摘要 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% ) , C15:0(21.15% ), C18: I(11.59% ), C18:2(I0.28% ), C18:0(8.08% ), C15:1 (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.
