Caesalpinia bonducella Flem. is traditionally employed to cure various disorders such as urinary disorders, diarrhoea, dysentery, leucorrhoea, piles, wounds, indolent ulcers, skin diseases, leprosy, and toothache. In the present study pod, seed coat and seed kernel of Caesalpinia bonducella were subjected to solvent extraction. The aqueous and ethanol extractswere subjected to antibacterial activity by disc diffusionmethod. Marked antibacterial activity was observed in case of both the extracts against test bacteria. Aqueous extracts were found to be inhibiting test bacteria to more extent than ethanol extracts. The results obtained justify the traditional use of the plant in folklore medicine. Further studies in animal models could reveal the potency of the plant in inhibiting pathogenic bacteria in vivo.
