FATTY ACID COMPOSITION OF GOBIOCYPRIS RARUS

摘要: 稀有鮈鲫汉源种群和彭州种群全鱼中共检测到3种饱和脂肪酸(SFA),它们是C14∶0、C16∶0、C18∶0.4种单不饱和脂肪酸(MUFA),它们是C14∶1、C16∶1、C18∶1、C20∶1.4种多不饱和脂肪酸(PUFA),它们是C18∶2、C20∶4、C20∶(EPA)、C22∶6(DHA).SFA 占总脂肪酸的23.63-28.97%,MUFA 占40.73-4.32%,PUFA 占9.96-23.17%,EPA占0.41-1.74%,DHA占0.11-.37%.EPA 含量一般低于 DHA.UFA(MUFA+PUFA)%>SFA%,且 MUFA%>PUFA%,n-3FA/n-6FA为0.33-0.99.此外还测定了鱼肌、内脏脂肪、肝脏、性腺等的脂肪酸组成和含量.

Abstract: The fatty acid composition of whole body, muscle, liver, viscus fat and gonad in G. rarus were being studied. Saturated, Monounsaturated, In whole body polyunsaturated fatty acids represented 23.63%-28.97%,40.73%-54.32%,9.96%-23.17% of the total fatty acids in whole fish body oil respectively. EPA and DHA represented 0.41%-1.74% and 0.11%-5.37%,ω-3FA/ω-6FA were 0.33-0.99.
