Abstract :
Wood extractives for bioenergy with high additional value is looked upon as a strategy task. In this paper, the chemical components in the benzene/ethanol extractives of Eucalyptus urophylla wood were isolated and identified by Py- GC/MS so as to increase economic benefits. The relative content of each component was determined by peak area normalization. 73 compounds in the extractives were identified. The mainly abundant constituents were ergosta-4,6,22-trien-3.beta.-ol (11.6%), .beta.-sitosterol (10.02%), hexadecanoic acid (7.18%), phenol, 2,6-dimethoxy- (6.46%), carbon dioxide (5.62%), 9,12- octadecadienoic acid (Z,Z)- (5.5%), 2-octanamine, n-(l- methylheptyl)- (3.27%), benzene, 2-methoxy-l,3,4-trimethyl- (3.16%), ethyne, fluoro- (2.77%), 4.alpha.-methylcholest-7-en-3- one (2.36%), 2,3,5,6-tetrafluoroanisole (2.22%), squalene (2.13%), oleic acid (2.13%), (z)6,(z)9-pentadecadien-l-ol (2.06%), phenol, 4-ethyl-2-methoxy- (2.03%), etc. The most components from benzene/ethanol extractives of Eucalyptus urophylla wood could be used as fine bioenergy, biomedicine, and other high additional value products.
