Py-GC/MS Analysis on Biomedicine of Benzene/ethanol Extractives from Eucalyptus camaldulensis Biomass

摘要

The benzene/ethanol extractives of Eucalyptus camaldulensis biomass were identified by Py-GC/MS to find out biomedical application. The main 350°C pyrolysis components were 1 -phenanthrenecarboxylic acid, 1,2,3,4,4a,9,10,1 Oa-octahydro-1,4a-dimethyl-7-( 1 -methylethyl)-(21.22%), .beta.-sitosterol acetate (6.4%), stigmasterol, 22,23-dihydro-(5.87%), ergosta-4,6,22-trien-3.beta.-ol(3.6%), etc. The main 350°C pyrolysis components were 1 -phenanthrenecarboxylic acid, 1,2,3,4,4a,9,10,1 Oa-octahydro-1,4a-dimethyl-7-( 1 -methylethyl)-(23.58%), ergosta-4,6,22-trien- 3.alpha.-ol(6.27%), decanoic acid, 1,2,3-propanetriyl ester(6.1%), 4.alpha.-methylcholest-7-en- 3-one(3.92%), stigmasterol, 22,23-dihydro-(3.57%), stigmastan-3,5-diene(2.61%), etc. And the main 750°C pyrolysis components were 1-phenanthrenecarboxylic acid, l,2,3,4,4a,9,10,10a-octahydro-l,4a-dimethyl-7-(l-methylethyl)- (28.83%), .beta.-sitosterol acetate (5.58%), cholest-8(14)-ene-3,15-dione(4.33%), l,3-butadiene,2-methyl-(3.42%), etc. So the benzene/ethanol extractives of Eucalyptus camaldulensis could be used as biomedicine.
