ABSTRACT

Aqueous and ethanol extracts of Aconitum heterophyllum on five test bacteria such as (Bacillus cereus, Escherichia coli, Klebsiella pneumoniae, Pseudomonas fluorescences and Staphylococcus faecalis) exhibited concentration dependent antibacterial activity. All fractions showed a promising activity towards Escherichia coli, Klebsiella pneumoniae, Pseudomonas fluorescences and Staphylococcus faecalis, however less inhibition was observed in Bacillus cereus. Similarly when compared to aqueous root extract, ethanol root extract showed maximum activity against all the tested organisms.
