The essential Oils obtained by water distillation from aerial parts of Achillea schischkinii Sosn. and Achillea aleppica DC. subsp. aleppica were analyzed by gas chromatography and gas chromatography/mass spectrometry. 1,8-Cineole (32.5 and 26.1%, respectively) was the main component in both oils. The oil of A. aleppica subsp. aleppica was also found to be rich in bisabolol and its derivates. When tested for their antimicrobial, antiinflammatory, and antinociceptive activities, the oil of A. aleppica subsp. aleppica showed significant antiinflammatory, anti nociceptive, and moderate antimicrobial activities.
