Abstract

Introducing the most suitable method to obtain useful materials and reapplication and multiple- use of materials and natural resources is one of the most effective methods for preserving environment. TANNIN, one of the most important substances in OAK tree, has various applications in pharmaceutical, ink, leather, oil well drilling, wood coating, and wood glue industries. This study was conducted to achieve the most suitable method of TANNIN extraction from the fruit of OAK.Out of 36 species and sub-species, 10 species and sub-species which cover a more extended area of Iranian woods in north Alborz, Arasbaran region and the west region of Zagros Mountains, were selected in term of their dispersion and then, 5 samples of each specie were taken. The TANNINs of the samples were extracted and measured through the four methods of MACERATION, DECOCTION, PERCOLATION and SOXHLET extractor.The results of the study reveals that Quercus brantii belangri has the most amount of tanin with 9.7 percent and this rate for other 9 species and sub-species which cover a more extended area of Iranian woods is between 3.2 and 7.5 percent.
