摘　　要：生物油脂经超临界CO2萃取提纯,再经甲酯化处理后,用气相色谱质谱联用分离技术对其各组份进行定性分析.实验结果表明:该方法对样品分离效果良好.所测样品主要成分及含量分别为12碳烯十八酸42.70%、花生四烯酸14.92%、5甲基十七酸10.33%、8,11,14二十碳三烯酸6.31%.Faffy acid of lipid was extracted by supercritical fluid. After saponification and esterification,the faffy acid was determined by capillary GC - MS 17 componnds have been separated and identified. The main components and relative contents are 12 - octadecenoic acid 42. 70%, 5,8,11,14 - Eicosatetraenoic acid 14.92 % and heptadecanoic acid 10.33 %, 8,11,14 - eicosatrienoic acid 6.31%.
