| 摘 要： | 采用铁锅炼制提取斑点叉尾鮰内脏鱼油,然后加酸使其甲酯化,以气相色谱/质谱法分析鱼油中的脂肪酸.结果斑点叉尾鮰内脏纯油脂中鱼油达到99%.从鱼油中共鉴定出15种成分,有饱和脂肪酸及不饱和脂肪酸,还有少量烷烃类物质.不饱和脂肪酸含量为76.40%,其中多不饱和脂肪酸为18.03%,以C18∶ 2(16.23%)为主,单不饱和脂肪酸为58.37%,以C18∶ 1(54.88%)为主.饱和脂肪酸含量为20.91%,主要有C16∶ 0 (15.84%)和C18∶ 0(4.29%),多是低于C18以上的中长链脂肪酸.因此斑点叉尾鮰油脂可作功能性脂肪酸的重要膳食来源.

| Abstract: | The composition of fatty acids in Ictalurus punctatus oil was identified and quantified by gas chromatography(GC) /electrom inpact(EI) mass spectrometry(MS) . The acid catalysis method was used to convert fatty acids to methyl-esters and the total lipids in pure fat of Ictalurus punctatus were about 99%. Twenty-three fatty acids were identified in the current study. The main types of fatty acids found in the oils were normal monounsaturated,polyunsaturated fatty acids and alkanelparaffin. Unsaturated fatty ... |
