The ethanol extracts exhibited an effect by the DPPH assay, especially samples plant. HPLC analysis ethyl acetate identified presence phenolic acids flavonoids. showed activity against reference multidrug-resistant strains Staphylococcus aureus Enterococcus faecalis (MIC range 2000–250 μg/mL). hexane dichloromethane plant better Escherichia coli 250 125 μg/mL, respectively), but all less active Gram-negative species evaluated. results that L activity, even...
