| 摘 要： | 采用乙醇溶液提取并对花生多酚提取工艺和体外抗氧化活性进行了研究。选择浸提料液比、乙醇浓度、时间、温度4个因素进行实验,再经过正交实验,确定了花生多酚粗提的最佳工艺为：浸提料液比1：15、乙醇浓度67%、浸提时间1.5h、水浴温度70℃。体外抗氧化活性研究表明,花生多酚对DPPH自由基和羟基自由基有一定的清除能力。

| Abstract: | The extraction methods by alcohol and in vitro antioxidant activities of the peanut polyphenol were studied. The effectors, for example, solid-liquid ratio, temperature, extraction time and alcohol concentration, were chosen as single factor for the gradient experiments. The extraction conditions of polyphenol were further optimized by the orthogonal test. The results show that the optimum extraction is as follows： solid-liquid ratio is 1：15, extraction temperature is 70℃,extraction time is 1.5h, alcohol concentration is 67%. The results of the antioxidant activities show that the polyphenol can scavenge DPPH radical and hydroxyl radical. |
