摘要
利用响应面法优化超声辅助提取刺葡萄酒渣中白藜芦醇的工艺条件。通过单因素试验选取80%乙醇为提取溶剂,选择超声温度、超声时间、料液比进行三因素三水平响应面回归分析,得出超声辅助提取白藜芦醇的最优工艺条件为:超声温度61℃,超声时间49 min,料液比1∶17(m∶V),该条件下白藜芦醇的提取率为191.53μg/g,且以反式白藜芦醇苷的形式存在。
The response surface methodology was used to optimize the ultrasonic-assisted extraction of resveratrol from V. didii. Foex fruit win residues. Based on single factor experiments, 80% ethanol was determined as extract solvent, and then the ultrasonic temperature, ultrasonic time and solid/solvent ratio were investigated through re sponse surface experiment. The optimum conditions were as fol- lows： ultrasonic temperature 61 ℃, ultrasonic time 49 rain, solid/ solvent ratio 1 ： 17（m ： V）. Under this conditions, the yield of res- veratrol was 191.53 μg/g, and mainly in the form of trans piceid.
