摘要: 本文采用索氏提取法提取苣荬菜中脂肪酸,再进行甲酯化处理,以气相色谱-质谱联用仪分离和鉴定脂肪酸的组成和含量。结果表明:由苣荬菜中分离鉴定出12种脂肪酸,占脂肪酸总量的90.21%,不饱和脂肪酸占脂肪酸总量的52.09%,饱和脂肪酸占脂肪酸总量的38.12%。

Abstract: The fatty acids in chicory was extracted by Soxhlet extraction. The fatty acids in the oil were esterified and then analyzed by gas chromatography-mass spectrometry (GC/MS). 12 fatty acids were identified in the chicory. The contents of the identified fatty acids accounted to 90.21%, while, the unsaturated fatty acids were 52.09%, and saturated fatty acids were 38.12%.
