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 the flower 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%) and α-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.
