly clear and it can distinguish effectively each part of Pilea aquarum Dunn.Conclusion： The fingerprint of Pilea aquarum Dunn by TLC has been proved to have good separation effect and it is reproducible,specific,simple and feasible.
