Rheum ribes is a traditional medicinal plant found in mountainous areas in northern Iraq, also present in Syria, Turkey and rarely in east Iran, was it used to treat various ailments. This study was aimed to investigate the effect of rhizomes methanolic extract of Rheum ribes rhizomes and Titanium dioxide nanoparticles (TiO2 NPs) against uropathogenic E.coli. The identification of chemical compounds was made by using GC-MS. Furthermore, the antibacterial effect of Rheum extract and TiO2 NPs was evaluated using well diffusion method. The results showed that Nine compounds were identified using GC-MS method and also Rheum extract was effective against bacterial isolates and the best effect in concentration 5000 μg/ml for all isolates (the inhibition zone 24 mm).TiO2 NPs showed good activity against bacterial isolates when it were soluted in D.W and in ethanol, so it can be concluded that they may act as antibacterial agents in the future.
