In vitro Antimicrobial Activity of Some Extracts of Salvia spp Harvested from the Oltenia Flora Using Different Solvents

In this study, the antimicrobial activity of three Salvia spp. (S. glutinosa, S. splendens, S. verticillata) extracts prepared with different solvents was assessed using the diffusion method and the quantification of the minimum inhibitory concentration for each extract on S. aureus, E. coli and C. albicans standard strains. The results showed that the extracts of the three Salvia spp. are suppressing the growth of the bacteria tested with variable potency. Among the different solvent extracts, n-butanolic extracts of all the three species of Salvia spp. revealed the most important antibacterial activity against S. aureus and E. coli. S. splendens extracts proved to be the most efficient on C. albicans regardless of the solvent used.
