Antimicrobial activities of mouthwashes obtained from various combinations of Elettaria cardamomum Maton., Lavandula angustifolia Mill. and Salvia triloba L. essential oils

Essential oils generally show significant antimicrobial activity.Herein,the aim was to obtained the volatileoils ofElettaria cardamomum Maton., Lavandula angustifolia Mill. and Salvia triloba L. and to investigate the antimicrobial activity of mouthwashes formulated with different combinations of E. cardamomum, L. angustifolia and S. triloba essential oils (v/v; 0.1/0.25/0.1; 0.2/0.25/0.1; 0.3/0.1/0.1 in 10 mL).The antimicrobial evaluation was performed using the disc diffusion method against the human pathogenic Staphylococcus aureus ATCC 6538, Escherichia coli NRLL B-3008,Bacillus cereus 14579, Salmonella typhiiclinical isolated. In the present study, among the tested bacteria, S. typhii was the more sensitive to the moutwash formulations, while B. Cereusand E. coli were the most resistant.
