Eucalyptus biomass was used as the fine nutritive material for medical microbiology. However, although single composition of woody biomass has been succeed in preparation for medical microbiology, but green and high efficient separation of woody biomass was still a very difficult. Therefore, the molecule characteristics of Eucalyptus hemicelluloses were investigated and analyzed by NMR and FTIR. The result showed that the three Eucalyptus hemicelluloses had a structure composed of the (1 -> 4)-linked beta-D-xylopyranosyl backbone with 4-O-methyl-R-D-glucuronic acid attached to O-2 of the xylose residues. In Eucalyptus urophydis, Eucalyptus urophynis and Eucalyptus camaldulensis hemicellulosic samples, xylose was an extremely predominant component sugar which relative percent were 80.06, 77.80% and 77.54%, respectively. And Eucalyptus ccunaldule.nsis hemicelluloses had a higher molecular weights than ones of other two Eucalyptus.
