Cellulose is the most abundant renewable biopolymer on the earth. In recent years, the demand for biodgradable and biocompatible polymer materials has been grown extensively. Although pure cellulose is biocompatible but the majority of pulps used in paper industries are obtained by chemical pulping processes. The chemical pulping process affect the biocompatibility of the cellulose fibers. Thus, obtaining biocompatible cellulose from other renewable resources is the interest of many researchers. In this study, we assumed that pepper can contain remarkable amounts of lignocellulosic compounds. In this regard, the pepper flour was used for determining the amount of lignocellulosic compounds according to TAPPI standard methods. The morphological observation of pepper powder showed parenchyma cells containing nutritions. The composition of the lignocellulosic compounds was determined by Soxhlet extraction using different solvents. The result of this study showed that pepper contains 31% holocellulose, 62% cellulose and 18% lignin, %14 extractives and 6% ash. The amount of cellulose and holocellulose of the pepper is comparable with that of birch Kraft pulp. According to these results, it can be concluded that pepper can be a suitable renewable resource for obtaining biocompatible cellulose.
