TRAPA NATANS AS GREEN DRUG TO PATHOGENIC ESCHERICHIA COLI

Abstract

Trapa natans is a medicinal plant and is used for the screening of antimicrobial property. T. natans seed was extracted in different solvents like ethanol, methanol, butanol and water. The antimicrobial activities of all the extracts were determined by agar well diffusion method. The antimicrobial activity was checked against pathogenic strain of E. coli. The inhibitory effect of extracts was compared with the standard antibiotic tetracycline. The physiochemical tests were done to check secondary metabolites which were present in different solvent extracts. TLC was carried out to separate secondary metabolites and further analyzed by different solvents. DPPH assay was conducted to confirm the antioxidant property of solvent extracts at different concentrations.
