不同品种亚麻籽脂肪酸含量的 GC -MS 分析 . Analysis of Fatty Acids of Flaxseed with GC-MS

Abstract

Flaxseed oil from 35 different flax varieties was extracted with anhydrous aether. The extracted 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%),stearic acid( 6. 59%),and palmitic acid( 6. 46%). The total content of unsaturated fatty acids was up to 85%.
