Abstract

In the present investigation the effect of ethanol leaf extracts of Piper nigrum and Elettaria cardamomum against Urinary Tract Infection was studied, Hence the phytochemicals in the leaf extract was analyzed qualitatively and quantitatively. It was noticed that in both the extracts the concentration of flavanoids was present in higher concentration. Further from the UTI infected urine sample the organisms were isolated and confirmed to be E. coli using biochemical assay. The MIC of the leaf extracts against the isolated E. coli strains were identified to be 20000 μg/ml concentrations. In the Antimicrobial study both the leaf extracts at 20000 μg/ml showed highest zone of inhibition. In case of Pepper leaf extract the zone of inhibition was found to be 11 -18 mm and in Cardamom leaf extract the zone of inhibition was found to be 15-20 mm. Thus proving that the leaf extract had good antimicrobial activity.
