Preliminary evaluation of hepatoprotective potential of the polyherbal formulation

AIM: The aim of this study was to investigate the antioxidant and hepatoprotective effects of the polyherbal formulation (PHF)containing Cajanus cajan (L.)Millsp., Lawsonia inermis L. Linn, Mimosa pudica L., Uraria picta (Jacq.)DC. and Operculina turpethum (L.)Silva Manso on carbon tetrachloride (CCl(4))induced acute liver damage in albino rats. MATERIALS AND METHODS: The groups of animals were administered with PHF at the doses 100, 200 and 400 mg/kg b.w. (per oral [p.o.])once in a day for 7 days and at day 6th and 7th the animals were administrated with Carbon tetrachloride (1.0 mL/kg b.w. 50% v/v with olive oil,; p.o.). The effect of PHF on serum glutamine pyruvate transaminase (SGPT), serum glutamine oxaloacetate transaminase, alkaline phosphatase (ALP)and total bilirubin were determined in CCl(4) - induced hepatotoxicity in rats. Further, the effects of PHF on glutathione (GSH), superoxide dismutase (SOD)level and lipid peroxidation (LPO)activity were also investigated. RESULTS: The results demonstrated that PHF (400 mg/kg b.w.)significantly reduces the CCl(4) induced increase in level of serum SGPT, serum ALP and total bilirubin. PHF (400 mg/kg b.w.)prevents the depletion level of GSH and decrease in the activity of SOD in CCl(4) -induced liver injury in rats. In addition, PHF also showed a significant decrease in the LPO levels signifying the potent antioxidant activity. CONCLUSION: All our findings suggest that PHF could protect the liver cells from CCl(4) - induced liver damages and the mechanism may be through the anti-oxidative effect of PHF.
