摘　　要：采用索氏提取法提取莱菔(Raphanussativus)种子中的脂肪酸成分,进行甲酯化处理后用气相色谱-质谱联用技术分离和鉴定脂肪酸成分的组成和含量。结果表明,从莱菔子中共分离鉴定出12种脂肪酸成分,占总量的99.32%,主要包括芥酸(32.47%)、油酸(29.07%)、亚油酸(9.45%)、亚麻酸(8.41%)、棕榈酸(4.31%)和硬脂酸(2.08%)等脂肪酸,其中饱和脂肪酸占9.25%,不饱和脂肪酸高达90.07%。The fatty acids from the seeds of Raphanus sativus were extracted with petroleum ether by Soxlet extraction. The extracted fatty acids were esterified and analyzed by gas chromatography-mass spectrometry. Twelve fatty acids were detected and identified, amounting to 99.32% of the total fatty acids, mainly including 13-docosenoic acid （32.47%）, 9-octadecenoic acid （29.07%）, 9,12-octadecadienoic acid （Z,Z） （9.45%）, 9,12, 15-oetadecatrienoic acid （8.41%）, hexadecanoic acid （4.31%）, and octadecanoic acid （2.08%）. The saturated fatty acids and unsaturated fatty acids were 9.25% and 90.07% in amount, respectively.
