Schinus areira L popularly used by its antiseptic properties, antirheumatic, among others. The aim of this study was to evaluate the antibacterial activity of different extracts and to determine the concentration responsable for this effect. Pulverized dry leaves were employed, which they were submitted to different extraction methods: infusion, decoction, aqueous extract and simulated digested extract. The extracts were liofilized and 1:2 serial dilutions were tested from 40 g/l. The bacterial activity was tested using the hole plate diffusion method. The results were compared with the bacterial growth inhibition by concentrations of gentamicin. Results obtained showed that the infusion, decoction and aqueous extract exhibited activity against the Staphylococcus aureus growth. S. areira L possesses antibacterial activity and the different extraction methods modified the antibacterial effect. Future studies in the caracterización of the product (s) with antibacterial activity will contribute to a better scientific knowledge and rational use of plants used in popular medicine.
