Abstract
Antioxidant potential of aqueous extract of the aerial parts of Bubonium gravelence was evaluated using superoxide and 1, 1-diphenyl, 2-picryl hydrazyl (DPPH) radical scavenging, phosphomolybdenum, reducing power and cyclic voltammetry. In DPPH radical scavenging activity, the IC50 value of the aqueous extract was found to be 0.152±0.05 mg/mL. In the phosphomolybdenum and reducing power tests, the extract has an activity in the order of 19 ± 0.45 and 47.42 expressed as μg of ascorbic acid equivalents per mg of extract, respectively. Moreover, the aqueous extract of Bubonium graveolens showed an antioxidant activity of the radical reduction O2•- in the order of 65.11 ± 1.4 at 1 mg / mL doses, The cyclic voltammetry of the Bubonium graveolens aqueous extract indicates one oxidation irreversible peak at 430 mV/(Ag/AgCl).
