摘要
天然植物油中含有许多对人体有益的脂肪酸。将大豆油在水浴60℃下经甲酯化处理,并用总离子流色谱峰的峰面积进行归一化定量分析其脂肪酸成分,鉴定出亚油酸,油酸,棕榈酸,硬脂酸,肉豆蔻酸、亚麻酸、月桂酸等16种化合物。归一化结果表明,其中主要存在着四种含量较高的脂肪酸,分别为亚油酸(50.62％),油酸(32.45％),棕榈酸(11.12％)和硬脂酸(4.82％)。
There are many fatty acids in the natural seed oil which are beneficial to our health. The fatty acids in soybean oil were transesterified in methanol at 60 ℃. The initiator acids, now present as the corresponding methyl esters and the relative contents of FAMEs were analyzed by GC/MS. 16 fatty acids have been identified and their relative contents were determined by area normalization. The index of unsaturation for the oil is above 83% , oileic aicd, linoleic acid, palimitic acid and octadecenoic acid are chief components, and their relative contents are 50.62% , 32.45% , 11.12% and 4.82 % , respectively.
