chemical composition of the essential oil from flowers of calycanthus floridus l. var.oblongifolius (nutt.) d.e. boufford & s.a. spongberg from iran

the essential oil obtained by hydrodistillation of flowers of calycanthus floridus l. var.oblongifolius (nutt.) d.e. boufford & s.a. spongberg, planted in sabzevar, khorasan province(iran), was analyzed by gc and gc/ms. eighteen compounds representing 90.1% of theflower oil of calycanthus floridus l. var. oblongifolius were identified, among them 1,8-cineol(33.1%), bornyl acetate (14.1%), α-pinene (10.2%), elemol (8.2%), β-pinene (8.6%) andα-terpinyl acetate (5.8%) were the major ones. in this essential oil, oxygenated monoterpenes(57.2%) predominated over monoterpene hydrocarbons (22.7%) and sesquiterpenes (10.2%).nonterpene hydrocarbons were not found among the identified components.
