| Abstract | ||
| Sycamore tree (Platanus orientalis) is one of the species that planted in parks and urban green spaces and forests region of Tehran and other cities in Iran. The aim of this study was to identify and compare the phenolic chemical components in wood and bark of planted sycamore tree. In this study, three trees were randomly selected and felled in planted forest region of Tehran. Three disks were prepared from each tree and according to TAPPI standard tests, first wood flour and then the extractive (%) were separated from wood flour using acetone solvent. To identify of extractives, about 1mg extractives was mixed with 30 microliters BSTFA and the samples were analyzed using a gas chromatograph connected to mass spectrometry (MS) with a detector. Samples were then injected into the injection section of GC/MS using a Hamilton syringe. The compounds identification was performed using GC diagrams, abundance and retention time of each compound, calculation of quartz index and Adams table. The results showed that the average of extractives in wood and bark of the planted oriental plane tree were 3.6 and 16.6 percent, respectively. GC-MS results showed that 17 specification compounds were found in the plane wood. Furthermore, Hexadecanoic acid (22.18%), Heptadecan-8-carbonic acid (15.24%), and 1, 2-Benzenedicarboxylic acid (12.08%) were the most important compounds. The 41 compounds were identified in the plane bark that 9-Octadecanoic acid (19.88%), n-Hexandecanoic acid (16.41%), 9, 12-Octadecanoic acid (9.66%) and Gamma-Sitosterol (2.09%) were the most important compounds. In addition, the results showed that 9-Octadecanoic acid, Hexadecane, Dodecan, Tetradecan, Eicosan, Octadecane, and Decane were the 6 common compounds in the wood and bark of sycamore tree, as well | ||
