Abstract

Recent studies indicated that regular consumption of antioxidant-rich foods reduces cellular oxidative stress and protects against health-related problems. This study aimed to assess the in vitro antioxidant properties of the papaya epicarp extract against hydrogen peroxide (H ₂O ₂)-induced oxidative stress in human SH-SY5Y neuronal cells. Our study revealed that papaya epicarp extract acted as a potent free radical scavenger and provided neuroprotection against H ₂O ₂-induced oxidative stress. Papaya epicarp extract ameliorated glutathione depletion, restored total antioxidant capacity and augmented the inhibition of antioxidant enzymes (catalase, glutathione peroxidases and superoxide dismutase). In conclusion, papaya epicarp extract can be used as a functional dietary ingredient that might help in reducing the neurological health problems associated with various oxidative stress insults.
