The current study envisioned to evaluate time related protective effect of quercetin, alpha lipoic acid and ascorbic acid on liver of mice against sub-acute exposure of zinc oxide (ZnO-NP) nanoparticle. Male Swiss albino mice (n=72) were randomly divided into eight groups (n=9, each group). G1 received saline solution 0.9%; G2 received quercetin (100 mg/kg b.w); G3 received alpha lipoic acid (100 mg/kg b.w); G4 received ascorbic acid (100 mg/kg b.w); G5 received ZnO-NPs (50 mg/kg b.w); G6 received ZnO-NPs with quercetin; G7 received ZnO-NPs with Alpha lipoic acid and G8 co-treated with ZnO-NPs and ascorbic acid for 21 consecutive days. Body weight, hepatosomatic index and plasma biochemical parameters (total protein, albumin, globulin, total cholesterol, triglycerides, high density lipoproteins, low density lipoprotein, aspartate aminotransferase, alanine transaminase, alkaline phosphatase & bilirubin) were estimated. ZnO showed significant increase in body weight and cause alterations in all biochemical parameters. Co-administration of quercetin (100 mg/kg b.w), alpha lipoic acid and ascorbic acid daily along with ZnONPs, significantly ameliorate the dramatic alteration in biochemical parameters and hepatocellular necrosis caused by ZnO nanoparticles. Brine shrimp larvae cytotoxicity assay of ZnO nanoparticles showed 0% mortality. Present study concluded that all three active ingredients showed hepatoprotective effects against nanoparticles induced time dependent toxicity.
