摘　　要：分析比较了乌骨鸡与非药用鸡种鸡肉间的总脂质含量和脂肪酸组成的差异,为研究乌骨鸡总脂质的营养与补益功能提供基础。以相同条件养殖的非药用鸡种崇仁麻鸡、岭南黄鸡鸡肉为对照,测定3种鸡肉中的总脂质含量。采用GC-MS联用技术对3种鸡脂肪的脂肪酸组成进行定性、定量分析。结果发现:3种鸡肉中崇仁麻鸡的总脂质含量最高,乌骨鸡的含量最低。3种鸡的总饱和脂肪酸(SFA)和不饱和脂肪酸(UFA)差别不显著,乌骨鸡鸡肉中多不饱和脂肪酸(PUFA)、必需脂肪酸(EFA)和花生四烯酸质量分数分别为26.4%、23.38%、3.21%,显著高于其他两种鸡。乌骨鸡总脂质较非药用鸡种的总脂质有更好的营养价值。Total lipid and fatty acids composition were determined in the muscles of black-bone silky fowl, Chongren Chicken , and Lingnan yellow Chicken which were bred under the same feeding and keeping conditions. The highest total lipid content was detected in black-bone silky fowl but the lowest in Lingnan yellow Chicken. There were no significant differences in the total saturated fatty acid （SFA） and unsaturated fatty acid （UFA） among those three kinds of chickens. GC/MS analysis showed： There were no significant differences in the total saturated fatty acid （SFA） and unsaturated fatty acid （UFA） among those three different kinds of chickens. The content of polyunsaturated fatty acid （PUFA）,essential fatty acid （EFA） and Arachidonic acid （AA） in black-bone silky fowl were 26.4%,23.38% and 3.21% respectively which were significantly higher than other two chickens. The total lipid in black-bone silky fowl had higher nutritional value than that of other two chickens.
