Antibacterial activity of aqueous and ethanol leaf extracts of Cadaba trifoliata was evaluated by cup plate method against bacterial strains such as Staphylococcus aureus, Bacillus subtilis, Acinetobacter, Enterobacter aerogenes, Erwinia and Escherichia coli. The ethanol extract of the leaves demonstrated a high degree of activity against all the tested bacterial strains except Erwinia and Acinetobacter, whereas the aqueous extract of the leaves showed moderate activity against E. coli, B. subtilis and Staph. aureus and Enterobacter aerogenes.
