Assessment of antioxidant capacity, proximate composition and inhibitory activity of unripe plantain (Musa paradisiaca) products on Fe2+ and sodium nitroprusside -induced oxidative stress in vitro

This study sought to assess the proximate composition, antioxidant and inhibitory effect of unripe false horn plantain (Musa paradisiaca) products on Fe2+ and sodium nitroprusside (SNP) induced lipid peroxidation in rat’s pancreas. The EC50 of Fe2+ chelating, 2,2-diphenyl-1picrylhydrazyl (DPPH) and OH free radical scavenging ability were also determined. A portion of the unripe false horn plantain...
