Determination of Biomedicine Resource of Benzene/Ethanol Eztractives of Flesh Eucalyptus urophydis Chips by Py-GC/MS
The extractives of Eucalyptus urophydis wood consumes more bleaching agents which seriously affect the quality of pulp and paper, and increases more difficulties on the treatments of wastewater and black-liquid from wood industry, especially pulp-and paper-making industry. Therefore, In order to solve the problem, Py-GC/MS was used to analyze the highgrade resource recovery of benzene/ethanol extractives of flesh E. urophydis wood. Relative content of each component was determined by area normalization. The main and abundant constituents of 590℃ pyrolysis product of Eucalyptus urophydis bark were 3,7-dihydroxy-9-methoxy-1-methyl-6Hdibenzo B,Dpyran-6-one(5.01). 1-phenanthrenecarboxylic acid,1,2,3,4,4a,9,10,10a-octahydro-1,4a-dimethyl-7-(1-methylethyl)-(4.19), ergosta-4,6,22-trien-3.beta.-ol(4.07), phenol, 2,6-dimethoxy-(2.99), hexadecanoic acid(2.96), acetic acid(2.86), ethanone, 1-(3-methoxyphenyl)-(2.83), phenol, 2-methoxy-(2.38), 1-phenanthrenecarboxylic acid, 1,2,3,4,4a,9,10,10a-octahydro-1,4a-dimethyl-7-(1-methylethyl)-, methyl ester(2.05), germanicol(2.00), benzoic acid, 4-phenyl(phenylimino)methoxy-, methyl ester(1.97), 3-buten-2-one, 4-(2,6,6-trimethyl-1-cyclohexen-1-yl)-(1.86), 4.alpha.-Methylcholest-7-en-3-one(1.78), phenol, 2-methoxy-4-(1-propenyl)-(1.58), phenol, 2,6-dimethoxy-4-(2-propenyl)-(1.55), cedrol(1.12), hexadecanoic acid, ethyl ester(1.08), brucine(1.02), bis(2-ethylhexyl) phthalate(0.91), 9,12-octadecadienoic acid (Z,Z)-(0.83), beta.-sitosterol(0.84), etc. The analytic result suggested that the benzene/ethanol extractives of E. urophydis chips can be used as materials of biomedicine, skin care and cosmetic, bioenergy and flavor.
