Abstract

The aim of this study was accomplished on identification and comparison of chemical compounds in wood of maple tree. For this purpose, the samples were chosen randomly from persuan maple and Caucasian maple tree in Nowshahr's forest region. Then, flour and ash were provided from heartwood, sapwood of maple tree by TAPPI standards. For measured metallic ions, by atomic absorption method. The ions results showed that mn, co, fe, zn, and cu ions in Caucasian maple were more than persuan maple, but k ion was lower. Then extractives were separated from wood flour by acetone and extractives residue transferred to glass vial and was added BSTFA reactive agent to it. 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 are 39 compounds in persuan maple, that benzaldehyde, bis (2-ethylhexyl)phthalate, gibberllin A3 and 1,2-benzenedicarboxylic acid were important components. 24 components identified in Acer leatum that di-limonene, bis(2-ethylhexyl)phthalate,alpha- terpen and alpha-pinene as important components. Comparison of chromatograms showed that di-limonene and bis(2-ethylhexyl)phthalate were exists as 2 common components in persuan maple and Caucasian maple tree. These compounds can very important in durability and consumption its.
