小茴香萃取物中脂肪酸成分的GC-MS分析

Analysis of fatty acids in Foeniculum vulgare Mill. seeds by gas chromatography-mass spectrometry

对宁夏固原种植的小茴香籽油用正己烷进行了回流提取 ,萃取物经皂化和甲酯化反应处理后 ,利用气相色谱 质谱 (GC MS)进行分析 ,鉴定了产物中的脂肪酸组分 .结果表明 ,17种脂肪酸中 ,含量最高的是十八碳烯 5 酸(78.5 6 2 % ) ,其次是十八碳二烯酸 (8.35 2 % )、棕榈酸 (7.2 5 9% )和硬脂酸 (2 .10 3% ) .

Fat was obtained by distillation from Foeniculum vulgare Mill. seeds, and analyzed by gas chromatography mass spectrometry (GC MS)and derivation technology.Seventeen compounds were identified from its fats. The main compositions of fatty acid in Foeniculum vulgare Mill. seeds are octadec 5 enoic acid (78.56%),octodeca 6,9 dienoic acid (8.35%),hexadecanoic acid (7.26%) and octadecanoic acid (2.103%).
