| Abstract: | 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. |
