通过单因素试验分别考察乙醇体积分数、提取时间、料液比、提取温度4个因素对菱角壳总黄酮得率的影响,确定各因素的最佳水平。利用SAS 8.1软件中心组合设计法设计响应面试验,通过方差分析回归建立数学模型,确定菱角壳总黄酮提取的最佳工艺条件。结果表明,最佳工艺条件为提取时间30 min,料液比1∶30（g∶m L）,乙醇体积分数50%,提取温度60℃,菱角壳总黄酮得率理论值为2.99%。通过验证试验确定,菱角壳总黄酮得率为3.08%,比理论预测值高3.01%。

A series of single-factor experiments are made to investigate the effects of ethanol concentration,extraction duration and temperature,liquid-to-solid ratio and the of the raw material on flavnonoids yield. Bases on this,by the Design-expert software according to the central composite design principle and experimental data obtained are subjected to quadratic regression analysis to create a mathematical model describing flavnonoids extraction. Detemine the optimum process condition of water chestnut hull flavonoids extraction. Results show that ...
