摘要
通过气相色谱-质谱联用(GC-MS)测定荞麦籽油中的脂肪酸含量,用外标法与峰面积归一法进行定量分析。荞麦籽油脂肪酸种类丰富,以不饱和脂肪酸为主,其中单不饱和脂肪酸为45.10%,多不饱和脂肪酸为32.76%。荞麦籽油中4种脂肪酸含量:油酸>亚油酸>棕榈酸>硬脂酸。
This article analyzed the fatty acid in buckwheat seed oil by GC-MS,comparing external standard method and peak area normalisation method to analyze quantitatively.There are different kinds of fatty acid in buckwheat seed.The main kind is unsaturated fatty acid.The buckwheat seed had 45.10 % unsaturated fatty acid and 32.76 % polyunsaturated fatty acid.The content of the four fatty acids in buckwheat seed： oleic acid 〉linoleic acid〉palmitic acid〉stearic acid.
