| Abstract: | The chemical components of supercritical carbon dioxide extracts from seeds of Zanthoxylum bungeanun Maxim. were studied by GC-MS-DS.Thirty-five compounds which account for 96.22% of the total area of the chromatographic peaks , were identified.The results showed that fatty acids and esters occupied 90.83%of total chromatographic efflux of the extracts.The main components of the extracts are oleic acid(38.91%),palmitic acid (29.45%),linoleic acid methyl ester(10.80%),linolenic acid methyl ester(8.64%),et al. |
