Abstract：In this study,Abalone Visceral Phospholipids(AVP)was used as the research object to study its hypolipidemic effect on high-fat diet mice.The components,fatty acid composition and physicochemical properties of AVP were analyzed.The results showed that AVP was composed of phosphatidylcholine,phosphatidylethanolamine and phosphatidylinositol,with their contents being 80.69%,3.66%and 5.06%,respectively.There were five saturated fatty acids and nine unsaturated fatty acids(content:15.97%).AVP was brownish-yellow particles with a phospholipid smell,acetone-insoluble matter cntent as 88.3%,content of water and volatiles as 0.8%,n-hexane insoluble matter content as 0.1%,acid value as 34.4 mg KOH/g,and peroxide value as 9.45 mmol/kg,all of which met the national standards.Animal experiments were carried out to verify the auxiliary hypolipidemic effect of AVP on mice fed a high-fat diet.The results showed that compared with the high-fat diet group,the serum TG,TC,and LDL levels in the high-dose AVP group decreased by 47.63%,32.02%,and 44.73%,respectively,the serum HDL increased by 30.78%,and the AI index decreased by 64.85%.In summary,AVP plays a certain role in assisting the reduction of hyperlipidemia,which provides a theoretical basis for the subsequent development and utilization of abalone viscera resources.
