Abstract: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%, cluding eight fatty acids and three long-chain alkanes, the main 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.
