稀有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C1 4∶0、C1 6∶0、C1 8∶0。 4种单不饱和脂肪酸 (MUFA) ,它们是C1 4∶1、C1 6∶1、C1 8∶1、C2 0∶1。 4种多不饱和脂肪酸 (PUFA) ,它们是C1 8∶2、C2 0∶4、C2 0∶5 (EPA)、C2 2∶6 (DHA)。SFA占总脂肪酸的2 3 6 3— 2 8 97% ,MUFA占 40 73— 5 4 3 2 % ,PUFA占 9 96— 2 3 1 7% ,EPA占 0 41— 1 74% ,DHA占 0 1 1— 5 3 7%。EPA含量一般低于DHA。UFA(MUFA +PUFA) % >SFA % ,且MUFA % >PUFA % ,n 3FA/n 6FA为 0 3 3— 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
Three kinds of saturated fatty acids (SFA) were detected in the Han population of Rare Hyriopsis cuniculi and Pengzhou population. They were C1 4:0, C1 6:0, C1 8:0. Four monounsaturated fatty acids (MUFA), which are C1 4: 1, C1 6: 1, C1 8: 1, C2 0: 1. Four polyunsaturated fatty acids (PUFA), which are C1 8: 2, C2 0: 4, C2 0: 5 (EPA), C2 2: 6 (DHA). SFA accounted for 23.6% to 32.77% of total fatty acids, MUFA accounted for 40 73-543 32%, PUFAs accounted for 96- 231%, EPA accounted for 41-174%, DHA accounted for 0 1 1- 5 3 7%. EPA content is generally lower than DHA. UFA (MUFA + PUFA)%> SFA%, and MUFA%> PUFA%, n 3FA / n 6FA is 0 3 3- 0 99. In addition, the fatty acid composition and content of fish muscle, visceral fat, liver, gonads and the like were also determined
