Abstract

Barks of six plant barks were screened for potential antibacterial activity. In evaluating antibacterial activity both aqueous and methanolic solvents were used. The plants were Azardirchata indica A. Juss, Terminalia arjuna. (Roxb.ex DC.) Wt. & Arn, Mimosops elengi L., Morus alba L., Acacia leucophloea (Roxb.) Willd., and Terminalia chebula Retz.. Antibacterial activity was tested against 5 bacterial strains Escherichia coli, Bacillus subtilis, Pseudomonas florescence, Klebseilla pneumonia and Proteus vulgaris. Two methods, Agar disc diffusion and Agar ditch diffusion method were used to study the antibacterial activity of all these plant barks. P. vulgaris and K. pneumonia were the most resistant bacterial strains. B. subtilis showed strong activity against the tested bacterial strains. Therefore, this can be selected for further investigation to determine its therapeutic potential
