Abstract

The aim of this study was accomplished on identification and comparison of chemical compounds in wood of Alnus subcordata and Alnus subglotinosa. For this purpose, the samples were chosen randomly from Alnus subcordata and Alnus subglotinosa in Nowshahr's forest region. So that, first, flour and extractives by acetone were provided by TAPPI standards methods. Then, extractives residue transferred to glass vial and was added BSTFA reactive agent to it. After 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 99 compounds in alnus subcordata, so that, dibutyl phthalate (9.15%), 2,2-oxybis-ethanol(6.62%), 1,2-benzendicarboxylic acid(2.63%) and squalene(0.48%) were important compounds. In alnus glutinosa, from 127 indentified compounds, butanedioic, monomethyl ester(10.88%), isopropenoxypropan-2-ol(8.82%),3,5-dioxaundecane(7.73%),gamma-sitosterol (3.53%) and vanillin(0.39%) were important compounds. Comparison of chromatograms mention samples showed that there are 12 common components in Alnus subcordata and Alnus subglotinosa, that tetradecane, hexadecane,heptadecane, isopropenoxypropan-2-ol and bis(2-ethylhexyl)phthalate were important components. Some of these compounds can very important in durability and consumption Alnus subcordata and Alnus subglotinosa.
