摘要 研究了桑叶黄酮在不同反应pH、温度、时间及浓度下对亚硝酸盐的清除作用及其体外抗氧化作用。结果显示:桑叶黄酮具有较强的清除亚硝酸盐能力,在浓度为0.2mg/mL时,其对亚硝酸盐的清除率最大可达到75.69%,该清除作用随着反应时间、温度及浓度的增加而增大,随pH增大而减小。桑叶黄酮对亚硝酸盐的清除作用与其抗氧化活性有一定相关性。 In this study,the effects of pH,temperature,reaction time and substrate concentration on the nitrite scavenging ability and antioxidant activity of mulberry leaf flavonoids in vitro are studied.The results show that mulberry leaf flavonoids have a strong ability to scavenge nitrite in vitro.The flavonoids could eliminate 75.69% of nitrite at 0.2 mg/mL.Its nitrite-scavenging ability increases with the increase of reaction time,temperature and substrate concentration,but decreases as pH increases.The eliminating nitrite activity of mulberry leaf flavonoids may be related with its antioxidant activity.
