Abstract:

The present study aims to determine antibacterial activity of acetone and methanol extracts from leaves and bark of Holarrhena antidysenterica. Agar well diffusion method was used for screening of extracts against six bacteria using different concentrations (25, 50, 75 and 100%) of extracts. Methanol and acetone extracts of both leaves and bark showed potent antibacterial activity against all six tested bacteria. Extracts prepared using methanol exhibited higher antibacterial activity as compared to its corresponding acetone extract. In general trend growth inhibition was found to be higher for S. aureus and B. Cereus followed by E. coli, L. monocytogenes, P. aeruginosa and Y. pestis. Bark extracts (methanol and acetone) were more active towards all the bacterial strains as compare to leaves extracts as only methanolic leaves extracts showed considerable inhibition zone.
