Abstract

Objective:To explore the fatty acids of the different regions A.annua seeds.Methods:The fatty acids were given by Soxhlet extraction from two A.annua seeds.The chemical compositions of extracts were analyzed by GC-MS technique.Results:Eeleven and twenteen fatty acids were identified from the A.annua seed from Youyang of Chongqing and Harbin of Heilongjiang,representing 97.59% and 96.06% of total Volatile components,respectively.Among of them,palmitic acid(6.67%,11.82%),linoleic acid(81.99%,73.61%),stearic acid(3.31%,3.31%) were major compounds of the two A.annua seed.Conclusions:The A.annua seed collected from Harbin City of Heilongjiang and Youyang of Chongqing in China,their fatty acids constituents were roughly the same,but the content of each fatty acid were significant differences.
