【 摘 要 】

Water-distilled essential oils of wild and micropropagatedOriganum sipyleumL. (Lamiaceae), a herb native to Turkey, were analyzed by gas chromatography (GC) and gas chromatography/mass spectrometry(GC/MS). Eighteen components were characterized. In wild plants, the major constituent of aerial parts wasα-cadinol (23.41%), and of flowers, germacrene-D (20.13%). Thymol (48.55%) andα-cadinol (11.46%) were found as the major components in the micropropagated plants. The essential oils of wildO. sipyleumexhibited antimicrobial activity against all bacteria tested exceptPseudomonasaeruginosa,with minimum inhibitory concentration (MIC) values ranging from 500 to 1500 µg/ml. The antimicrobial activity of the essential oils of micropropagated plants was slightly lower than that of the essential oils of wild plants.
