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

Abstract

<jats:title>Abstract</jats:title><jats:p>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: <jats:italic>Eucalyptus resinifera</jats:italic> Smith, <jats:italic>Eucalyptus tereticornis</jats:italic> Smith and <jats:italic>Corymbia maculata</jats:italic> (Hook.) K. D. Hill &amp; L. A. S. Johnson. The analyses were made by GC and GC–MS. The oil of <jats:italic>E. resinifera</jats:italic> was found to contain 1,8‐cineole (68.0%) as the major constituent. In contrast, the oil of <jats:italic>E. tereticornis</jats:italic> was found to contain 1,8‐cineole (23.2%) and <jats:italic>p</jats:italic>‐ cymene (13.8%), while that of <jats:italic>C. maculata</jats:italic> contained α‐pinene (49.7%), α‐eudesmol (18.0%) and β‐eudesmol (11.3%) as major constituents.
