Fatty acids in female’s gonads of the Red Sea fish Rhabdosargus sarba during the spawning season

Journal of Coastal Life Medicine 2014年第5期 411-415页

作者： Suhaila Qari Samia Moharram Safaa Alowaidi Department of Biological Sciences University of King AbdulazizJeddah CitySaudi Arabia

Objective:To determine the fatty acids profiles in female fish,Rhabdosargus sarba(***)from the Red Sea during the spawning ***:Monthly individual *** were obtained from Bangalah market in Jeddah,Red Sea and transported to the laboratory in ice *** total length,standard length and weight were measured,fishes were *** were removed,weighed and 10 mL of concentrated hydrochloric acid were added to 10 g of the ovary in a conical flask and immersed in boiling water until the sample was dissolved and the fat was seen to collect on the *** conical was cooled and the fat was extracted by shaking with 30 mL of diethyl *** extract was bowled after allowing the layers to separate into a weighed *** extraction was repeated three times more and distilled off the solvent then the fat dried at 100℃,cooled and *** 50 mg of lipid was put in a tube,5 mL of methanolic sulphuric acid was added and 2 mL of benzene,the tube well closed and placed in water bath at 90℃for an hour and a *** cooling,8 mL water and 5 mL petroleum were added and shaked strongly and the ethereal layer was separated in a dry tube,evaporated to *** fatty acid methyl esters were analyzed by using a Hewlett Packard(HP 6890)chromatography,a split/splitless injector and flame ionization ***:In female ***,a total of 29 fatty acids were detected in ovaries throughout the spawning *** main fatty acid group in total lipid was saturated fatty acid(SFA,28.9%),followed by 23.5%of polyunsaturated fatty acids(PUFA)and 12.9%of monounsaturated fatty acids(MUFA).The dominant SFA were palmitic and stearic,the major MUFA were palmitoleic and oleic,and the major PUFA were C18:2 and C22:*** spawning stages,there were no significant differences in total SFA,MUFA and *** highest value of SFA was in late spawning(36.78%).However,the highest value of MUFA and PUFA was in spawning(16.70%and 24.96%respectively).During spa
