In the present study, Salvia fruticosa and Salvia aramiensis essential oils’ chemical composition was compared, and their in vitro antimicrobial activity was tested against Escherichia coli, Klebsiella pneumoniae, Bacillus subtilis, Staphylococcus aureus, Candida albicans and Candida parapsilosis. The major compounds of S. fruticosa oil were eucalyptol (29.04%) and camphor (21.32%). Major components of S. aramiensis essential oil were eucalyptol (59.51%) and β-pinene (20.03%). The antimicrobial activities of essential oils were investigated by using disc diffusion and spectrophotometric broth micro-dilution methods. The highest inhibition zone diameter of S. aramiensis was found at 10.2 mm against C. albicans while the low inhibition zones (IZ) were on E. coli and B. subtilis (0.1 mm). Whereas the highest IZs of S. fruticosa was 8.38 for C. parapsilosis, the lowest IZs were 0.1 mm for E. coli, K. pneumoniae and B. subtilis by disc diffusion method (P˂0.05). The Minimum Inhibitory Concentration (MIC) of S. aramiensis and S. fruticosa EOs ranged from 56.2 to 146 μg/mL for all pathogens (P˂0.05). As a result, the antimicrobial efficacy of S. aramiensis on S. aureus and C. parapsilosis was demonstrated for the first time in this study, furthermore, both essential oils were found to be more effective against studied fungi rather than bacteria.
