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。

Abstract:Objective:To study the changes of active components in the root of Pueraria lobata after processing.Method:Using HPLC,with a C₁₈column,MeOH-H₂-O-CHCl₃(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.
