ANTIBACTERIAL ACTIVITY OF RICINUS COMMUNIS LEAF EXTRACTAbstract
Based on the scope given by traditional knowledge, present study was conducted. The aim of the present study was to evaluate the antibacterial activity of castor (Ricinus communis, Family: Euphorbiaceae) leaf extract using five bacteria; two Gram-positive bacteria (Bacillus subtilis and Staphylococcus aureus) and three Gram-negative bacteria (Escherichia coli, Proteus vulgaris, Pseudomonas aeruginosa). The concentrated ethanolic extract of the crude drug of concentration 5gm/ml was tested for antibacterial activity by determination of zone of inhibition. Gentamycin is used as standard. It was found that the concentrated extract of the Ricinus communis leaves showed a better antibacterial activity in comparison with the standard.
