摘要

Many plants are used in Brazil to treat common infections without any scientific evidence of efficacy. This study aimed to evaluate the antimicrobial activity of hydroalcoholic extract from leaves of Eugenia uniflora, Punica granatum and association between the extracts against Staphylococcus aureus. The antibacterial activities of extracts were determined by macrodilution techniques in BHI broth. The minimum inhibitory concentration (MIC90) was determined by measuring the optical density in the spectrophotometer and was defined as the lowest concentration of crude extract that produced a 90% reduction in visible growth compared with non inoculated broth. All concentrations of extracts and association of extracts from the leaves of the plants tested showed some inhibition of bacterial growth. However, only the combination of the extracts was obtained MIC90 (0.5 mg/mL). Inhibitory activity on bacterial growth of the association of the extract from leaves of P. granatum with E. uniflora was higher when compared with the inhibition of bacterial growth promoted by extracts alone, indicating a bacteriostatic synergistic effect between these two extracts.
