杨梅核脂肪酸及蜡质成分分析

Fatty Acids and Waxes in Kernel of Myrica rubra

采用GC-MS联用技术,对杨梅(Myrica rubra)核中的脂肪酸及蜡质成分进行了分析。结果表明,杨梅核中脂肪酸和蜡质的总含量为31.10%,其中含有8种脂肪酸和3种长链烷烃,主要为棕榈酸(C16:0)28.22%、亚油酸(C18:2)14.4%、顺式-油酸(C18:1)25.74%、芥酸(C22:1)15.68%、十七烷5.2%、十八烷5.87%和十九烷4.71%,是一种优质和价廉的脂肪酸来源。

The fatty acid components and waxes extracted from Myrica rubra kernel were analyzed by GC-MS. The results showed that the yield of kernel oil was 31.10%, including eight fatty acids and three long-chain alkanes, the mare components were palmitic acid （C16：0） 28.22%, linoleic acid （C18：2） 14.4%, oleic acid （Z） （C18：1） 25.74%, erucic acid （C22：1） 15.68%, heptadecane 5.2%, octadecane 5.87%, and nonadecane 4.71%. They provide an abundant and cheap resource of the fatty acid.
