| Résumé: | Sweet locust and False Acacia are important species of northern forests region with wood having good durability. In this study, three disks from each species were randomly cut in Nowshahr forest region. For homogenous sampling, first wood flour was prepared from each disk according to TAPPI standards and then mixed together. Acetone was used to remove extractives from both Sweet locust and False acacia wood flour. Extracts were analyzed by GC/MS. For the identification of compounds, GC diagram which shows abundance and retention time of each compound and calculation of quartz index and Adams table were used. The results showed that there are almost 150 compounds in False Acacia wood, and among them Resorcinol(19.47%),1,3-Benzendiol(6.92%) ,Stigma sterol (5.45%), 9-Octadecenoic acid(3.55%),1H-Imidazol(3.08%),Gamma-sitosterol (2.77%) and Gamma-Terpinene(0.22%) were the predominant compounds. There are 37 compounds in Sweet locust wood, that 1,2-Benzenedicarboxylic acid (90.38%),Stigmast-4-en-3-one(2.62%),Resorcinol(1.07%),Silicon grease (0.73%), Gibberellins A3(0.14%) and Phenol(0.09%) were important compounds. Resorcinol and 1, 2-Benzenedicarboxylic acid occurs both in Sweet locust and False acacia woods. The presence of high percentage of Resorcinol (20%) in Sweet locust and 1,2-Benzenedicarboxylic acid (90.38%) in False acacia are attributed for the durability of these species. |
