摘要
考察影响微波法辅助提取赤豆总黄酮的主要因素,用正交实验确定了最优提取工艺,并通过清除超氧阴离子(O2-.)实验初步探讨了赤豆总黄酮的抗氧化活性。结果表明,微波辅助提取赤豆总黄酮的最优工艺为:微波时间20min,功率400W,35%乙醇,液料比25:1(mL/g),pH4。提取3次,总黄酮提取率为0.75%,此条件下提取到的赤豆黄酮具有较强的抗氧化活性。
The microwave extracting processing of total flavones in aduki bean was studied according to the orthogonal design, and the antioxidation of flavones was studied by the experiment of scavenging superoxide anion（O2-· ）.The optimal process of extraction of flavones from aduki bean with microwave were as follows： extracting time 20min, microwave power 400W, 35% ethanol, ratio of liquid to solid 25 ： 1 （ mL/g）, pH = 4. Three microwave extraction process, the extracting rate of total flavones was 0.75%, and the extraction had strong antioxidant activity.
