Determination of Chemical Components of Benzene/Ethanol Extractives of Eucalyptus urograndis Wood by GC/MS
The chemical components of benzene/ethanol extractives of fresh Eucalyptus urograndis wood chips were separated and identified by GC/ MS after enriching. Relative content of each chemical component was determined by area normalization. Thirty compounds representing 87.88％ of the extractives which take on 42 peaks were identified. The most abundant and valuable constituents were 1,2-benzenedicarboxylic acid, diisooctyl ester (17.53％), 1,2- benzenedicarboxylic acid, bis (2- methylpropyl) ester (8.48％), dibutyl phthalate (8.12％), butanedioic acid, methyl-, bis (1-methylpropyl) ester (7.02％), hexanedioic acid, bis (2-methylpropyl) ester (6.89％), 2, 6, 10, 15, 19, 23-hexamethyl-2, 6, 10, 14, 18, 22- tetracosahexaene (4.53％), hexadecanoic acid, ethyl ester (3.77％), 2-isopropyl-1-methylnaphthalene (2.97％), hexacosane (2.63％), di (2-ethylhexyl) adipate (1.98％ ) , octacosane (1.93％), salsoline (1.90％ ) and so on.
