The chemical composition of the volatile constituent from flowering parts of Thymus revolutus C., an endemic plant of Turkey, were analysed by GC/MS. Twenty-two components were identified, and carvacrol was found as a predominant compound in the oil. Furthermore, the essential oil was tested against 11 bacteria and four fungi at different concentrations. Results showed that the oil exhibited a significant antibacterial and antifungal activity.
