Propionibacterium acnes, Staphylococcus epidermidis and Staphylococcus aureus have been recognized as the bacteria that are involved in the inflammatory process of acne, while oxidants and antioxidants are involved in the repair of cutaneous tissue affected. In this study an evaluation was made of the antibacterial effect by the agar diffusion and broth dilution method, the cytoprotective and antioxidant effect on 3T3 dermic fibroblast cells, treated with hydrogen peroxide and the scavenging capacity of free radicals was determined by the 2, 2-diphenyl-l-picrylhydrazyl (DPPH) method as well as the Reducing Power of the ethanolic extracts of the leaves of the Machaerium floribundum. Minimal bactericidal concentrations (MBC) were obtained against Propionibacterium acnes and Staphylococcus aureus of 5 mg/mL and 2 mg/mL, respectively. A cytoprotective effect of 111% was observed over the cel...
