The obtained results indicated that the total lipid contents of the B. semiorbiculata harvested in Nam Du and Phu Quoc islands were and of wet weight respectively and contained six classes Hydrocarbon and wax HW triacylglycerol TAG free fatty acids FFA sterol ST polar lipid PoL and monoalkyl diacylglycerol MADAG . Two main classes in the total lipid content of two studied mussels were triacylglycerol TG and and polar lipid PL and . PL of both muselles consited of five types Phosphatidylethalnolamine PE phosphatidylcholine PC phosphatidylserine PS phosphatidylinositol PI and ceramide aminoethylphosphonate CAEP in which phosphatidylethanolamine PE and and phosphatidylcholine PC and were dominated. The content of polyunsaturated fatty acids in the total lipid of B. semiorbiculata collected in Phu Quoc was higher than that in Nam Du. The content of n-3 and n-6 fatty acids 20 4n-6 20 5n-3 22 6n-3 was high in the composition of fatty acids of both mussels. Keywords Lipid phospholipid fatty acid Beguina .
