摘要: 为研究羊栖菜多酚的提取工艺及其体外抗氧化活性,在单因素试验的基础上,以多酚浸出率为响应值,采用响应面法优化羊栖菜多酚提取工艺,并考察其对DPPH自由基、超氧阴离子自由基、羟自由基的清除能力以及总抗氧化能力。结果表明:在温度为70℃,乙醇浓度为40%,浸提时间46 min,液料比20:1,羊栖菜多酚的浸出率为4.048%;粗提液经XDA-7大孔树脂柱层析分离纯化其纯度为61.86%;羊栖菜多酚对DPPH自由基、超氧阴离子自由基、羟自由基清除作用的IC50分别为6.65、6000、125.42 μg/mL,总抗氧化能力为65.04 U/mg。该结果表明:羊栖菜多酚是一种极具开发潜力的天然抗氧化剂。

Abstract: To study extraction process of polyphenols from Sargassum fusiforme and its antioxidant activity in vitro, extraction conditions were optimized according to the polyphenols extraction rate by response surface methodology based on single factor experiment. Scavenging activity against DPPH, superoxide anion radicals, hydroxyl radicals and total antioxidant capacity of the extracts were evaluated. The results showed that extraction rate of polyphenols was 4.048% when the extracting time was 46 min, the temperature was 70℃,ethanol concentration was 40% and the ratio of liquid to material was 20:1. Crude extraction was purified by XDA-7 macroporous resin column and the content was 61.86%. The IC50 values of the obtained extracts against DPPH, superoxide anion radicals and hydroxyl radicals were 6.65, 6000 and 125.42 μg/mL. Total antioxidant capacity was 65.04 U/mg. These results suggested that polyphenols extracted from Sargassum fusiforme had great potential as a natural antioxidant.
