Abstract

Background: Plant source antioxidant plays an important role in regulating free radicals from the body. So it prevents damage to cell which can be caused by free radicals. Objective: This study was carried out to determine in vitro antioxidant potential, total phenolic content and total flavonoid content in flower and seed of Moringa oleifera. Results: Antioxidant activity of the extract was analysed by DPPH radical scavenging assay. Methanolic flower extract shows high potential free radical scavenging activity with IC50 value of 425 μg/ml. compare to methanolic seed extract that showed no IC50 value. The highest phenolic and flavonoid contents were observed from methanolic flower extract which was 48.04±2.44mg/g GAE and 14.27±0.62mg/g QAE respectively. Conclusion: The result proves that Moringa oleifera is an excellent source of antioxidants that can be used to reduce the effect of oxidative damages.
