Abstract: The antioxidant and antibacterial activity of pigments extracted from the flowers of Vicia sepium was investigated. The pigment extract had reducing power and scavenging activity against superoxide anion and hydroxyl radicals in a concentration-dependent fashion. At a concentration of 0.72 mg/mL, its scavenging rates against superoxide anion and hydroxyl radicals were 69.01% and 66.27%, respectively. Its antibacterial activity against different strains followed the decreasing order: E. coli, Bacillus subtilis and Staphyloccus aureus and was positively correlated with concentration.

Key words: Vicia sepium, pigment, antioxidant activity, antibacterial activity
