Abstract

The chemical composition of essential oils of leaves of two cultivated species,Eucalyptus loxophleba Benth. and Eucalyptus leocoxylon F. Muell. in the central of Iran were obtained by hydrodistillation and analyzed by gas chromatography, using flame ionization and mass spectrometric detection. A total of thirty nine compounds representing 98.0% of total oil have been identified in the oil of E. loxophleba. 1,8-cineole (39.4%), methyl amyl acetate (19.8%), aromadendrene (10.0%), viridiflorol (6.0%) andα-pinene (5.4%) were the major constituents in the volatile oil of E. loxophleba oil. Forty three components were identified in the E. leocoxylon oil where 1,8-cineole (59.1%), cryptone (15.1%), α-pinene (9.9%), α-terpineol (5.1%) and globulol (5.0%) are considered as the main components. The amount of 1,8-cineole as the main component was higher in the oil of E. leocoxylon.
