Evaluation studies of antimicrobial activity on the leaf extracts of Achyranthes aspera Linn

ABSTRACT

Disc diffusion method was employed to determine the effect of methanol, acetone and chloroform extracts of the dried leaves of Achyranthes aspera against Staphylococcus aureus, Streptococcus fecalis, Klebsiella pneumoniae, Proteus vulgaris, Escherichia coli, Pseudomonas aeruginosa and Candida albicans. The chloroform extract shown to exhibit maximum potency against E. coli and Pseudomonas aeruginosa. Methanol extract showed moderate potency against E. coli and Candida species. Acetone extract was less effective against most of the species used except Streptococcus fecalis. Among all the extracts tested, none of the extract was found to be effective against gram positive S. aureus and gram negative Proteus vulgaris
