摘要
目的：研究葛根炮制前后有效成分的变化。方法：采用ＨＰＬＣ法，Ｃ１８柱，流动相为甲醇水氯仿（２５∶７５∶１），检测波长为２５０ｎｍ。结果：除炒炭对葛根素破坏严重外，其他炮制品中葛根素的含量均比生品高。结论：炮制对葛根中葛根素含量影响较大。
Objective:To study the changes of active components in the root of Pueraria lobata after processing.Method:Using HPLC,with a C 18 column,MeOH H 2O CHCl 3(25∶75∶1) as mobile phase,and flow rate 1ml/min.Result:The Puerarin in different processed products of the drug is increased in content,but gets seriously destroyed if processed by carbonizing.Conclusion:The Puerarin content in the root of Pueraria lobata is affected by drug processing.
