ABSTRACT

The in-vitro antibacterial potential of Amaranthus hybridus Linn. root extracts in petroleum ether, ethylacetate, ethanol and water respectively was screened against Escherichia coli, Bacillus subtilis and Staphylococcus aureus. The ethyl acetate root extract showed highest antibacterial activity against test strains Bacillus subtilis and Staphylococcus aureus while alcoholic extract showed more inhibition against Escherichia coli.
