Chemical Composition Properties of Stem and Branch in Alianthus altissima Wood

Wood chemical constituents such as cellulose, lignin, extractive alcohol-benzene and ash contents of Ailanthus altissima wood of trunks and branches were investigated. In trunk wood amount of cellulose, lignin, extractive alcohol-benzene and ash were 47.18, 25.19, 3.5 and 1.25% respectively, whereas for branch wood the corresponding values were 44.12, 23.86, 3.2 and 1.75% respectively. The amount of cellulose and lignin in the trunk wood and branch wood when compared with other types of wood suggest that relatively high pulp yield can be obtained from them. The result of chemical analysis of branch wood as presented in this report suggests that they can also be a potential source of pulp and paper industry.
