ABSTRACT

Sturgeons are commercially the most important fish species in the world. Marine animals such as fish provide Omega-3 fatty acid EPA and DHA, which are mostly promoted for their protective effects on our heart. In the present study, the liver, muscle and Caviar of Caspian Sea Acipenser percicus from Astara region in Mar 2017 were separately extracted for their lipid content especially omega-3 fatty acids composition using the method of Blight & Dyer. The compounds were determined by Gas Chromatography-Mass Spectrometry (GC- MS). The components detected in the liver, muscle and caviar include saturated fatty acid Palmitic acid and Myristic acid, monounsaturated fatty acid Oleic acid, polyunsaturated fatty acids DHA and EPA, two methyl esters of fatty acids including Octadecanoic acid, methyl ester and Hexadecanoic acid, methyl ester. The results show that the muscle, liver and caviar of Caspian Sea Acipenser percicus are rich sources of omega-3 fatty acids were Eicosapentaenoic acid (12.56-14.18-15.12%) and Docosahexaenoic acid (12.14-13.47-14.23%).
