Abstract
Holocellulose , alphacellulose and
lignin, three major cell wall components, of severe eucalyptus species viz, E. camaldulensis ehnh , E. clurtodora hook, E. maculate hook, E.mannifera mudia. E. melanophloia, F. muell , E. microtheca , F. muell, and E. tereticornis Sm, were investigated from extractive-five wood of trunks and branches . amount of holocellulose ranged between 67.80-
77.93% in trunkwood and 67.22-
76.19% in branch-wood , alphacellulose 40.9-47.1% im trunkwood and 36.25-43.84% in
branch wood and lignin 22.02-32.28 % in trunkwood and 23.45-32.77 % in branchwood. There was not much variation in the amount of these polysaccharides among the species investigated.
