Inhibitory Effect of Rhizomes Methanolic Extracts of Rheum ribes and Tio2 NPs on Escherichia coli
Keywords:
E.coli, Rheum ribes, TiO2 NPs.Abstract
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
