摘要
用氯仿-甲醇法提取大黄鱼鱼卵的粗脂肪,经甲酯化处理,用气相色谱法对其脂肪酸的组成进行分析。结果显示大黄鱼鱼卵湿基总脂肪含量达19.6%,干基总脂肪含量达44%,磷脂占总脂肪比例为61.2%,胆固醇占总脂肪比例为3.2%,而且大黄鱼鱼卵还含有丰富的ω-3PUFA多不饱和脂肪酸,其EPA和DHA之和达到了25.5%。
The lipid content and fatty acid composition of the roe from pseudosciaena crocea were de- termined. The crude fat of sample roe was extracted by chloroform： methanol （2 ： 1 ）, and methylated. The fatty acid methyl esters were analyzed by GC. The results showed that the fat content of wet and dry weight was 19.6% and 44%, respectively; the proportion of phospholipid and cholesterol was 61.2% and 3. 2% ; the roe of pseudosciaena crocea contain abundant ω -3PUFA polyunsaturated fatty acid. The total content of EPA and DHA in lipid reached to 25.5%.
