Abstract

Background: In Antiquty, The treebarks were used as medication. The most of treebarks have tannin that is important material in vegetative universe. this important plant material has Antiseptic and protein coagulating properties.Objective: The purpose of this investigation is quantitating of tannin from the treebarks such as BLACK WALNUT, OAK, ALDER, HORN BEAM and BEECH.Methods: The total extractive matrials obtained according TAPPI standard.The bark phenolic compound were obtained according Calberg and Kurth scheme. Tannin was evaluated by Tanoform method.Results: Experiments showed that the total extractive content of these species were 29.8, 23.2, 17.9, 16.8 and 16.7 percent respectively. Also, it was shown that the total phenolic materials were 26.3, 21.2, 13.6, 12.9 and 14.0 percent respectively. By sequential precipitation, Flobatannins, FLOBAPHENS and FLAVONOIDS were separated and measured quantitavely. Also the percentage of tannin in extractive materials of species were evaluated between 40-50%. Conclusion: Generally, The total extractive materials in this study were obtained between 17-30 percent which almost half of that is tannin. The minimum and maximum of tannin belong to BEECH and walnut Species respectively. Hydrolysable and condensed tannins have medical and industries application.
