摘　　要：采用GC分析溶剂浸提法所得苹果籽油脂肪酸组成,结果表明苹果籽油中主要含有6种脂肪酸,分别为棕榈酸、硬脂酸、油酸、亚油酸、花生一烯酸和亚麻酸,不饱和脂肪酸含量近80%;胰脂酶水解甘油三酯表明苹果籽油sn–2位脂肪酸以油酸、亚油酸为主,含量占90%以上;RP–HPLC–ELSD分析了苹果籽油的甘油三酯组成,主要包括11种甘油三酯,其中LLL、OLL、OOL占70%以上,进一步验证了苹果籽油属于油酸―亚油酸型油脂。Fatty acid composition of apple seed oil after solvent extraction was analyzed by GC. Results showed that there were 6 kinds of fatty acids in apple seed oil,including palmitic acid,stearic acid,oleic acid,linoleic aicd,eicosenoic acid and linolenic acid. Of which the unsaturated fatty acids were nearly 80%. sn–2 FFA composition was analyzed by hydrolysis of apple seed oil with porcine pancreatic lipase,results indicated that the main FFA were oleic acid and linoleic acid,which account for more than 90%.The TAG composition was determined with 11 kinds of TAGs determined by RP–HPLC–ELSD,the content of LLL、OLL、OOL account for more than 70%. Thereby apple seed oil was further certified as the oleic–linoleic group oil.
