摘　　要：[目的]分析罗非鱼下脚料油化学成分。[方法]用气相色谱法(GC)对成分进行分析,用面积归一化法计算各组分的相对质量分数。[结果]鉴定出22中脂肪酸成分,主要成分为油酸(22.1%)、二十四碳一烯酸(20.8%)、棕榈酸(14.2%)和二十二碳一烯酸(10.1%)。[结论]单不饱和脂肪酸是罗非鱼下脚料油的主要成分,该研究为进一步开发罗非鱼可再生资源提供了科学依据。[Objective]The aim was to analyze the chemical constituents from tilapia oil.[Method]GC method was used to analyze the chemical constituents and the area normalization method was used to calculate the relative mass fraction of each chemical constituent.[Result]Twenty-two fatty acids were isolated from the tilapia oil,the predominant ones of which were oleic acid（22.1%）,nervonic acid（20.8%）,plamitic acid（14.2%）and erucic acid（10.1%）.[Conclusion]The main chemical constituent of tilapia oil was monounsaturated fatty acid.This study would provide scientific evidence for the further development of tilapia renewable resources.
