目的从石油醚提取成分的角度探讨豨莶草生品和炮制品成分的变化,为豨莶草炮制前后功效差异提供内在成分变化的依据。方法采用GC/MS联用法,对豨莶草炮制前后石油醚提取成分加以比较分析。结果豨莶草经炮制后出现了11种新的石油醚提取成分。结论豨莶草炮制前后石油醚提取成分发生了很大变化。
Objective To explore the changes of raw components of barnyardgrass and processed products from the perspective of petroleum ether extraction components, and to provide basis for the changes of the internal components before and after the effects of prunella. Methods The GC/MS combination method was used to compare and analyze the components of petroleum ether before and after processing. Results 11 kinds of new petroleum ether extracts appeared after processing. Conclusion The components of petroleum ether extraction before and after the processing of Echinochloa are changed greatly.
