摘　　要：采用冷冻干燥和改进的Bligh-Dyer方法提取脂肪酸,用GC-MS测定了斑头雁腿肌、胸肌组织和卵的脂肪酸组成情况,含有脂肪酸27种.均为长链脂肪酸(C_(14:0)以上)。其中饱和脂肪酸19种,占总含量的80.577%-87.701%;不饱和脂肪酸8种,占脂肪酸总含量的12.298%-19.423%。在斑头雁的腿肌、胸肌和卵组织中,脂肪酸组成差异不大(P<0.05)。肌肉中含有的脂肪酸种类要多于卵组织中含有的脂肪酸种类。在斑头雁组织含有10种带有甲氧基的脂肪酸,分别占腿肌脂肪酸总量的36.175%,胸肌脂肪酸的10.401%,卵脂肪酸的45.339%。The fatty acids were extracted by modified Bligh-Dyer method and freeze drying,and the components of fatty acids in the leg muscles,chest and eggs of Anser indicus were determined by GC-MS,and there were 27 kind of fatty acids,that were long chain fatty acidsCabove C_（14·0））,19 kind of saturated fatty acids were 80.577%—87.701%of total fatty acids content,then 8 kind of unsaturated fatty acids were 12.298%—19.423%of total fatty acids content.The fatty acids components in the leg muscles,chest and eggs of Anser indicus had no significant difference （P0.05）.Muscles contained the fatty acids species more than that of eggs.The 10 varieties fatty acids with oxygen radicals were obtained in organization of Anser indicu,and leg muscles contained myo-fatty acid 36.175%,while chest muscle contained myo-fatty acid 10.401%and eggs had myo-fatty acid 45.339%.
