Antioxidant Activity of Fruit Peel Waste Extracts

Abstract

This research aimed to determine the total antioxidant capacity of the ten fruits peel waste extract, namely palmyra palm (Borassus flabellifer), areca nut (Areca catechu), lanzones (Lansium parasiticum), plantain (Musa acuminata x balbisiana), kepok banana (Musa acuminata x balbisiana colla), peanuts (Arachis hypogaea L.), palm (Elaeis guineensis), soybeans (Glycine max L. (Merr)), and corn (Zea mays L.). The DPPH and ABTS methods were used for the antioxidant assay. The extraction was carried out by maceration using n-hexane, methanol (MeOH), ethyl acetate (EtOAc), and dichloromethane (DM) as solvents. The DPPH assay results showed that the active extracts were MeOH and EtOAc extracts of peanut hulls and EtOAc extract of palmyra palm peels with IC50 values of 42.24, 51.17, and 55.78 μg/mL, respectively. Meanwhile, in the ABTS assay, the MeOH and EtOAc extracts of peanut hulls and the EtOAc extract of palmyra palm peels showed good antioxidant activity with the IC50values of 23.15, 30.02, and 47.43 μg/mL, respectively. This research provides evidence of the potential use of fruit waste as the antioxidant source.
