Abstract

Objective To analyze fatty acid compositions in seeds oil of Cydonia oblanga M. Methods The seeds of Cydonia oblanga Mill.was extracted by soxhlet extraction,the fatty acids in the oil were esterified by potassium hydroxide-methanol and then analyzed by gas chromatography-mass spectrometry(GC/MS). Results Twelve fatty acids were identified and the contents of unsaturated fatty acids were 85.46%.Among them,the palmitate acid was 8.30%,the oleic acid was 31.65%,the linoleic acid was 51.86% and the linolenate acid was 1.90%,respectively. Conclusion The main components are unsaturated fatty acids in seeds of Cydonia oblanga Mill.,among which the relative contents of essential fatty acid linolenic acid and linoleic acid are rich and have a development value.
