以莲子皮为原料，采用响应面试验设计优化超声波辅助提取莲子外皮中总黄酮的工艺条件。在单因素试验基础上确定以乙醇体积分数、料液比、浸提时间和超声功率为影响因素，以总黄酮的得率为响应值，根据Box-Behnken中心组合方法采用4因素3水平响应值试验设计优化。超声辅助法提取莲子外皮总黄酮的最佳工艺条件为乙醇体积分数70%，料液比1∶50，浸提时间35 min，超声功率125 W，总黄酮得率14.48%，与预测值14.92%接近。该提取工艺模型可靠，拟合度较高。

The response surface methodology is used to optimize the ultrasonic-assisted extraction of total flavonoids from episperm of lotus seed. On the basis of single factor experiments, the ethanol/water solution, solid-to-liquid ratio, extraction time, and ultrasonic power on the extraction yield of flavonoids are effects. A regression model for the yield of flavonoids is established using a Box-Behnken design involving the above four factors at three levels. The optimal extraction conditions are as follows: the ethanol/water solution is 70%, solid-to-liquid ratio of 1∶50, extraction time of 35 min, and ultrasonic power is 125 W. Under these conditions, the extraction yield of flavonoids is 14.48%, closed to predicted yield of 14.92%. This model is reliable and optimal extraction conditions are highly efficient.
