Abstract

Total lipids were extracted from 22 species of Malaysian fish and the constituent fatty acids were analysed by gas chromatography. Malaysian fish generally contained high levels of saturated fatty acids (range 36-55% total fatty acids) and contained variable amounts of monounsaturates, chiefly palmitic and stearic acids, but only trace levels of 20:1 and 22:1. Unlike fish caught in colder northern hemisphere waters, Malaysian fish were found to contain arachidonic acid (20:4 omega 6, range 2-12%) in addition to the expected eicosapentaenoic acid (20:5 omega 3, range 1-13%) and docosahexaenoic acid (22:6 omega 3, range 6.6-40.4%).

摘要

从22种马来西亚鱼类中提取了总脂质，并通过气相色谱法分析了其组成脂肪酸。马来西亚鱼类通常含有高水平的饱和脂肪酸（占总脂肪酸的36 - 55%），且含有不同量的单不饱和脂肪酸，主要是棕榈酸和硬脂酸，但仅含有痕量的20:1和22:1。与在北半球较寒冷水域捕获的鱼类不同，马来西亚鱼类除了含有预期的二十碳五烯酸（20:5 ω-3，占1 - 13%）和二十二碳六烯酸（22:6 ω-3，占6.6 - 40.4%）外，还含有花生四烯酸（20:4 ω-6，占2 - 12%）。
