ABSTRACT: The present investigation was carried out to evaluate the antimicrobial and antioxidant potential of ethanolic and methanoic leaf extract of Barleria buxifolia. The antimicrobial activity was tested against four bacteria and two fungal. Among the four different bacteria tested, in the case of Streptococcus pyogenes the zone of inhibition is higher (18 mm) in 60μg/ml in ethnolic and methanolic concentration. Antifungal actvity was tested against two stains, in this Candida albicans the zone of inhibition was higher in 60μg/ml concentration (09 mm). The extract was effective on all the four bacteria and two fungal. The higher percentage of activity in DPPH was observed in 1000μg/ml (61.72%) followed by 800μg/ml (49.27%). More absorbance (0.54) was observed in the concentration of 1000μg/ml followed by (0.43) absorbance in 800μg/ml in methanolic concentration of FRAP activity. Antioxidant activity and reducing power of solvent extracts was found to be dose dependent manner.

Key words: Antimicrobial, Antifungal, Antioxidant, Inhibition, Barleria buxifolia,
