  The presence study was carried out to investigate on the possible antibacterial activity of methanol (MECO) and chloroform (CECO) extracts of Corchorus olitorius (Senaung betina) using the in vitro disc diffusion methods. The sterilized blank discs (6 mm diameter) was impregnated with 20 μL of the respective extract (in the concentration of 10,000; 20,000; 40,000 and 50,000 ppm) and tested against Corneybacterium diphtheria, Staphylococcus aureus (ATCC 25923), Bacillus cereus, Proteus vulgaris, Staphylococcus epidermidis, Kosuria rhizophila, Shigella flexneri, Escherichia coli (O 157), Aeromonas hydrophila and Listeria monocytogenes. The MECO and CECO, at all concentrations, were effective against C. diptheria and K. rhozophila with the latter also effective against S. aureus and B. cereus. At the concentration of 40,000 ppm and above, the MECO was effective only against S. aureus, B. cereus and S. epidermidis while the CECO was effective against S. epidermidis, S. flexneri and A. hydrophila. Based on this study, it was concluded that C. olitorius possesses antibacterial activity that is comparable to some of the standard antibiotics.
