Various extracts of Entada abyssinica stem/root bark have been shown to have antimicrobial activity using organisms : Staphylococcus aureus, S. epidermidis, Escherichia coli, Pseudomonas aeruginosa, Bacillus megaterium, Candida albicans, Aspergillus niger and Tricophyton mentagrophytes on solid media. Chromatographic analysis of the bark extracts of different trees (according to age), showed them to contain in common the components responsible for the observed antimicrobial activity with differences observed in minor bands not of antimicrobial importance.
