两种方法提取羌活挥发油化学成分的比较

Comparison of Two Methods for Chemical Constituents of the Essential Oil from Notopterygium incisum

目的:比较水蒸气蒸馏法(SD)和超临界CO2萃取法(SFE-CO2)所提取羌活挥发油的化学成分及其含量。方法:采用气相色谱-质谱联用技术(GC-MS)进行分析。结果:两种方法所得挥发油在成分和含量上均存在一定差异。结论:SFE-CO2法提取效率高,提取成分比较完全,为提取羌活挥发油的理想方法。

Objective：To compare the chemical components and their contents of essential oil extracted from Notopterygium incisum by the methods of supercritical CO2 fluid extraction（ SFE - CO2 ） and Steam Distillation. Methods ：The combination of gas chromatography and mass spectrometry was applied to analyze the chemical components and their contents of essential oil extracted from Notopterygium incisum. Results：The chemical components and their contents of essential oil extracted by the above two methods were different. Conclusion：SFE -CO2 is superior to SD in rasing yield and shortening extractive time. It is a good method for the extraction of essential oils from Notopterygium incisum.
