Study of essential oils of Eucalyptus resinifera Smith, E. tereticornis Smith and Corymbia maculata (Hook.) K. D. Hill & L. A. S. Johnson, grown in Cuba

The yields and chemical composition are reported of oils obtained by hydrodistillation from the leaves of three species grown in the western region of Cuba: Eucalyptus resinifera Smith, Eucalyptus tereticornis Smith and Corymbia maculata (Hook.) K. D. Hill & L. A. S. Johnson. The analyses were made by GC and GC–MS. The oil of E. resinifera was found to contain 1,8‐cineole (68.0%) as the major constituent. In contrast, the oil of E. tereticornis was found to contain 1,8‐cineole (23.2%) and p ‐ cymene (13.8%), while that of C. maculata contained α‐pinene (49.7%), α‐eudesmol (18.0%) and β‐eudesmol (11.3%) as major constituents.
