Abstract

Background: The present work aimed to find out the antibacterial activity of Nymphaea nouchali flower on human and plant pathogenic bacteria.

Methods: Antibacterial potency of methanol, acetone, ethyl acetate and petroleum spirit extracts of Nymphaea nouchali flower has been tested against four human pathogenic bacteria Bacillus subtilis (FO 3026) Escherichia coli (IFO 3007), Klebsiella pneumonia (ATTC 10031) and Sarcina lutea (IFO 3232) and one plant pathogenic bacterium Xanthomonas campestris (IAM 1671) by disc diffusion assay. Zone of inhibition produced by different extracts against the test bacteria was measured and compared with standard antibiotic disc.

Results: Methanol extract possessed better antibacterial activity against two pathogenic bacteria, B . subtilis (FO 3026) and S . lutea (IFO 3232) than commercial antibiotic nalidixic acid. Acetone extract showed moderate sensitivity whereas B . subtilis (FO 3026), S . lutea (IFO 3232) and X . campestris (IAM 1671) showed resistance to ethyl acetate and petroleum spirit extracts. The minimum inhibitory concentrations of various extracts were ranged between 128-2048 μgml-1 .

Conclusions: Nymphaea nouchali flower could be a potential candidate for future development of novel broad spectrum antibacterial herbal formulation.
