摘要:

对棚栽与野生苣荬菜中脂肪酸进行分析。采用索氏提取法提取棚栽与野生苣荬菜中脂肪酸,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相对含量。结果表明:由棚栽苣荬菜中分离鉴定出10 种脂肪酸,不饱和脂肪酸占30.87%;由野生苣荬菜中分离鉴定出7 种脂肪酸,不饱和脂肪酸占57.3%。

关键词: 苣荬菜, 棚栽, 野生, 脂肪酸, 气相色谱- 质谱联用

Abstract:

A method using GC-MS was presented for the analysis of fatty acid composition of wild chicory and chicory grown in plastic shed. Fatty acids were extracted from samples by Soxhlet extraction method and esterfied with methanol prior to GCMS. A total of 10 fatty acids containing 30.87% unsaturated fatty acids were found in chicory grown in plastic shed and 7 fatty acids from wild chicory were isolated and identified, in which unsaturated fatty acids accounted for 57.3%.

Key words: chicory, chicory grown in plastic shed, wild chicory, fatty acid, GC-MS
