Background: The therapeutic effects of sev-eral plants used in traditional medicine, are usu-ally attributed to their antioxidant properties.Aim and objective: To evaluate the in-vitroantioxidant potential of herbal preparation acombination of four selected medicinal plants(HP-4) using different experimental models.Material and Methods: Polyphenols, fla-vonoids and flavonols concentrations and anti-oxidant activity of herbal preparation (HP-4)as compared to butylated hydroxyl toluene(BHT)and á- tocopherol in various experimen-tal models were evaluated. Results: The anti-oxidant activities of HP-4 were concentrationdependent in different experimental modelsand were comparable to activities of BHT andα- tocopherol. Conclusion: Polyherbal formu-lation of HP-4 is better than individual plantextracts.
