| 摘 要： | 本文研究了番木瓜种子的提取方法及超声提取条件。试验表明超声提取法是一种提取时间短、溶剂用量少、出油率高的提取方法。采用L9(34)正交试验法找到其最佳提取条件:提取次数3次,料液比1∶10,超声时间20 m in。本文还探讨了适合番木瓜脂肪酸成分鉴定的甲酯化方法;并运用气-质联用鉴定出番木瓜中自由中脂肪酸的种类及含量为:棕榈酸(17.34%)、硬脂酸(5.22%)、二十碳烷酸(1.12%)、油酸(69.25%)、亚油酸(4.31%)、十九碳烯酸(1.68%)、二十碳烯酸(0.75%)、二十一碳烯酸(0.33%)。

| 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%), C17 H35COOH (5.22%), C19H39COOH (1.12%), C17H33COOH (69.25%), C17H31COOH (4.31%), C18H35COOH (1.68%), C19H37 COOH (0.75%), C20H39COOH (0.33%). The content of unsatisfied fatty acid was 75.92%. |
