| 摘 要： | 对35份不同品种的亚麻籽，用无水乙醚提取亚麻籽油，经皂化、甲酯化处理，采用气相色谱一质谱（GC—MS）联用技术对其脂肪酸含量进行测定。结果表明，亚麻籽油中的平均脂肪酸含量顺序为亚麻酸（41．62％）〉油酸（25．87％）〉亚油酸（17．18％）〉硬脂酸（6．59％）〉棕榈酸（6．46％），不饱和脂肪酸含量高达85％。

| Abstract: | Flaxseed oil from 35 different flax varieties was extracted with anhydrous aether. The ex- tracted flaxseed oil was then saponified and esterfied. The composition of fatty acids in flaxseed oil was analyzed by GC -MS. The average content of fatty acids from high to low ranked as linolenic （41.62%）, oleic acid （25.87%）, linoleic （ 17. 18% ）, stearie acid （6. 59% ）, and palmitie acid （6. 46% ） . The total content of unsaturated fatty acids was up to 85%. |
