In the present study the powdered pod material of Caesalpinia coriaria (Jacq) wild was extracted with water acetone methanol and hexane. The antibacterial activity assays of all the extracts against the important human pathogens like Salmonella Typhimuriun, Escherichia coli, Pseudomonas aeruginosa, Methicillin resistant Staphylococcus aureus, and Klebsiella pneumonia were carried by bore well method. Acetone method shows significant activity. Phytochemical and quantitative studies of pod material revealed that antibacterial activity is due to the presence of tannin fraction. The result suggests that Caesalpinia coriaria is a potential candidate plant for the management of organism for antibacterial activity. https://www.biotech-asia.org/vol8no2/antibacterial-activity-of-caesalpinia-coriaria/ Antibacterial activity; Caesalpinia coriaria
