| Résumé : | The essential oils obtained by hydrodistillation of the fresh leaves and mature fruits of Pittosporum viridulum were analyzed by GC and GC/MS. Fifteen components comprising 85.4% of the leaf oil and twenty-six components comprising 94.5% of the fruit oil have been identified. The major components of the leaf oil were spathulenol (28.4%), caryophyllene oxide (17.6%), and α-cadinol (9.0%), whereas germacrene D (28.6%), α-cadinol (13.0%) and δ-cadinene (9.4%) were the major components in the fruit oil. The oils showed moderate antibacterial activity against the Gram-positive bacteria Staphylococcus aureus and Salmonella typhi. |
