Résumé
The chemical composition of the essential oil of Eucalyptus urophylla S. T. Blake, E. grandis Hill ex Maiden and a hybrid between the two species was examined by GC/MS. Although 43 compounds were characterized in the oil, three types of E. urophylla oil and three types of E. grandis oil were identified. The hybrid oil was found to be an intermediate between the 1, 8-cineole-rich E. urophylla and the p-cymene/α-pinene-rich E. grandis based on the occurrence of characteristic components of both species.
