Fritsch (Lamiaceae) was screened for its chemical composition as well as its possible antioxidant and antibacterial properties. According to the gas chromatography – flame ionization detector (GC-FID) and gas chromatography – mass spectrometry (GC-MS) analyses, twenty-six compounds were identified, representing approximately 99.0% of the chromatographic area. The major component present in the essential oil was pulegone (44.8%), other main constituents were piperitone oxide (14.5%), iso-menthone (9.3%) and limonene (8.0%). The oil was tested for the antioxidant activity in 2,2-diphenyl-1-picryl hydrazyl (DPPH) assay and showed a dose-dependent free radical scavenging activity with EC<sub>50</sub> value of 6.71 × 10<sup>4</sup> μg/ml. The antibacterial effect of the essential oil was tested against Gram-negative and Gram-positive bacteria. The essential oil of <em>M. thymifolia</em> showed antioxidant potential and antibacterial activity.</p> ER -
