Abstract:
INTRODUCTION: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. METHODS:A disk diffusion technique was used to investigate the antibacterial potential. RESULTS:The hexanic fractions and tingenone B isolate showed inhibitory effects against Staphylococcus aureus and Streptococcus pneumoniae. CONCLUSIONS:These results indicate the antibacterial potential of this species and will enable future studies to identify novel therapeutic alternatives from this species.
