The extractives from masson pine (Pinus massoniana L.) wood would not only consume bleaching agent and other additives, but also aggravate environmental pollution. Therefore, Py-GC/MS was used to analyze the high-grade resource recovery of acetone extractives of masson pine wood. Relative content of each component was determined by area normalization. The main and abundant constituents of 590degC pyrolysis product of masson pine wood were 1-phenanthrene carboxylic acid, 1,2,3,4,4a,9,10,10a-octahydro-1,4a-dimethyl-7-(1-methylethyl)-, [lR-(1.alpha.,4a.beta.,10a.alpha.)]-(17.51%), oleic acid(17.13%), pimaric acid(12.64%), 1-Hydroxy-3,7,8-trimethoxy xanthen-(6.08%), 9H-thioxanthen-9-one, 2-methyl-(4.49%), hexadecanoic acid(3.12%), 1-phenanthrenecarboxylic acid, ,2,3,4,4a,9,10,10a-octahydro-1,4a-dimethyl-7-(1-methylethyl)-,1S-[(1.alpha.,4a.alpha.,10a.beta.)]-(2.56%), orphinan-2,6-diol, ,5- epoxy-N-methyl-(2.96%), phenanthrene,-ethenyl-1,2,3,4,4a,4b,5,6,7,8,8a,9-dodecahydro-1,1,4b,7-tetramethyl-,4aS-[(4a.alpha.,4b.beta.,7.alpha.,8a.alpha.)]- (2.41%),etc. The analytic result suggested that the benzene/ethanol extractives of masson pine wood can be used as materials of biomedicine, flavor, skin care and cosmetic, and bioenergy.
