Comparison of fatty acids composition between diploid and triploid Japanese scallop,Patinopecten yessoensis

By means of capillary gas chromatography column,fatty acids composition in diploid and trploid Japanese scallop (Patinopecten yessoensis) was studied.The main results were as follows:①The composition of fatty acids in muscle and mantle was similar to both scallops.They were all PUFASFAMUFA and n 3PUFAn 6PUFA.The main fatty acids were 22∶6n 3(23.9%-28.9%),20∶5n 3(17.6%-20.6%),16∶0(11.0%-19.4%),18∶0(7.3%-8.1%) and 20∶4n 6(2.8%-5.5%);②Diploid and triploid scallop had similar kinds of fatty acids in gonad,but there were significant differences in the contents of fatty acids between the two scallops,in which triploid scallop had significantly higher levels of SFA and MUFA,but lower level of PUFA in gonad than those of diploid scallop(P0.01).
