超临界CO_2流体萃取法提取艾叶与五月艾挥发油成分的研究

Study on the Chemical Constituents of Volatile Oil from Artemisia Indica and Artemisia Argyi by Supercritical CO_2 Fluid Extraction

[目的]分析广西产五月艾挥发油的主要化学成分,并与艾叶挥发油成分进行对比研究。[方法]采用超临界CO2流体萃取法分别提取艾叶和广西产五月艾中的挥发油,并通过GC-MS技术对艾叶和五月艾的挥发油成分进行分析。[结果]艾叶和广西产五月艾挥发油的得率分别为1.05%1、.32%,挥发油中均含有桉油精、龙脑、大根香叶烯D、石竹烯及其氧化物等特征成分,但挥发油的组分与含量有一定差别。[结论]以上结果可为合理使用广西产五月艾药材提供一定的科学依据。

[Objective] To analyze the chemical constituents of volatile oil in Artemisia indica produced in Guangxi and Artemisia argyi and make a comparison study between them. [Methods] The volatile oil was extracted from Artemisia indica and Artemisia argyi respectively by Supercritical CO2 Fluid Extraction. The components of volatilde oil were separate and analyzed by GC - MS. [Resuits] The yield rate of the collected volatile oil from Artemisia indica produced in Guangxi and Artemisia argyi was 1.05 % and 1. 32% respectively and both the volatile oils from Artemisia indica and Artemisia argyi included Eucalyptol, Bomeol, Germacrene D, Caryophyllene, Caryophllene oxide, etc. which were the characteristic components in volatile oil. But there was some difference in the component and content in volatile oil from Artemisia indica and Arternisia argyi. [Conclusions] Above results can provide some scientific basis for rational use of Arternisia argyi produced in Guangxi.
