Fatty acid compositions in Thai marine sponges (Order Hadromerida)

Abstract

Seven specimens of marine sponges (Order Hadromerida; Families Spirastrellidae, Tethyidae, and Clionaidae) were analyzed for their fatty acid compositions. The predominant

compositions were 16:0, 20:5n3 and 22:6n3. Most of them were saturated (22.53-36.41%) and

polyunsaturated (19.38-55.54%) fatty acids. The essential fatty acids, eicosapentaenoic acid or

EPA (20:5n3) and docosahexaenoic acid or DHA (22:6n3), were found with the highest

concentrations, KODA-13; 11.85±0.35% and LSNG-07; 24.36±0.52%, in non-polar lipid of Spira strella sp. and Spirastrella solida, respectively.
