Abstract :Artemisia L. taxa insert ignore into journalissuearticles values(A. absinthium L., A. arborescens L., A. campestris L., A. scoparia Waldst. & Kit., A. santonicum L., and A. vulgaris L.); naturally distributed through western and southwestern Turkey were chosen as experimental materials in this study. Essential oils of the aerial parts of these Artemisia species were isolated by hydrodistillation and analyzed by gas chromatography-mass spectrometry. The major components were identified as sabinene in A. absinthium insert ignore into journalissuearticles values(17.56%);, camphor in A. arborescens insert ignore into journalissuearticles values(33.39%);, 1,2-dehydro acenaphthylene in A. campestris and A. scoparia insert ignore into journalissuearticles values(20.71% and 11.80%, respectively);, and a-thujone in A. vulgaris and A. santonicum insert ignore into journalissuearticles values(56.13% and 39.46%, respectively);. Essential oils and methanolic extracts of the plants were tested for antimicrobial activity using the disk-diffusion method against 8 bacteria and 1 fungus. Staphylococcus aureus was the most sensitive bacteria to all of the essential oils. A. santonicum and A. scoparia were the most active plants against Candida albicans, with 35-mm and 40-mm diameter zones, respectively. Antioxidant capacities of the plants were also tested. The radical scavenging activity of A. scoparia extract insert ignore into journalissuearticles values(48.51%); and essential oil insert ignore into journalissuearticles values(80.08%);, the Trolox equivalent antioxidant capacity of A. campestris extract insert ignore into journalissuearticles values(10.76 ± 0.47);, and the a-tocopherol equivalent of A. absinthium extract insert ignore into journalissuearticles values(5.87 ± 0.17); were the highest results.
