Abstract :

In essential oils of stem, leaf and fruit of A. spicigera, 28,20,20 compounds, which accunting for 100% ، 99% ،99% /47 of the total oils of stem, leaf and fruit were identified, respectively. The main components of the essential oils of stem, leaf and fruit were Borneol (19/26 % ، 22/26% ، 07/22% ), 1,8-cineole (34/20% ، 76/22% ، 30/18%), Comphor (34/10% ، 97/11% ، 39/12 %), Bornyl acetate(74/9 % ، 30/8 % ، 24/8 %), respectively. In oils of A. spicigera, oxygenated monoterpene compounds were the main constituents. Also, in essential oils of stem, leaf and fruit of A. chamaemelifolia, 17,20,31 compounds, which accunting for 33/97% ، 14/98% ،70/98% of the total oils of stem, leaf and fruit were identified, respectively. The main components of the essential oils of stem, leaf and fruit were Spathulenol(53/11 % ، 48/13% ، 43/20% ), Cubenol (44/6% ، 86/15% ، 01/26%), Santolina trien (79/22% ، 78/18% ، 66/1 %), Caryophyllen oxide(90/9 % ، 95/4 % ، 03/6 %), respectively. In oils of A. chamaemelifolia, oxygenated monoterpene compounds and monoterpene hydrocarbons were the main constituents, respectively.
