Abstract

Red Okra (Abelmoschus esculentus Moench) is widely distributed in Indonesia and its antioxidant ability is unknown. This study was performed to evaluate the antioxidant activities of red okra pods extracts. The powder of red okra was extracted by reflux. The first extraction used n-hexane (three times). Ethyl acetate was used to extract the residue (three times). Then, the residue was extracted three times using ethanol. Antioxidant activities were tested using DPPH and FRAP assays. This study showed that ethanol extract showed the highest antioxidant activity, which had the lowest IC50 DPPH (39.8 µg/mL) and the highest FRAP (89.15 µmol Fe2+/g). The result of DPPH and FRAP methods indicates that ethanol extract of red okra pods is classified as a very strong antioxidant.

Keyphrases: antioxidant activity, antioxidant potential, dpph assay, frap assay, red okra pods
