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. In this paper, the chemical components in the acetic ether extractives of Eucalyptus urophylla wood were isolated and identified by Py-GC/MS. The relative content of each component was determined by peak area normalization. 91 compounds in the extractives were identified. The mainly abundant constituents were ergosta-4,6,22-trien-3.beta.-ol (10.43%), 1,2-benzenediol (7.01%), hexadecanoic acid (6.14%), butylated hydroxytoluene (6.01%), 9,12-octadecadienoic acid (Z,Z)- (4.29%), phenol, 2,6-dimethoxy- (3.3%), carbon dioxide (2.56%), 4.alpha.-methylcholest-7-en-3-one (2.56%), phenol, 4-ethyl-2-methoxy- (2.54%), 9,17- octadecadienal, (Z)- (2.3%), ethanone, 1-(3-methoxyphenyl)- (2.09%), phenol, 3,4,5-trimethoxy- (2.04%), hydroquinone, mono-tms (2.04%), oleic acid (1.94%), and so on. The benzene/ethanol extractives of Eucalyptus urophylla wood could be used as fine bioenergy, biomedicine, and other high additional value products.
