摘要: 研究野豌豆花色素的抗氧化性和抑菌性。结果表明:野豌豆花色素具有还原性,能有效清除系统中的O2-·和·OH,且清除效果与色素质量浓度正相关。在野豌豆花色素质量浓度为0.72mg/mL时,对O2-·和·OH的清除率分别可达到69.01%和66.27%。野豌豆花色素对3种供试菌生长的抑制效果不同:大肠杆菌>枯草芽孢杆菌>金黄色葡萄球菌,且质量浓度越大,抑菌性越强。

关键词: 野豌豆, 花色素, 抗氧化性, 抑菌性

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
