Antimicrobial activities of these extracts were tested against test microorganisms. Consequently none of extract of leaf did not affect test microorganisms. Methanol and ethanol extracts obtained from root, stalk, and seed of Rheum ribes exhibited antimicrobial activity against test microorganisms at various rate. Furthermore, it was determinated that the most sensitive microorganisms among test microorganisms were Bacillus subtilis ATCC 6633 and Enterobacter aerogenes ATCC 13048. "
