摘要:

对高压-微波法提取花生根中白藜芦醇工艺进行研究,在单因素试验的基础上,通过二次旋转回归设计试验确定最佳提取工艺。结果表明:影响白藜芦醇提取率的各因素显著程度为乙醇体积分数>压力>保压时间>料液比;最佳提取条件为乙醇体积分数72%、料液比1:30(g/mL)、压力208MPa、保压时间4min、微波功率320W、微波时间90s,在此条件下白藜芦醇提取率为73.76%,为溶剂1次提取法(乙醇体积分数70%、料液比1:30、提取时间45min)的1.72倍。

Abstract:

The extraction of resveratrol from peanut roots by means of high pressure treatment followed by microwave
was optimized using response surface methodology based on a quadratic rotary regression design. Four factors in
decreasing order of their importance in influencing extraction efficiency were ethanol concentration, pressure,
pressure-holding time, solid/solvent ratio. The optimal conditions for resveratrol extraction were determined as 72%, 1:30 (g/mL),
208 MPa, 4 min, 320 W and 90 s for ethanol concentration, solid/solvent ratio, pressure, pressure-holding time,
microwave power and irradiation time, respectively. Under the optimized conditions, the yield of resveratrol was
73.76%, an 1.72-fold increase compared to the single solvent extraction using 70% ethanol as the extraction solvent
with a solid/solvent ratio 1:30 for 45 min.
