The essential oil from aerial parts of Ziziphora clinopodioids plant was extracted by hydro distillation with efficiency of 1.86% (w/w). The components were characterized by means of gas chromatography–mass spectrometry (GC/MS) using kovat's retention indices. Thirty-two components of the essential oil which composed 98.18% of the total oil were characterized. The major components were pulegone (61.67%), cis-caran-trans-2-ol (12.66%), 1, 8-cineole (10.23%) and 2-β-pinene (2.16%).
Key words: Ziziphora clinopodioides, essential oil, pulegone, (-) cis-caran-trans 2-ol, 1, 8-cineole, 2-β-pinene.
