Özet
Bu çalışmada, orman işletmelerinde kesim sonrası ortaya çıkan doğu ladini (Picea orientalis) kabukları ve ahşap levha endüstrisinde levha üretimi sonrası ortaya çıkan endüstriyel atık meşe (Qercus spp.) kabuklarının kimyasal bileşimi temel odun analizleri ve fenolik bileşik analiz metotlarıyla incelenmiştir. Kabuklarda kül tayini sonuçlarına göre Artvin ve Trabzon ladin örneklerinde % 4.31 ve % 3.99 kül bulunurken meşe kabuğunda % 10.02 gibi yüksek sonuç belirlenmiştir. Sıcak su çözünürlüğünün ladin örneklerinde meşeye göre daha yüksek olduğu ortaya konulmuştur. Artvin ladin, Trabzon ladin ve meşe kabuklarında kalıntı lignin sırasıyla % 19.53; % 20.61 ve % 18.49 olarak belirlenirken ?-selüloz miktarı için % 37.28; % 37.92 ve % 41.59 değerleri elde edilmiştir. Toplam fenol tayini ve butanol HCl yöntemi sonuçlarına göre Artvin ladin kabuğu en yüksek değerlere sahiptir. Ladin ve meşe kabuğu örneklerinde hidrolize tanenler olan gallo tanen bulunurken ellag taneni içeriği belirlenememiştir
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 ?-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
