摘要
目的:研究不同产地青蒿种子的脂肪酸含量。方法:以二氯甲烷为抽提剂,利用索氏提取法提取青蒿种子中的脂肪酸,经甲酯化处理后,采用气相色谱-质谱(GC-MS)联用技术对青蒿种子的脂肪酸成分进行分析和鉴定。结果:从酉阳及黑龙江青蒿种子中分别鉴定出10个和11个脂肪酸类化合物,占挥发性成分总量的97.59%和96.06%。棕榈酸(6.67%,11.82%)、亚油酸(81.99%,73.61%)及硬脂酸(3.31%,3.31%)为2个产地青蒿种子的主要脂肪酸。结论:2种青蒿种子的脂肪酸组成大致相同,但各脂肪酸的含量差异明显。
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 an- alyzed 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.
