Antimicrobial activity of the leaf and root extracts of Indigofera tinctoria Linn., Wrightia tinctoria Br. and Rungia repens Nees. against human pathogenic bacteria and fungi were evaluated. The ethanol extracts of these plants were evaluated for antimicrobial activity against human pathogenic bacteria such as Escherichia coli, Pseudomonas aeruginosa, Proteus mirabilis and pathogenic fungi such as Aspergillus niger, Aspergillus flavus and Aspergillus fumigatus. Ethanolic leaf and root extracts were prepared and based on the susceptibility of the test organisms were determined. It was found that ethanolic extracts showed high inhibition zone than control experiments.
