Ethanolic and methanolic salt stress callus extracts of Solanum melongena L. were tested for in vitro antimicrobial and free radical scavenging assayssuch as DPPH (1,1-diphenyl-2-picrylhydrazyl) and ABTS+(2,2'Azinobis (3-ethyl benzo-thizoline-6-sulfonic acid) . In both the extracts the zone of inhibition is higher in Escherichia coli, Klebsiella pneumonia, Staphylococcus aureusand Streptococcus pyogenesat 90 µl concentration against the control. The antifungal activity of these extracts also the zone of inhibition is higher at 90 µl concentration against the control. The DPPH activity of different concentration of solvent extracts (1 mg/ml to 5 mg/ml) along with standard ascorbic acid among the five different concentration (50 µg/ml to 250 µg/ml) of extracts tested, the higher percentage of inhibition was observed in 250 µg/ml of methanol extract followed by ethanolic extract against the standard ascorbic acid. In ABTS+ activity the absorbance was increased with the increasing concentrations of both methanolic and ethanolic callus extracts.
