摘要

The lipids and fatty acids of the neon flying squid (Ommastrephes bartramii) were an-alyzed to clarify its lipid physiology and health benefit as marine food. Triacylglycerols were the only major component in the digestive gland (liver). In all other organs (mantle, arm, integument, and ovary), sterols and phospholipids were the major components with noticeable levels of ceramide aminoethyl phosphonate and sphingomyelin. The significant levels of sphingolipids suggest the O. bartramii lipids is a useful source for cosmetics. Although the lipid content between the liver and all other tissues markedly differed from each other, the same nine dominant fatty acids in the triacylglycerols were found in all organs; 14:0, 16:0, 18:0, 18:1n-9, 20:1n-9, 20:1n-11, 22:1n-11, 20:5n-3 (icosapentaenoic acid, EPA), and 22:6n-3 (docosahexaenoic acid, DHA). Unusually high 20:1n-11 levels in the O. bartramii triacylglycerols were probably characteristic for western Pacific animal depot lipids, compared with non-detectable levels of 20:1n-11 reported in other marine animals. O. bartramii concurrently has high levels of DHA in their triacylglycerols. The major fatty acids in the phospholipids were 16:0,18:0, 20:1n-9, EPA, and DHA without 20:1n-11. Markedly high levels of both EPA and DHA were observed in phosphatidylethanolamine, while only DHA was found as the major one in phosphatidylcholine. In particular, high levels of DHA were found both in its depot triacylglycerols and tissue phospholipids in all organs of O. bartramii, similar to that in highly migratory fishes. The high DHA levels in all its organs suggest that O. bartramii lipids is a healthy marine source for DHA supplements.
