Abstract :
. The results of this study showed that the average of extractives in leaves of planted eldar pine and plane tree were 16.2 and 14.4 percent respectively. Then wood flour was washed by acetone. To the extractives residue was added BSTFA reactor and samples kept in Ben Marry Bath in 70oC for an hour, and they were analyzed by GC/MS. For the Identification of compounds were used GC diagram which shows abundance and retention time of each compound, and calculation of quartz index and Adams table. The result showed there are 20 compounds in leaves of plane tree that n-Hexadecanoic acid(24.28%), Heptadecan-8-carbonic acid(18.05%), Octadecanoic acid(14.1%) and E Vitamin (2.81%) were important compounds. There are and 45 compounds in leaves of elder pine tree that 9,12,15-Octadecatrien-1-ol(11.49%), 4-Methylmannose (10.68%), Mome Inositol(9.65%) and Phytol(0.64) were important compounds. there were Decan, Dodecan, Neophytadiene and Octadecanoic acid as 5 common compounds in leaves of planted elder pine and plane tree.
