【摘要】 用KOH－CH3OH脂交换法快速甲酯化处理油样，以色谱－质谱－计算机联用仪对本地市售菜油中脂肪酸的成分进行了分析，共鉴定出17种组分。其中以芥酸、亚油酸、油酸、花生烯酸、亚麻酸、棕榈酸、硬脂酸、山脊酸为主。芥酸含量高达34％，表明所检菜油属高芥酸菜籽油。更多还原

【Abstract】 Sample of rapeseed oil was esterfied by KOH-CH3OH, Then it was determined by cap-illary GC/MS. fatty acid in rapessed oil have thus been determined with a main compositionof 13 - Docosenoic acid (34. 2 % ), 9, 12 - Octadecadienoic acid (14. 8% ), 9-Octadecenoinacid(12N), 11 -Eicosenoic acid(11. 4% ), 9, 12, 15-Octadecatrienoic acid (6. 67%), Hex-adecanoic acid (5. 5%), Octadecanoic acid (3. 8%), Docosanoic (2. 7%).更多还原
