摘要
用乙醚—正乙烷混合溶剂提取青海湖裸鲤油脂;用氢氧化钾—甲醇酯交换法甲酯化,以毛细管气相色谱法测定脂肪酸组成,鉴定了15种主要脂肪酸,其中以棕榈酸、棕榈油酸、油酸、α-亚麻酸、二十碳五烯酸(EPA)和二十二碳六烯酸(DHA)为主.
The sample of the Gymnocypris Przewalskii Pazewalskii (Kessler) Oil was extracted with a mixed solvent of ether and n - hexane.The extracts were esterified withmethanol - potassium hydroride method. Then fatty acid esters were separated and determined by capillary gas chromatography. Fifteen kinds of fatty acids have been identified. The major components are palmitic acid,palmitolic acid,oleic acid.linolenic acid,eicosapentaenoic acid and docosahexenoic acid.
