摘 要:用溶剂热抽提蛇油脂肪和KOH/甲醇酯交换甲酯化,以气相色谱-质谱联用技术测定脂肪酸组成,鉴定了29种脂肪酸成分,其中含量较高的成分有肉豆蔻酸,棕榈油酸,棕榈酸,亚油酸,油酸,硬脂酸,花生四烯酸,二十碳三烯酸,二十碳二烯酸,二十二碳四烯酸等.蛇油中不饱和脂肪酸的含量占脂肪酸总量的63%以上.Snake oils were extracted with refluxing petroleum ether. The fatty acids from snake oils were esterified by KOH/CH 3OH in the existence of BF 3,and fatty acid esters were determined by GC MS. Twenty nine kinds of fatty acids were identified. The result shows that the main compositions of snake oils are myristic acid, palmitoleic acid, palmitic acid, linoleic acid, oleic acid, stearic acid, arachidonic acid etc, and the mass frictions of unsaturated fatty acids in snake oils are higher than 63% of total fatty acids.
