GC-MS analysis of fatty acid composition in the leaves of Eucalyptus urophylla × E.grandis by two extraction methods
摘要
Abstract
The fatty acids in Eucalyptus urophylla × E.grandis (DH32-29) leaves were extracted by two methods (Soxhlet extraction and ultrasonic extraction),and its compositions were analyzed by GC-MS.The results showed that there were six kinds of fatty acids,four of them were saturated fatty acids,tetradecanoate,hexadecanoic acid,octadecanoic acid and eicosanoic acid,two of them were polyunsaturated fatty acids,(Z,Z,Z)-9,12,15-octadecatrienoic acid and (Z,Z)-9,12-octadecadienoic acid,and the main fatty acids were (Z,Z,Z)-9,12,15-octadecatrienoic acid,hexadecanoic acid,and (Z,Z)-9,12-octadecadienoic acid.Extraction rate of Soxhlet method (7.64％) was higher than that of ultrasonic extraction (6.12％) significantly.The polyunsaturated fatty acids was accounting for 21.30％ of total extraction by Soxhlet extraction,which were mainly (Z,Z)-9,12-octadecadienoic acid (20.67 ％) and (Z,Z,Z)-9,12,15-octadecatrienoic acid (0.63％).关键词
