ANTIBACTERIAL EFFICIENCY OF CYPERUS ESCULENTUS L. TUBERS (NUTLETS) AGAINST IMPORTANT SPECIES OF BACTERIA
Kiran.B*, Sakchi Bhushan, Lalitha.V and Raveesha.K.A
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).
Keywords: C. esculentus, antibacterial activity, bacteria, solvent extract, aqueous extract.
