Chemical and Biological Investigation of leaves of Eucalyptus Torelliana Essential oils from Benin

Abstract

The essential oil obtained by hydrodistillation from leaves of Eucalyptus torelliana F. Muell. (Myrtaceae) growing in Benin was analyzed by GC and GC/MS. Thirty eight components, which represented 99,6 % of the total constituents of the oil were identified. The essential oil is rich in hydrocarbons monoterpenic. The major constituents found were a-pinene (60.9 %), b- pinene (12.0 %), trans-b-caryophyllene (9.0 %), limonene (2.9 %) and aromadendrene (2.1 %). The oil extracted reveals an average antiradical and antimicrobial activities.
