采用气相色谱-质谱法(GC-MS)和气相色谱法(GC)分析木薯蚕蛹油中脂肪酸的组分及含量。通过GC-MS定性测定,木薯蚕蛹油中含有11种脂肪酸,通过面积归一法分析。各脂肪酸含量为α-亚麻酸43.41%,棕榈酸21.15%,油酸11.59%,亚油酸10.28%,硬脂酸8.08%,棕榈油酸1.88%,豆蔻酸0.93%,十五碳酸0.31%,反式6-油酸0.24%,月桂酸0.16%和9,10-甲基十九烷酸0.16%;通过GC定量测定,木薯蚕蛹油含α-亚麻酸57.63%,棕榈酸20.62%,油酸7.68%,亚油酸6.28%和硬脂酸3.38%。木薯蚕蛹中含有丰富的不饱和脂肪酸,特别是较多的α-亚麻酸。

To analyze of fatty acid compositions in eri silkworm pupa oil and to provide scientific basics in the comprehensive utilization of eri silkworm pupa.Method: Crude lipids were extracted by organic solvent,then gas chromatography-mass spectrogrophy(GC-MS) and gas chromatography(GC) were used in the analysis of fatty acid.Result: The lipid of eri silkworm pupa is relative less(19.16%).The fatty acid compositions are C18∶3(43.41%),C16∶0(21.15%),C18∶1(11.59%),C18∶2(10.28%),C18∶0(8.08%),C16∶1(1.88%),C14∶0(0.93%),C15∶0(0.31%),C12∶0(0.16%)and cyclopropaneoctanonic acid(0.16%).The most abundant fatty acid is C18∶3(57.63%),and C16∶0(20.62%),C18∶1(7.68%),C18∶2(6.28%) and C18∶0(3.38%) are less.
