摘　　要：采用气相色谱法对海洋鱼油软胶囊中脂肪酸组成和比率进行分析,为合理补充DHA、EPA等多不饱和脂肪酸提供理论依据,并为鉴别海洋鱼油质量提供基础数据。结果表明：鱼油软胶囊中主要含有C14~C22脂肪酸,其中不饱和脂肪酸质量分数50.8%~85.1%,特别是具有重要生理作用的多不饱和脂肪酸,如C20：5（EPA,约占10.0%~35.1%）、C22：6（DHA,约占10.7%~20.5%）;鱼油软胶囊中n-3不饱和脂肪酸质量分数约为22.5%~55.7%,n-6不饱和脂肪酸与n-3不饱和脂肪酸的比率约为0~0.7,EPA与DHA的比率约为0.8~1.9。In this paper, in order to provide a theoretical basis for reasonable supplement DHA, EPA and other polyunsaturated fatty acids, and provide baseline data for the identification of marine fish oil quality, the constituents and ratios of fatty acid in sea fish oil soft capsules were analyzed by gas chromatography （GC）. The main results showed that： the main fatty acids in sea fish oil soft capsules were C14 - C22 and about 50.8% ~ 85.1% of fatty acids were unsaturated fatty acids, especially polyunsaturated fatty acids which had important physiological function, such as C20：5 （ EPA, about 8.9%- 35.1% ）, C22：6 （ DHA, about 10.7%- 22.6% ） ; the content of n - 3 unsaturated fatty acids in sea fish oil soft capsules was about 22.5%~55.7%, the ratio of n -6 unsaturated fatty acids and n - 3 unsaturated fatty acids was about O. 1 ~ O. 7 and the ratio of EPA and DHA was 0.8 - 1.9.
