葡萄多酚的抗氧化活性

Study on the Antioxidant Activities of Grape Polyphenols

本文对葡萄多酚抗氧化活性进行研究。结果表明,葡萄多酚对DPPH、超氧阴离子自由基、羟基自由基清除活性IC50值分别为:1.96μg/ml、7.50mg/ml、1.91mg/ml,同时,在实验条件下它可将油脂的酸败时间推迟1d。

The antioxidant activities of polyphenols from grape seed was studied. IC50 of grape polyphenols on scavenging DPPH radical, superoxide anion radical and hydroxyl radical were 1.9μg/ml, 7.50mg/ml, 1.9 lmg/ml respectively. It can also defer the oil oxidation about one day under the experiment conditions.
