Determination of Chemical Components of Benzene/Ethanol Extractives of Chinese-Fir Wood by GC/MS

The chemical components from benzene/ethanol extractives of fresh Chinese-fir wood were separated and identified by GC/MS after enriched. Relative content of each component was determined by area normalization. 18 compounds representing 94.96% of the extractives were identified. The main and abundant constituents were octadecanoic acid, methyl ester(16.95%), nonadecanoic acid, methyl ester (cas) (15.23%), hexadecanoic acid, methyl ester (cas) (7.12%), hexadecanoic acid, ethyl ester (cas) (6.83%), dibutyl phthalate(6.09%), cholest-5-en-3-ol (3a)- ,carbonochloridate(5.45%), isopropyl myristate(4.52%), hexadecane (cas) (4.31%), benzene (cas) (4.09%), 3,7,11,15- tetramethyl- 2-hexadecen-l-ol(4.01%), tetradecanal (cas) (3.62%), 1,2-benzenedicarboxylic acid, bis(2-ethylhexyl) ester (cas) (3.57%), a-cedrene (3.30%), nonadecane(3.14%), 1- tridecanol (2.96%), 1,2-benzenedicarboxylic acid, bis(2- methylpropyl) ester (cas) (2.21%), and so on. The most components of benzene/ethanol extractives of fresh Chinese-fir wood are not only abundant and healthy to human, but also used as bioenergy.
