The component fatty acids of the muscle, liver, and viscera lipids from the squid, Illex illecebrosus (Le Sueur), caught in Newfoundland waters have been determined by gas–liquid chromatography (GLC). Silicic acid chromatography was used to segregate the main groups of lipids and the fatty acid composition of each fraction was determined on two organosilicone polyester columns.The lipids from the muscle consisted mainly of phospholipids with three fatty acids, palmitic (16:0), eicosapentaenoic (20:5), and docosahexaneoic (22:6) acids making up 80% of the total. The liver contained mainly triglycerides with a fatty acid composition similar to liver oils in other marine species.
