| The aim of this study was the identification and comparison of organic chemical compounds in wood and bark of hornbeam and ironwood trees. For this purpose, the samples were chosen randomly from heartwood and bark of hornbeam and ironwood trees in Nowshahr's forest region. Then, flour and ash were prepared from heartwood and bark of hornbeam and ironwood trees separately by TAPPI test methods. Then extractives were separated from wood flours by acetone and extractives residue was transferred to glass vial and BSTFA reactive agent was added. Then samples were injected to the GC/MS device for 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 19 and 25 compounds in wood and bark of hornbeam tree, that Octa-methyl-Cyclotetrasiloxan and bis (2-ethylhexyl) phthalate were the important and common components in wood and bark of hornbeam. There were 66 and 18 components identified in wood and bark of ironwood tree that decanese, tetradecanese, hexadecanese, 1,2-benzenedicarboxylic acid and bis (2-ethylhexyl)phthalate were important and common components in bark of ironwood. These compounds can be very important in durability and consumption of wood and bark of hornbeam and ironwood trees. Comparison of chromatograms showed that bis (2-ethylhexyl) phthalate exists as a common components in heartwood and bark of hornbeam and ironwood trees. | ||
