The present study was designed to evaluate the antioxidant activity and radioprotective effects of Naringin and Naringenin in γ-irradiated mice. The antioxidant activity of Naringin and Naringenin was evaluated by 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) and ferric reducing antioxidant power (FRAP) assays. Healthy female BALB/c mice were administered Naringin and Naringenin orally (90 μM/dose and 180 μM/dose) for 7 consecutive days prior to γ-irradiation (6 Gy). Naringenin displayed a much higher antioxidant activity in ABTS and FRAP than naringin. γ-irradiation resulted in cellular damage with decreased spleen and thymus indices and white blood cells (WBC) count. Additionally, γ-irradiation significantly increased lipid peroxidation and decreased the levels of antioxidant enzymes and glutathione (GSH) in the liver tissue. Strikingly, prior administration of Naringenin resulted in considerable prevention of these symptoms. Protection against γ-irradiation-induced cellular damage by Naringenin is likely due to its higher its antioxidant activity. Together, these results confirm that Naringenin is a potent antioxidant and radioprotector.
