Chemical composition of the essential oil from Ziziphora clinopodioids Lam. from Iran by means of gas chromatography-mass spectrometry (GC-MS)

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 chromatographymass 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%)
