USHIMARU, Priscila Ikeda et al. Antibacterial activity of medicinal plant extracts. Braz. J. Microbiol. [online]. 2007, vol.38, n.4, pp.717-719. ISSN 1678-4405. http://dx.doi.org/10.1590/S1517-83822007000400024.
The present study aimed at evaluating the in vitro antimicrobial activity of methanolic extracts of some medicinal plants against Escherichia coli, Salmonella Typhimurium, Staphylococcus aureus and Enterococcus sp. The methanolic extract of Caryophyllus aromaticus presented the highest anti-S. aureus activity and was effective against all bacterial strains tested.
