Dr. T. Francis Xavier, G. Dhanasekaran* and D. Sathish Kumar

Abstract

Ethyl acetate, ethanol, acetone, chloroform and petroleum ether extracts of the dried tuber Amorphophallus campaulatus were tested for their antibacterial efficacy by the disc diffusion method against four grampositive bacterial species, viz., Staphylococcus haemolyticus, Staphylococcus lentus, Staphylococcus aureus and Bacillus cereus six gram-negative bacterial species viz., Escherichia coli, Serratia marcescens, Enterobacter amnigenus, Klebsiella pneumonia, Klebsiella oxytoca and Brevibacterium paucivorans. Among the various solvent extracts studied ethanol, acetone and chloroform tuber extracts showed a highest antibacterial activity followed by ethyl acetate and petroleum ether.

Keywords: Amorphophallus campanulatus, Antibacterial, Disc diffusion method.
