Abstract

The aim of this study was accomplished on identification and comparison of the phenolic chemical components in wood of Siberian elm, Common elm and Mountain elm tree. For this purpose, the samples were chosen randomly from of elm trees in Nowshahr's forest region. Then, flour and ash were provided from these woods of species (separate) by TAPPI standards. After samples prepared, samples were injected to the GC/MS device for it analysis. Identification of compounds was done by retention time of each compound, calculation of Quats index and Adams table. The result of GC-MS showed that there were 116, 41 and 18 compounds in wood of Siberian elm, Common elm and Mountain elm tree, respectively. That 5-Hydroxy-calamenen (21.23%), 1-Naphthalen carboxylic acid (15.41%), Naphthalene (0.96%) and phthalate (1.00%) were the most important ‎ compounds in wood of Siberian elm. The 5,6,7,8-tetrahydro-2,5-dimethyl-8-(1-methylethyl)-1-Naphthalenol(18.59%), Gamma-Sitosterol (13.44%), bis (2-ethylhexyl) phthalate (12.28%) and 1-Naphthalen carboxylic acid (5.73%) were the most important ‎ compounds in wood of Common elm, too. There were the bis (2-ethylhexyl) phthalate (93.40%), 4-(N-Isopropylamino)-6-phenyl (1.89%), 5, 6, 7, 8-tetrahydro-1-naphthalenol (1.80%) and 8-methoxy-1-acetonaphthone (0.27%) as the most important ‎ compounds in wood of Mountain elm tree. In addition, the results showed that 9,12-Octadecanoic acid, Hexadecane, Dodecan, Tetradecan, 1-Naphthalen carboxylic acid and bis (2-ethylhexyl) phthalate were the 6 common compounds in the wood of Siberian elm and Common elm tree. There were the Qoinindolin, Tetradecan, Hexadecanoic acid and bis (2-ethylhexyl) phthalate were the 4 common compounds in the wood of Siberian elm and Mountain elm tree. There were the Tetradecan, Hexadecanoic acid and bis (2-ethylhexyl) phthalate were the 3 common compounds in the wood of Common elm and Mountain elm tree, too. The gas chromatographs showed that Tetradecan and bis (2-ethylhexyl) phthalate were the 2 common compounds in three spices of elm trees.
