<div dir="ltr" style="text-align: justify;"><strong>Background: </strong>The genus <em>lagochilus</em>, family Lamiaceae consists of 44 species, 33 of which grow in central Asia. Only one report on the analysis of essential oil of Lagochilus species has been published. <strong>Objective:</strong> Aim of this study is to determine the chemical composition and antimicrobial activities of the hydrodistilled oil of flower and leaves of <em>Lagochilus kotschyanus</em> Boiss. of Iranian origin for the first time. <strong>Methods:</strong> The essential oils obtained by hydrodistillation from the flower and leaves of <em>L. kotschyanus</em> were analyzed by GC and GC/MS. The antimicrobial activities were determined by measuring the growth inhibitory zones (well diffusion assay).<strong> Results:</strong> The major constituents of the flower and leaf oils appeared to be myrcene (28.2% and 36.6%), α-pinene (25.9% and 29.8%) and β-caryophyllene (10.3% and 9.4%), respectively. <strong>Conclusion:</strong> In <em>L. kotschyanus</em> we identified 34 components representing 95.2% and 18 constituents representing 96.3% of the flower and leaf oils, respectively. Both oils were rich in regard to monoterpene hydrocarbons (72.7% and 79.7%) respectively. The sesquiterpene fraction was relatively small, representing 19.4% and 14.1%, respectively. Antibacterial activity was measured using the growth inhibitory zones. It was found that oil from leaves and flowers of <em>L. kotschyanus</em>, and especially that of flowers, exhibited interesting antibacterial activity.</div>
