| 摘 要： | 为探讨酸荔枝核总黄酮的提取工艺及体外抗氧化作用.采用正交试验乙醇热浸的方法考察提取溶剂浓度、提取时间、料液比等因素对酸荔枝核总黄酮提取率的影响.结果以液固比20∶1,提取时间30min,乙醇体积百分数为95％vol这3个因素为最佳.酸荔枝核中总黄酮对DPPH和氧自由基这2种自由基有很好的清除作用以及还原能力.

| Abstract: | The best extraction conditions of total flavonoids from acid litchi seeds and its antioxidant activity in vitro were investigated.The orthogonal test was employed to evaluate the effects of three factors including ethanol concentration,extracttion time and materialsolvent ratio on the extraction yield.The optimum technology was as follows:materialsolvent ratio 20∶1,extracttion time 30min and the ethanol concentration 95％vol.Total flavonoids from acid litchi seeds have good scavenging effect and reducing power against DPPH and oxygen free radical. |
