The aim of the present study was to evaluate the effect of troxerutin (TXN) on Nickel (Ni) toxicity by using rats and in vitro model. Ni toxicity induced in male albino wistar rats (20 mg/kg body weight (b.w) was administered orally for 20 days). TXN was administered orally (100 mg/kg (b.w) for 20 days with administration of Ni. The toxic effect of Ni and the action of TXN was measure by determining the lipid peroxidation markers and antioxidant levels in plasma and various in vitro antioxidant systems. TXN exhibited a significant (p< 0.05) antioxidant activity in Ni induced toxicity by reversing the changes observed in TBARS, HP, Vitamin C, E and GSH. The free radical scavenging properties of TXN at different concentrations (10-50ug/ml) were investigated with various in vitro methods such as 2, 2’-diphenyl-1- picrylhydrazyl radical (DPPH), 2, 2’-azinobis (3-ethylbenzothiazoline-6-sulfonic acid) radical (ABTS•+), hydroxyl radical, superoxide anion scavenging activity and reducing power. Among the different concentrations, 50μg/mL of TXN was more effective compared to other concentrations in all in vitro assays. The above study conclude that TXN possesses potent in vivo and in vitro antioxidant activity with effective free radical scavenger for potential therapeutic value.
