Analysis of Fatty Acid Composition in Milt of Oncorhynchus keta by Gas Chromatography-Mass Spectrometry

Abstract

Gaschromatography-mass spectrometry (GC-MS) was applied to the analysis of fatty acid composition in milt of chum salmon Oncorhynchus keta. Arachidonic acid and eicosapentaenoic acid (which were precursors of prostaglandin G₂ and G₃ respectively) were identified. Myristic acid, palmitic acid, arachidic acid, oleic acid, linolenic acid and docosahexaenoic acid were also identified.
