摘　　要：取卵形鲳鲹白色肌肉、红色肌肉、肝脏和脾脏,用气相色谱-质谱(GC-MS)联用分析仪分析各组织器官脂肪酸组成。结果共鉴定出23种主要脂肪酸,同组织雌雄间总脂及脂肪酸组成无明显差异,不同组织间差异明显;肝脏中总脂含量最高,白色肌肉中总脂含量最低;脾脏、白色肌肉中含有丰富的高度不饱和脂肪酸,有较高的食用价值,而肝脏中含有高比例的饱和脂肪酸和单不饱和脂肪酸,多不饱和脂肪酸含量较低,是鱼体内重要的储能器官。White muscle, red muscle, liver and spleen of male and female Trachinotus ovatus were analyzed for their fatty acid composition by gas chromatography mass spectrometer （GC-MS）. A total of 23 fatty acids were identified. No significant differences were found in total lipid content or fatty acid composition of the same tissues between male and female fish. Among 4 tissues, the highest and lowest total lipid contents were found in liver and white muscle, respectively. Trachinotus ovatus spleen and white muscle were rich in polyunsaturated fatty acids （PUFA） and exhibited a high nutritional value. The contents of saturated fatty acids （SFA） and monounsaturated fatty acids （MUFA） were higher in liver with the lowest PUFA content than in other 3 tissues. Therefore, liver is an important energy storage organ in Trachinotus ovatus.
