摘要
用超临界CO2 萃取技术提取重庆江津产青花椒挥发油 ,研究了萃取温度的影响 ,用色谱 -质谱联用仪分析了花椒挥发油化学成分及百分含量 ,共鉴定出 38个化合物 ,占挥发油总量的 98.81% ,其中花椒挥发油的特征有效成分之———哩哪醇含量高达 5 8.79% ,表明用超临界CO2 萃取技术提取重庆江津产青花椒挥发油品质较高。
We extracted the volatile oil of Zanthoxylum bungeanu m Maxim f rom Jiangjin, Chongqing,by supercritical CO 2 extraction technology. Effect of extraction temperature was studied. The chemical components of volatile oil of Z anthoxylum bungeanum Maxim were determined qualitatively and quantitatively by g as chromatograph-mass spectrometry-computer. 38 components separated from the extraction have been identified, accounting for 98.81% of the total of the volat ile oil. The contents of linalool, one of the most important components in the v olatile oil of Zanthoxylum bungeanum Maxim, was as high as 58.79%,which shows th at the volatile oil of Zanthoxylum bungeanum Maxim from Jiangjin, Chongqing,extr acted by supercritical CO 2 extraction technology has a high quality.
