| 摘 要： | 以荞麦新芽蔬菜为研究对象,利用比色法和发光化学法测定了荞麦新芽蔬菜提取物对DPPH自由基、羟基自由基及超氧自由基的清除效果.结果表明,荞麦新芽蔬菜提取物对DPPH自由基、羟基自由基具有很强清除作用,而对超氧自由基的清除能力较弱.其清除DpPH的IC50值为0.064mg/mL,当荞麦新芽蔬菜乙醇提取物浓度为0.15mg/mL时,羟自由基清除率达57.65%.

| Abstract: | The effect to scavenge DPPH radical, hydroxyl radical and superoxidant radical by buckwheat sprouts extractive is determined by colorimetry and chemical luminescence method. The experiment shows that the buckwheat sprouts extractive possess powerful effect on scavenging DPPH radical and hydroxyl radical, yet weak on superoxidant radical. The IC50 value of scavenging DPPH radical is 0. 064mg/mL and the rate of scavenging hydroxyl radical is 57.65 % when the alcoholic extractive concentration of buckwheat sprouts was 0.15mg/mL. |
