Table 2. The reducing power of the extracts
increased with an increase in concentration; however, when
compared to both aqueous organic solvent extracts, water
extracts appear to be less effective on reducing power. From
the above findings the results are well correlated with the amount
of phenolic constituents, which are present in the respective
extracts. Thus, phenolics present in moringa leaf extracts are
good electron donors and could terminate the radical chain
reaction by converting free radicals to more stable products.
The various crude solvent extract concentrations at 7.5 mg
(containing 1.50-4.13 µg of ascorbic acid) exhibited a greater
