摘　　要：以梁平柚白皮层为原料,采用超声波辅助提取,在单因素试验的基础上,应用Box-Behnken中心组合设计(BBD)和响应面分析方法(RSM),研究了时间、温度、功率和固液比对梁平柚果皮中柚皮苷提量的影响.结果表明:回归方程有统计学意义,决定系数R2=0.973 4,4种因素对柚皮苷提取量的影响程度由大到小依次为功率,固液比,时间,温度.其优化提取工艺条件为时间50min,温度60℃,固液比1∶41g/mL,功率640 W,甲醇体积分数80%,在此条件下柚皮苷为57.124 6mg/g,与模型预测值57.744 1mg/g相近.To determine the optimal ultrasonic extraction conditions for naringin from Liangping pomelo mesocarp,mesocarp as raw materials has been studied by means of ultrasonic extraction.One-factor-at-atime method and response surface analysis based on Box-Behnken design have been used to explore the effects of time,temperature,power and solid-liquid on the extraction content of naringin.The mathematical model is statistically significant and its determination coefficient（R2）is 0.973 4.Four factors affecting the extraction content of naringin are as follows：power〉solid-liquid ratio〉time〉temperature.The results show that the optimum extraction conditions are as follows：time 50 min,temperature 60 ℃,solidliquid ratio 1∶41g/mL,power 640 w,methanol concentration 80%.Under the optimized conditions,the extraction content of naringin was 57.124 6mg/g and in good agreement with the predicted value 57.744 1mg/g.
