In this study, chemical composition of the essential oil of Teucrium scordium was studied using capillary GC and GC/MS instruments. In addition, the antimicrobial and cytotoxic activities of the oil and methanol extract were evaluated by disc diffusion and MTT assays, respectively. Forty-three volatile components were identified from the oil of aerial parts, representing of 98.1% of total oil. The major constituents were trans-α-bergamotene (52.3%), (Z)-α-trans-bergamotol (18.1%), linalool (3.0%) and piperitenone oxide (2.9%). The best anti-bacterial activity was observed for the methanol extract against Staphylococcus epidermidis with ZI (19.0 ± 0.47) mm and also against Proteus mirabilis with MIC value of 1.25 µg/mL. Investigation of the samples on cell viability of HeLa cells showed a good activity for the essential oil with an IC50 value of 5.2 µg/mL. Our results indicated that T. scordium can be considered for further analyses as an effective and safe curing agent for cancer and pathogenic infection therapies.
