Abstract:
This study aims to reveal the antibacterial activity and antioxidant capacity of selected local banana peels cultivated in Bali. In addition, total flavonoid and phenolic contents determination was done to investigate the correlation to their activity. Seven kinds of selected banana peels were used for this study. Extraction was conducted by maceration methods. Antibacterial activity assay was carried out by well difusion agar, while antioxidant capacity was conducted by DPPH reduction using galic acid as a standard. The content of total flavonoid and phenolic compounds was determined by Ultra Violet-visible (Uv-vis) Spectrophotometry.Antibacterial assay on selected banana peels against Staphylococcus aureusvaried between 11.00 and 14.77 and that of Escherichia colibetween 9.00 and 13.37 at concentration of 20% (b/v). Meanwhile, the antioxidant capacity of the peels have a rangefrom 3601.11 to 2523.71 mg GAEAC /kg extract.The antioxidant capacity and antibacterial activity were positively correlated with the total flavonoid and phenolic contents. Based on the study, it can be concluded that the banana peels can be used for infectious medicinesand have antioxidant properties. These findings suggest that flavonoid and phenolic content could be used as antibacterial and antioxidant agent.
