In-vitro Antioxidant Potential of a Herbal Preparation Containing Four Selected Medicinal Plants

Background: The therapeutic effects of several plants used in traditional medicine, are usually attributed to their antioxidant properties. Aim and objective: To evaluate the in-vitro antioxidant potential of herbal preparation a combination of four selected medicinal plants (HP-4) using different experimental models. Material and Methods: Polyphenols, flavonoids and flavonols concentrations and anti- oxidant activity of herbal preparation (HP-4) as compared to butylated hydroxyl toluene (BHT) and a- tocopherol in various experimental models were evaluated. Results: The anti¬oxidant activities of HP-4 were concentration dependent in different experimental models and were comparable to activities of BHT and a- tocopherol. Conclusion: Polyherbal formulation of HP-4 is better than individual plant extracts
