In the present study, the leaf powder of Moringa oleifera Lam. was subjected to preliminary phytochemical and invitro antioxidant analysis. The freshly prepared plant leaf extract was subjected to preliminary phytochemical screening, which revealed the presence of alkaloids, tannins, saponins, flavonoids, glycosides, phenolic compounds, terpenoids and steroids. Reducing power, superoxide anion radical, nitric oxide radical and hydroxyl radical scavenging assays were carried out to evaluate the antioxidant potential of the methanolic leaf extract of this plant. The amounts of total phenolic and flavonoid compounds were also determined. The results of the study revealed that the leaf powder of Moringa oleifera Lam. can be considered as a potential source of various phytochemicals and natural antioxidants.
