ABSTRACT
The aerial parts of Hedera nepalensis and Rubia manjith while root of Paeonia emodi were extracted in methanol-water (80:20) at room temperature. The crude extracts were screened against six bacterial strains i.e. Staphylococcus aureus, Staphylococcus methacilline, Escherichia coli, Pseudomonas aeruginosa, Salmonella typhi, Shigella flexenari and Pseudomonas sesame using agar well diffusion assay. P. emodi exhibited comparable results with standard drug. The maximum inhibition was shown against Salmonella typhi, Shigella flexenari (17 mm each). The extracts of H. nepalensis and R. manjith remained inactive against tested bacterial strains.
