摘要
研究了微波辅助提取花生壳中总黄酮的工艺条件,考察了乙醇浓度、料液比、微波时间、微波温度、微波功率对总黄酮提取率的影响,通过正交试验优化了提取工艺。结果表明最佳工艺条件为:乙醇浓度80%、料液比1:18、微波时间6min、微波温度70℃、微波功率500W,在此条件下,总黄酮提取率可达10.660mg/g。
The microwave-assisted extraction technologig of the flavonoids from peanut hull was studied,investigating the influences of ethanol concentration,ratio of liquor,microwave time,microwave power and microwave temperature on the flavonoids＇ extraction rate.The technological conditions were optimized through orthogonal test.The results showed that the optimum conditions were as follows： ethanol concentration 80%,ratio of material to liquor 1：18,microwave time 6 min,microwave temperature 70℃,microwave power 500W.The extraction rate reached to 10.660mg/g in the optimum conditions.
