Terminalia chebula Retz., which was showed antimicrobial activity against intestinal pathogens through screening herbs related treatments of intestinal diseases, were extracted by methanol and fractionated by n-hexane, ethylether, ethylacetate,and water. Antimicrobial activities of the methanol extract and each fractionates were then investigated under the anaerobic broth system. The methanol extract showed antimicrobial activity against all intestinal pathogens(Eubacterium limosum ATCC 10825, Escherichia coli ATCC 25922 and Staphylococcus aureus KFCC 11764 hardly grew at 2,000$\mu$g/ml of concentration. Especially, Escherichia coli ATCC 25922 and Staphylococcus aureus KFCC 11764 hardly grew at 2,000$\mu$g/ml of concentration. There is no significant difference of antimicrobial activity among each fractionates. Fraction of Terminaliz chebula Retz. ethylacetate fractionate, which were fractionated by Sephadex G-200 and Silica gel column chromatography revealed the strongest antimicrobial activity at 12 to 21 and 22 to 34 of fraction number, respectively.
