Abstract: 
Essential oils from, Salvia officinalis L. (SO), Mentha sylvestris L. (MS), Casearia sylvestris Sw. (CS), Mentha piperita L. (MP), Ocimum micrantum Willd. (OM) and Mentha arvensis L. (MA), plants used in Brazilian popular medicine were extracted using method I, as described in the Brazilian Pharmacopoeia, in order to obtain the phytochemical profile and to evaluate their antimicrobial activity against the following microorganisms: Bacillus subtilis, Staphylococcus aureus, Micrococcus luteus, Escherichia coli, Serratia marcescens, Candida albicans and Aspergilus oryzae. Test was made by means of the disk-plaque diffusion test in liquid medium using 1% essential oil. In the disk-plaque diffusion test, all the essential oils exhibited activity against B. subtilis, but OM showed the greatest inhibition zone and was the only one to show activity against S. aureus. Samples of SO, MS, MP, OM and MA were active against M. luteus, E. coli and S. marcescens, while A. oryzae was sensitive to MS, MP, OM and MA. No sample, however, was active against C. albicans. In the liquid medium test, significant results were observed for OM and MA, which inhibited the growth of all microorganisms for 24 hours, and OM continued active against E. coli and A. oryzae until the last reading.
