以不同来源的橄榄油、胡麻油、芝麻油和菜籽油为材料，通过碱法甲酯化，利用 GC–MS 法对四种植物油脂脂肪酸组成进行分析。结果表明，四种植物油脂中，橄榄油和胡麻油的不饱和脂肪酸含量高，分别为77.16%和82.25%；橄榄油中油酸含量（62.95%）高，亚麻酸含量（0.87%）低；胡麻油中亚麻酸含量（62.34%）高，油酸含量（8.03%）低；菜籽油的必需脂肪酸含量低，而芝麻油可能掺伪。
以不同來源的橄欖油、鬍痳油、芝痳油和菜籽油為材料，通過堿法甲酯化，利用 GC–MS 法對四種植物油脂脂肪痠組成進行分析。結果錶明，四種植物油脂中，橄欖油和鬍痳油的不飽和脂肪痠含量高，分彆為77.16%和82.25%；橄欖油中油痠含量（62.95%）高，亞痳痠含量（0.87%）低；鬍痳油中亞痳痠含量（62.34%）高，油痠含量（8.03%）低；菜籽油的必需脂肪痠含量低，而芝痳油可能摻偽。

The fatty acid compositions of olive oil,linseed oil,sesame oil and rapesee d oil were analyzed by GC/MS after esterification through potassium hydroxide. It showed that the content of polyunsaturated fatty acids in olive oil and linseed oil were high,77.16% and 82.25%,respectively. The content of oleic acid in olive oil was 62.95%,the content of linolenic acid was 0.87%. The content of linolenic acid in linseed oil was 62.34%,the content of oleic acid was 8.03%. The content of essential fatty acids in rapeseed oil was lower. Sesame oil might be adultered.
