Investigation of the antioxidant potential and total phenolics of Bubonium gravelence aerial parts

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)
