Abstract
The aerial parts of Salvia officinalis (Lamiaceae), have been used in Iranian traditional medicine. Composition of the essential oil, which was obtained from the aerial parts of Salvia officinalis collected from Ilam, was determined by gas chromatography. In total, 20 components (87.17 % of essential oil) were identified. Major constituents were α-pinene (4.32 %), camphene (3.0 %), β-pinene (9.11 %), 1,8-cineole (15.0 %), α-thujone (5.67 %), β-thujone (4.32 %), camphor (6.03 %), borneol (12.65 %), bornyl acetate (4.9 %), caryophyllene (3.65 %), γ-elemene (6.2 %) and β-selinene (3.42 %).
