ANTIOXIDANT ACTIVITY OF MORINGA OLEIFERA EXTRACTS
ABSTRACT: Moringa oleifera
have been evaluated for its antioxidant activity. M. oleifera leaves were
extracted with methanol, ethyl acetate, dichloromethane and n-hexane. The
antioxidant activity of extracts were evaluated by
1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging activity assay and
an improved 2,2’-azino-bis-[3-ethylbenzothiazoline sulphonate] (ABTS) radical
cation decolorization assay in vitro. Trolox was used as standard with IC50
5.89 μg/mL in DPPH assay and 3.06 μg/mL in ABTS assay. The methanol extract
showed the highest free radical scavenging activity with IC50 value of 49.30
μg/mL in DPPH assay and 11.73 μg/mL in ABTS assay. This study provided that M.
oleifera leaves possess antioxidant.
