As a waste in pulp, the acetone extractives of Eucalyptus urograndis wood severely polluted the water and wasted a lot of bleaching agents. Therefore, Py-GC/MS was used to analyze high-grade bioenergy utilization of acetone extractives of Eucalyptus urograndis wood. The relative content of each component was determined by peak area normalization. 33 compounds in the extractives were identified. The mainly abundant constituents were ergosta-4,6,22-trien-3.alpha.-ol (12.95%), carbon dioxide (12.02%), cyclopentadecanone, 2- hydroxy- (8.21%), .beta.-sitosterol (7.6%), 1,2-benzenediol (5.97%), phenol, 2,6-dimethoxy- (5.45%), R-(-)- cyclohexylethylamine (4.64%), vitamin E (4.51%), phenol, 3,5- diethyl- (4.38%), acetone (4.16%), 4.alpha.-methylcholest-7-en-3- one (3.54%), 1,2,3-benzenetriol (3.33%), 1
