| 摘 要： | 采用碱液浸泡法从蚕蛹中提取总脂肪，经甲酯化后,采用GC/MS法分析其脂肪酸的组成及相对百分含量，并用核磁共振 1H NMR法鉴别其脂肪酸的酯型。蚕蛹油中含有15种脂肪酸,其中不饱和脂肪酸占71.20%,亚麻酸的相对百分含量高达32.06%，其存在形式主要是脂肪酸甘油酯。

| Abstract: | Silkwormpupa oil was extracted by alkali liquor. Fatty acid in silkwormpupa oil was modified by methyl esters.The compositions and type of fatty acids were determined by GC/MS and NMR. 15 compositions in silkwormpupa oil are characterized and determined.The relative content of unsaturated fatty acids is 71.20%.Linolenic acid is nearly 32.06%. Existing forms are mainly fatty acids glycerin ester. |
