Abstract

Beroe ovata was collected from Kumkapı, İstanbul, Sea of Marmara. Fatty acids composition of Beroe ovata were determined using GC/MS. Total lipid amount was found as 0.98±0.05 mg/g (n=6). Total saturated; monounsaturated and polyunsaturated fatty acids percentages were 35.78, 14.11 and 37.09, respectively. Eicosapentaenoic acid (EPA, 20:5n-3) percentage was 9.75 and docosahexaenoic acid (DHA, 22:6n-3) percentage was 23.01. Docosapentaenoic acid was not detected in Beroe ovata. EPA/DHA ratio was found as 0.42. The difference of fatty acids between the Beroe ovata with Beroe cucumis and Beroe forskalii were detection of 21:0 ve 17:1n-7 in only Beroe ovata This paper is the first study on the fatty acid composition of Beroe ovata.
