| description | In this study, the chemical composition of bark from
oriental spruce (Picea orientalis), which occur as a result of logging
production of forestry enterprises, and oak (Qercus spp.) bark, which are
industrial waste of the wood panel industry after board production, were
analyzed by wet chemical analysis of wood and analysis methods of phenolic
compound. Ash content values of the barks obtained from Artvin and Trabzon area
were 4.31% and 3.99%, respectively, while the oak bark samples were 10.02%. Hot
water solubility of the spruce bark samples were higher than the oak bark
samples. Residual lignin contents of Artvin spruce, Trabzon spruce, and oak
were 19.53%, 20.61%, and 18.49%, while α-cellulose contents were 37.28%,
37.92%, and 41.59%, respectively. The results of the total phenol content and
butanol-HCl assay showed that Artvin spruce barks had higher values than other
bark samples. As hydrolysable tannins, there were gallo tannin in the samples
of spruce and oak barks whereas ellagic tannin content has not been determined. |
