Abstract

The aim of this work was to investigate the effect of grape stem bark extracts on Gram-positive, Gram-negative bacteria and a yeast strain and their antioxidant activity. Grapes are considered a rich source of polyphenolic compounds that show antioxidant and antimicrobial effects. The extracts were tested for their activity against clinically isolated Microbial strains using agar well diffusion method. The ethanolic extract showed highest activity followed by chloroform, while the petroleum ether extract showed the lowest activity at 100 mg mL-1 concentration. The inhibitory effect of extracts was compared with standard antibiotic ciprofloxacin and antifungal miconazole. Further, the chloroform and ethanol extracts at different concentration exhibited appreciable in vitro antioxidant activity
