小茴香超临界CO_2萃取产物脂肪酸成分分析

Studies on composition of fatty acids of supercritical CO_2 fluidextraction product of Foeniculum vulgare Mill seeds

通过脂肪酸的衍生化处理，再利用色谱（GC）和色谱一质谱（GC－MS）等分析手段，对小茴香超临界CO2萃取产物的脂肪酸成分进行了剖析，共鉴定出九种脂肪酸，其中，十八碳一烯酸、十八碳二烯酸和棕榈酸是其主要成分，分别占脂肪酸总量的75．12％、15．18％和5．34％．

The composition of fatty acids of supercritical CO2 fluid extraction product of Foeniculum vulgare Mill. seeds was studied by means of derivation of fatty acids GC and GC-MS. 9 components were indentified. Among them, the major constituents are octadecenoic acid (75.12%), octadecadienoic acid (15.18%) and hexadecanoic acid (5. 34%).
