摘要
采用内标法对月见草油γ-亚麻酸绝对含量进行测定,将月见草油中的脂肪酸甘油酯甲酯化转化为脂肪酸甲酯进行气相色谱分析,从而得出月见草油的γ-亚麻酸绝对含量。采用这种方法测得的结果比传统的简易酯化法和外标法更准确,更直接。
The absolute content of γ-linolenic acid in evening promrose oil were determined by internal standard method. The glycerol esters of fatty acids in evening primrose oil was esterified into fatty acid methyl esters,and tested by GC, then the absolute content of γ- linolenic acid in evening primrose oil was obtained. The result obtained by this method was more accurate and direct than that of the traditional simple esterification method and external standard method.
