Abstract

This work was carried out to evaluate the total phenolic content and antioxidant potential (2,2-di-phenyl-1-picrylhydrazyl [DPPH] and ferric reducing antioxidant power [FRAP] methods) of Bauhinia monandra through its organs (leaves, stems and roots). The results showed fluctuating contents with a dominance in the leaves of total phytophenols in the crude hydromethanolic and selective AcOEt extracts (57.344 ± 12.35 and 48.165 ± 4.77 mg EAG/g DM, respectively) and of total flavonoids in the AcOEt extract (100.588 ± 12.06 mg EQ/g DM). The evaluation of antioxidant activity shows that the AcOEt extract of the stems is the most active with a CR50 = 23.442 µg/ml (DPPH method) and 44.34 ± 0.1 µg EVc/100 g DM and 182394.94 ± 406.09 µg EFeSO4/g DM (FRAP method).

Key words: Bauhinia monandra, phytophenols, antioxidant activity.
