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.
