EssentiaJ oils composition and antibacterial activities of Eucalyptus camaldulensis Dehn.

摘要

Eucalyptus camaldulensis leaves were harvested from Caspian seashore and Ghalegardan regions in Mazandaran province of Iran and were dried. The essential oils were isolated by hydro-distillation and analyzed by GC-MS. Results showed that oxygenate-hydrocarbon compounds ratios (monoterpene oxygenate to monotepene hydrocarbon and sesquiterpene oxygenate to sesquiterpene hydrocarbon) were higher in the essential oil of Ghalegardan sample. The major components of Ghalegardan were eucalyptol (29.2%), a-phellanderene (17.43%), beta-pinene (7.1%), arommadenderene (alio) (5.75%), terpineol-4-ol (4.92%). In Seashore sample 36 compounds were identified, in which the major components were eucalyptol (46.74%), arommadenderene (alio) (12.1%), terpineol-4-ol (7.6%), P-pinene (6.35%). The essential oil of both the samples possessed antibacterial activity and it was more effective against Staphylococcus aureus than Escherichia coli. Also, antibacterial activity of Ghalegardan sample was slightly higher than Seashore sample.
