番木瓜种子油提取方法及成分的研究-柷红(GC-MS) . Study on the Extraction Method and Constituents of Papaw Seed Oil

Abstract

The extraction method and the condition of supersonic extraction to papaw seed were studied.The result showed that supersonic extraction was a good method with less time and high extraction rate.And the orthogonal experiment proved that the best condition was that the papaw seed was extracted 3 time;the proportion of dissolvent and the seed was 1∶10,and the time for once was 20 min.The methyl esterification method and the condition of GC for the fatty acid of oil and its content: C15H31COOH(17.3%),C17H35COOH(5.22%),C19H39COOH(1.12%),C17H33COOH(69.25%),C17H31COOH(4.31%),C18H35COOH(1.68%),C19H37COOH(0.75%),C20H39COOH(0.33%).the content of unsatisfied fatty acid was 75.92%.
