摘要

目的: 利用HPLC测定荆芥饮片煎煮过程中胡薄荷酮的含量变化

为规范含荆芥复方汤剂的临床煎煮方法提供理论依据。方法: 以胡薄荷酮为考察指标

采用高效液相色谱法在给定的色谱条件下测定荆芥饮片煎煮5

45 min后水煎液中胡薄荷酮的含量。结果: 不同煎煮时间对荆芥饮片中胡薄荷酮的含量有较大影响

胡薄荷酮成分在煎煮30 min后已基本消失。结论: 应充分尊重中药传统煎煮方法的特殊要求

对于含挥发油的中药饮片应后下

且结合临床经验认为荆芥饮片的煎煮时间为5 min。

Abstract

Objective: To study the content changes of pulegone in Schizonepetae Herba under decoction process

and to provide a reference for normalizing decoction method of Schizonepetae Herba. Method: With index of pulegone

HPLC was used to determine the content of pulegone in Schizonepetae Herba after decoction time of 5

30 and 45 minutes under given chromatographic condition. Result: Decoction time could significantly affect the content of pulegone in Schizonepetae Herba

and pulegone could not be detected after decoction time of 30 minutes. Conclusion: The special requirements in traditional decoction methods of herbs should be respected. Herbs containing essential oils should be added later during decoction

and in accordance with clinical experiences

decoction time for Schizonepetae Herba shall be 5 minutes.
