闽南近海尖头斜齿鲨 Scoliodon sorrakowah肝油的脂肪酸组成中,主要的饱和脂肪酸包括C14:0,C16:0,C18:0;单不饱和脂肪酸包括C16:1,C18:1ω9,C18:1ω7,C20:1;多不饱和脂肪酸包括C20:4ω6,C20:5ω3,C22:5ω3和C22:6ω3。尖头斜齿鲨肝油总饱和脂肪酸和总单不饱和脂肪酸含量在6月份降至最低值,8—9月升至最高值。总饱和脂肪酸的季节变化规律主要由C16:0决定,总单不饱和脂肪酸的变化主要由C16:1和C18:1ω9决定。总多不饱和脂肪酸含量在6月份达到最高值,8—9月降到最低值,11月份又上升至一定水平,这种变化主要由C22:6ω3决定。
Among the fatty acid composition of Scoliodon sorrakowah liver oil, the main saturated fatty acids include C14: 0, C16: 0, C18: 0; the monounsaturated fatty acids include C16: 1, C18: 1ω9, C18: 1ω7, C20 : 1; Polyunsaturated fatty acids include C20: 4ω6, C20: 5ω3, C22: 5ω3 and C22: 6ω3. The content of total saturated fatty acids and total monounsaturated fatty acids of pointed beaked shark liver oil decreased to a minimum value in June and rose to the highest value from August to September. The seasonal variation of total saturated fatty acids is mainly determined by C16: 0. The changes of total monounsaturated fatty acids are mainly determined by C16: 1 and C18: 1ω9. Total polyunsaturated fatty acid content in June reached its highest value, from August to September fell to a minimum, and in November rose to a certain level, this change is mainly determined by the C22: 6ω3.
