超临界CO_2和有机溶剂提取艾蒿叶中风味物质的研究

Study on extracting flavor effective component of artemisia argyi with solvent extraction and supercritical fluid extraction

采用有机溶剂提取法和超临界CO2 流体萃取法分别提取艾蒿叶风味物质 ,并用气相———质谱联用仪检测了提取的风味物质的化学成份。结果表明 ,采用不同方法得到的提取物的化学成分有所不同 ,超临界CO2 萃取物的化学成份较少 ,艾蒿叶精油纯度高 ,是提取艾蒿叶风味物质较优的工艺方法。

In this paper ,we extract the effective compoents of Artemisia argyi with solvent extraction and supercritical fluid extraction (SFE) .The components has been measured with GC-MS. The components of supercritical fluid extract are more pure ,it is a effective extraction technology.
