Fatty acid composition of Beroe ovata (Bosc, 1802)

Fatty acid composition of Beroe ovata (Bosc, 1802)

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.
