ABSTRACT

In vitro evaluation of antibacterial activity of tubers (nutlets) of Cyperus esculentus L. against six bacterial species tested at 10, 20, 30, 40, 50, 60, 70, 80, 90 and 100 μl concentration in aqueous extract. Significant activity was observed in 70, 80, 90 and 100 μl concentration and recorded 28.0mm to 34.0mm inhibition. The Minimum Inhibitory Concentration (MIC) was also determined for all the species of bacteria. In four solvent extracts tested viz., methanol, ethanol, petroleum ether and chloroform extract, methanol and ethanol recorded a highly significant activity against all the test bacterial species tested at 500, 1000, 1500 and 2000ppm concentration and showed upto 33.0mm inhibition. All the result was compared to synthetic antibiotics Gentamicin (25mg), Tetracycline (25mg) and Streptomycin (25mg).
