The Bauhinia ungulata, Bauhinia variegata, and Bauhinia purpurea are commonly used in folk medicine. However, few studies have investigated its antimicrobial potential. This study evaluated the in vitro antibacterial effect of crude extracts from leaves of B. ungulata, B. variegata and B. purpurea, in addition to identifying the class of constituents. The evaluation of antimicrobial activity was determined using the Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) methods against American Type Collecti-on Culture (ATCC) strains of Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Enterobacter aerogenes and Klebsiella pneumoniae. All crude extracts showed similar phytochemical analysis with saponins and tannins and bac.. View more»
