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%.
