The essential oil yield was<em> H. persicum </em>(2.5%); <em>Z. clinopodioides</em> (1.5%) and <em>N. asterotricha</em> (1.8%), respectively. Major component identificated in <em>H. persicum </em>were; trans-carveol 38.7%, α-terpineol 23.8% and isobornyl formate 9.2%, <em>Z. clinopodioides</em> were carvacrol 52.7%, linalool 15.9% and menthol 14% and <em>N. asterotricha</em> were terpinolene 21.2% , n-dodecanol 18.6% and n-undecane 12%, respectively. In <em>H. persicum </em>with trans-carveol (38.7%), which can use as stimulates central nervous system, allergenic, and in <em>Z. clinopodioides </em>with major compound carvacrol (52.7%), which can use as a Anesthetic, kills and expels worms, may help prevent alzheimer's disease, antiinflammatory, antioxidant, antiplaque, antiseptic, bactericide, relieves flatulence, relaxes intestines, expectorant, prostaglandin-inhibitor, relaxes trachea.
