    Abstract:
    In the present study the antioxidant capacity of Periploca hydaspidis was assessed through various in vitro assays and by the hepatoprotective potential on CCl4 induced toxicity in rat. Phytochemical analysis of different extracts of P. hydaspidis indicated existence of various phytochemical classes. HPLC-DAD analysis of methanol extract indicated the existence of rutin, gallic acid and caffeic acid. Total phenolic (TPC) and total flavonoid content (TFC) exhibited significant (p < 0.05) correlation with 1,1-diphenyl-2-picrylhydrazyl (DPPH), nitric oxide, hydroxyl ion, inhibition of β-carotene oxidation, iron chelation, reducing power and total antioxidant capacity. In hepatic sample of rat, CCl4 administration increased (p < 0.05) the level of nitrite, hydrogen peroxide (H2O2), thiobarbituric acid reactive substances (TBARS) whereas a decline was recorded in antioxidant enzymes; superoxide dismutase (SOD), peroxidase (POD), catalase (CAT) and in reduced glutathione (GSH). Concentration of alanine transaminase (ALT), alkaline phosphatase (ALP), aspartate transaminase (AST) and globulin increased (p < 0.05) whereas level of total protein and albumin decreased in serum of CCl4 treated rats. Level of pro-inflammatory cytokines; tumor necrosis factor-α (TNF-α), tumor growth factor-β1 (TGF-β1) and resistin was increased (p < 0.05) in serum whereby anti-inflammatory markers; interleukin-10 (IL-10), adiponectin and nuclear factor erythroid 2- related factor 2 (Nrf-2) decreased (p < 0.05) in hepatic tissues of CCl4 treated rats. DNA damages and histopathological alterations were induced with administration of CCl4 to rat. The altered levels of various parameters provoked by CCl4 toxicity restored towards the control level by the methanol extract of P. hydaspidis in a dose dependent manner. These results suggested the presence of antioxidant and anti-inflammatory phyto-constituents in methanol extract of P. hydaspidis.
