Reducing power of CPRME and its solvent fractions. All tests were performed in triplicates (n = 3). The statistical analysis of reducing power at the highest concentration of extract/fractions (1200 μg/mL) and standard (300 μg/mL) was performed. , # when compared with HF (the lowest reducing power). CPRME: Calotropis procera root bark methanol extract; HF: hexane fraction; DMF: dichloromethane fraction; EAF: ethyl acetate fraction; MF: methanol fraction; AF: aqueous fraction.
