Abstract: Lagenandra ovata (Linn.) Thw. syn. L. toxicaria Dalz. of Araceae family was evaluated for antibacterial activity against the Gram positive bacterium, Staphylococcus aureus and the Gram negative bacteria, Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, P. vulgaris and Pseudomonas aeruginosa.  Methanol extract of the rhizome and the oil fractions obtained from the methanol extract through column chromatography were screened.  The rhizome oil was found to be active against the pathogens, Staphylococcus aureus, Escherichia coli and Klebsiella pneumoniae and this activity was compared to the standard antibiotic, Chloramphenicol.  The rhizome oil of L. ovata possesses potential antibacterial activity and can be exploited as an antiseptic agent against the susceptible organisms.
