化学法提取的蚕蛹油经甲酯化后 ,采用气相色谱 /质谱 (GC/MS)技术 ,对蚕蛹油中脂肪酸的组分进行了分析 ,以十九烷酸 (19∶0 )甲酯作内标物 ,气相色谱法 (GC)对蚕蛹油中α -亚麻酸进行了定量测定。结果表明蚕蛹油中α -亚麻酸的含量高达 72 80 %。本研究为α -亚麻酸的定量测定提供了实验依据
The chemical constituents of silkworm pupae oil were methylated and analyzed by gas chromatography / mass spectrometry (GC / MS). The fatty acids in the silkworm pupae oil were analyzed by using methyl nonadecanoate (19:0) Quantitative determination of α - linolenic acid in pupa oil by gas chromatography (GC). The results showed that the content of α - linolenic acid in silkworm pupa oil was as high as 72 80%. This study provided experimental evidence for the quantitative determination of α - linolenic acid
