GC-MS Analysis of Extracts from Zanthoxylum bungeanun Maxim by Supercritical Carbon Dioxide Extraction
The chemical constituents of supercritical carbon dioxide extraction products from Zanthoxylum bungeanun Maxim were studied by GC-MS-DS. Forty-six compounds were identified. The results showed that the main components of the extracts with higher content were 9,7-octadecadienal(21.25%), 2,5,bis (1,1-dimethylethyl)thi-ophene(14.25% ), hexadecanoic (15.00%), linalool(6. 31 % ) , oleic acid (4.52%), caryophyllene oxide(4.35%), hexadecanolide(3.53% ) , linoleic acid methyl ester(2.65% ), 1-limonene(2.25% )and so on.
