Abstract

Moringa oleifera played an important role in controlling oxidation caused by free radicals. Thus served as remedy to oxidative damages. This study was aimed to assess antioxidant activity and estimate total phenolic contents from different part of Moringa oleifera crude extract. Ferric-reducing antioxidant power assay was applied to evaluate antioxidant activity. Total phenolic compounds of the samples were measured using the Folin–Ciocalteu method. The reducing power of bark extract, revealed almost four times than any other part used, with (1499.67 ± 49.98 μM Fe (II)/g), followed by leaf with (432 ± 6.38 μM Fe (II)/g) and the lowest was seed extract having (126.67 ± 4.19 μM Fe (II)/g). The highest phenolic content was observed from methanolic bark (55.84 ± 2.92 mg GAE/g), followed by stem with bark extract having (48.81 ± 2.45 mg GAE/g), and the least was observed from stem extract with (42.25 ± 0.64 mg GAE/g). The result of this research showed that all the extract used are good source of natural antioxidant compounds. Therefore, Moringa oleifera can be utilized to cure oxidative related problems.
