Antibacterial Activity Of Spinach (Spinacia Oleracea)

ABSTRACT

Plants contain a wide range of natural drugs. Thus the present study investigated the effect of different solvent extracts of Spinacia oleracea on some test organisms. The well diffusion method was used in determining the antibacterial efficacy of plant extract against test organisms. Here two polar solvents namely ethanol and methanol were used. The Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) were evaluated for all solvent extracts of Spinacia oleracea against each pathogen that recorded antibacterial activity and found the significant bactericidal MIC ranged between 0.152 to 1.250 mg/ml and MBC ranged between 1.250 to 5.000mg/ml against test bacteria. These results predict that the polar solvent extract of this plant can be used as natural antibacterial agent to cure E. coli, S. aureus and Klebsiella pneumonia which are test organisms.
