Antioxidant Activity of Leaf Extract of Aegle marmelos Correa ex Roxb.

Introduction: Leaf extracts of Aegle marmelos are reported to have hypoglycemic and anticancer effects. While a lot of information is available about the antioxidant activity of fruit of A. marmelos not much information is available about the antioxidant activity of the leaf of A. marmelos. Objective: The primary objective if this study was to ascertain the antioxidant activity of leaf extract of A. marmelos (AME). Methods: AME was evaluated for total phenolic content (TPC) and total flavonoid content (TFC) by Folin-Ciocalteau reagent method and by aluminium chloride method, respectively. Antioxidant activity of AME was assessed by FRAP assay, DPPH assay, ABTS cation scavenging activity and by reducing power determination. Results: High levels of TPC and TFC were found in AME which showed antioxidant activity comparable to vitamin C. Significant correlation between TPC, TFC and antioxidant activity of AME was found when Pearson’s correlation is applied. Conclusion: This study proved that the leaves of A. marmelos have high antioxidant component.
