The aim of the study was to investigate and compare antibacterial and antifungal activity of leaves extract taken from four different plants Quisqualis indica Linn., Calotropis procera Ait., Achyranthes aspera Linn, and Ocimum sanctum Linn, against ten microorganisms comprising five bacteria (Bacillus subtilis, Enterobacter aerogenes, Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa) and five fungi (Alternaria porri, Aspergillus flavus, Aspergillus niger, Aspergillus oryzae, Penicillium chrysogenum) using well diffusion method. The in vitro study revealed that methanol extract was more effective than aqueous extract. Leaf extracts of Quisqualis indica Linn, and Achyranthes aspera Linn, were found to be more effective on fungal species and leaf extracts of Calotropis procera Ait. and Ocimum sanctum Linn, were found to be more effective on bacterial species.
