Py-GC-MS Analysis on Benzene-Alcohol Extractives of Eucalyptus urophydis Wood for Fine Indoor Environment

In order to evaluate the safety of Eucalyptus wood interior, Eucalyptus urophydis wood was used and extracted in benzene-alcohol solution, and its extractives were identified by Py-GC/MS. The main and abundant constituents of 350°С pyrolysis products were 1-phenanthrenecarboxylic acid, 1,2,3,4,4a,9,10,10a-octahydro-1,4a-dimethyl-7-(1-methylethyl)-(5.38%), stigmasterol,22,23- dihydro- (4.67%), 3'-chlorooxanilic acid n'-(3-ethox y-4-hydroxybenzylidene)hydrazide (4.13%), stigmast-5-en-3-ol, oleate(3.83%), 2-ethylacridine(3.32%), etc. The main and abundant constituents of 600°Сpyrolysis products were decanoic acid, 1,2,3-propanetriyl ester(33.8%), dodecanoic acid, 1,2,3-propanetriyl ester(8.03%), decanoic acid, 1,2,3-propanetriyl ester(3.99%), 1-chloromethyl-1-(2-propenyloxy)-1-silacyclohexane(3.98%), etc. So there was much biological medicine and health care composition in Eucalyptus urophydis wood. And the wood was safety.
