气相色谱-质谱法测定黑豆果籽脂肪酸含量

采用气相色谱-质谱法对黑豆果籽脂肪酸组成及含量进行研究,鉴定出其含棕榈酸、硬脂酸、油酸、亚油酸、α-亚麻酸、γ-亚麻酸、哥伦比酸、二十碳酸、二十碳一烯酸、二十碳二烯酸;主要组分油酸占14.8％,亚油酸占42.8％,α-亚麻酸占14.7％,γ-亚麻酸占13.8％,不饱和脂肪酸总量达90.4％,特别是γ-亚麻酸相对含量较高,黑豆果籽具有很高保健价值和良好开发前景。

Determine the Quantity of Fatty Acid in Black Soyabean Seed by Cas Chromatography-Mas Spectrometer

This paper deal with the composition and relative quantity of fatty acid in black soyabeam seed by Gas Chromatography-Mass Spectrometer. Appraised parlmitic acid, stearic acid, oleic acid, linoleic acid, α-linolenic acid, γ-linolenic acid Columbinic acid ,eicosanoic acid, eicosenoic acid, docosenoic acid, the percentage of oleic acid, linoleic acid,α-linolenic acid and γ-linolenic acid were as folloes respectively: 14.8%, 42.8%, 14.7%, 13.8%, unsaturated fatty acid total 90.4%,functionality composition γ-linolenic acid in a higher relative quantity, it have a high value in health care and well developing prospect.
