Identification and Comparative the Extractives Chemical Components in Natural and Planted Cypress Tree by GC/MS Methods

Cypress tree is one of the species with unique natural durability and there are in a lot of natural and planted forests in Mediterranean region in Iran. In this study, three trees from two species of natural and planted cypress tree were randomly cut down in Hasan-Abad region of Chalous city. Then from each tree three disks were slected, then and wood flour and prepared and the extractives were measured according to TAPPI standard. The results showed that the extractives decrease in the longitudinal direction. Of tree The average of extractives in natural and planted cypress tree are 7.52 and 2.57 percent respectively. Then wood flour was washed by toluene – ethylic alcohol with the 2:1 ratio, and the extractives residue was added BSTFA reactor and samples kept in Ben Marry Bath in 70oC for an hour, then analyzed by GC/MS. For the identification of component the GC diagram which shows abundance and retention time of each compound, calculation of quartz index and Adams table were used. Generally, 14 compounds in natural and 12 compounds were definited in planted cypress tree. The isophyllocladene, 9-octadecenamide, cinnamaldehyde-2-hexyle, bourbonanone and 1h-naphtho[2,3-c] pyran-3-acetic acid were the important components in either species and these compounds are very important role in durability of cypress tree.
