Abstract
The essential oil of the dried flowering aerial parts of Origanum vulgare L (Labiatae) collected from the suburb of Nour, Mazandaran
Province (North of Iran) was isolated by hydrodistillation and analyzed by means of GC and GC/MS. The major components of O.
vulgare oil were elemol (9.3%), sabinene (8.7%), -eudesmol (7.7%), terpinen-4-ol (7.6%), and -caryophyllene (6.7%). The O.
vulgare oil exhibited a pronounced antibacterial effect on some bacteria tested. The essential oil did not show antifungal activity.
