Antibacterial activity of fractions and isolates of Maytenus guianensis Klotzsch ex Reissek (Celastraceae) Chichuá Amazon

This aim of this study was to evaluate the antibacterial activity of fractions and isolates of Maytenus guianensis, a plant species used in Amazonian folk medicine. A disk diffusion technique was used to investigate the antibacterial potential. The hexanic fractions and tingenone B isolate showed inhibitory effects against Staphylococcus aureus and Streptococcus pneumoniae. These results indicate the antibacterial potential of this species and will enable future studies to identify novel therapeutic alternatives from this species.
