摘要：通过单因素及响应面法对微波辅助提取五倍子单宁的工艺条件进行了优化,考察了液固比、微波提取时间、提取温度3个自变量对响应值单宁酸提取得率的影响。结果表明,单宁酸最佳微波辅助提取条件为:五倍子粉末10 g,微波功率600 W,液固比32:1(mL:g),提取时间7 min,提取温度62℃,在此条件下单宁酸提取得率为65.13%。
The microwave-assisted extraction process of tannic acid from Chinese gallnut were optimized using response surface method （RSM）. The effects of three independent variables, i.e. liquid to solid ratio, microwave extraction time and extraction temperature, on the yield of tannic acid, was also investigated. Results indicated that the optimum microwave-assisted extraction was obtained as the powder of Chinese gallnut 10 g, microwave power 600 W, liquid to solid ratio 32 ： 1 （mL： g）, ultrasonic extraction time 7 min and temperature 62℃, respectively. Under this optimum condition, the extraction yield of tannic acid was 65.13%.
