ABSTRACT
The antibacterial activity of Tephrosia hookeriana leaf extract was tested against pathogenic bacteria like Staphylococcus aureus, Aeromonas veronii, Klebsiella pneumoniae, Pseudomonas aeruginosa, and Salmonella typhi, at a dose of 500μg by using disc diffusion method. Various solvents such as methanol, acetone, petroleum ether, and aqueous were used for extracts. The results reveal that, methanol at a dose of 500μg has showed significant activity against. The methanol extract showed that maximum inhibitory activity against Pseudomonas aeruginos (13.67±0.33). The zone of inhibition was measured and compared with standard Kanamycin (10mg). However, in none of the above mentioned extracts the inhibition zone was not more than that found in standard i.e., Kanamycin. This is the first approach in this plant and there are no early reports found.
