A. Ravikumar and K. M. Subbu Rathinam

Hexane/acetone extracts of peltophorum pterocarpum colvillea racemosa and bauhinia purpurea of family Caesalpiniaceae were analyzed for antibacterial activity against eight selected clinical isolates. S. aureus, S. epidermidis, P. aeuriginosa, K. pneumoniae, B. subtilis, S. marcescens, E. coli and P. fluorescens. Among the three plants, hexane extract of P. pterocarpum extract showed maximum inhibition against organism K. pneumoniae of 225 μg/mL concentration and minimum zone of inhibition was observed in acetone extracts of C. racemosa and B. purpurea of 75 μg/mL concentration against organism E. coli, respectively.
