Abstract
Abstract In the present study, the objective was to evaluate the antioxidant and antimicrtobial activities of methanolic extracts of different indigenous cultivars of garlic. The antioxidant activity of all the extracts was determined using two complementary methods, namely 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay and Hydrogen peroxide (H2O2) scavenging assay. All the cultivars exhibited antioxidant activity to different extent. Hazro cultivar indicated highest antioxidant activity both by DPPH assay and H2O2 scavenging assay as compared to other cultivars. Antimicrobial activity of the garlic extracts was also evaluated by using the agar dilution method against different microbial strains. The Chinese cultivar was most resistant to Streptococcus viridans and Pasteurella multocida while Desi cultivar was resistant against Escherichia coli and Clostridium septicum. Silver Skin cultivar was most resistant against Staphylococcus aureus.
