Chemical composition and antifungal activity of essential oil of Salvia sclarea L. from Bulgaria against clinical isolates of Candida species

Abstract

The essential oil of Salvia sclarea L., growing in Bulgaria, was analyzed by gas chromatography – mass spectrometry. A total of 52 different compounds were identified, representing 98.25% of total oil content. Linalyl acetate (56.88%) and linalool (20.75%) were determined as major essential oil constituents, followed by germacrene D (5.08%) and β-cariophyllene (3.41%). Antifungal activities of clary sage essential oil and major compounds linalyl acetate and linalool against 30 clinical isolates, belonging to species Candida albicans, Candida tropicalis, Candida krusei, Candida glabrata and Candida parapsilosis were evaluated. Essential oil characterized with stronger anticandidial activity in comparison with pure compounds.
