The use of plant extracts with known antimicrobial properties can be of appreciable significance for therapeutic treatment. Presently, the research has been initiated to study the antibacterial activity of chloroform, and methanol extracts of Andrographis paniculata to emphasize the potential of herbal components in the field of medical science to kill various dreadful pathogens. The agar well diffusion method was followed to evaluate the antibacterial activity of leaf and stem extracts of A. paniculata against Bacillus subtilis, S. aureus, Enterococcus, P. aeruginosa, K. pneumonia and E. coli. The result revealed that all the doses of both extracts of A. paniculata potentially inhibited the growth of all the pathogens tested. Hence, the present investigation evaluates the potential anti bacterial activity of methanol extract of leaf and stem extract of A. paniculata.
