摘　　要：以软枣猕猴桃茎皮为原料,利用超声辅助提取的方法对原料中的槲皮素进行提取。采用单因素试验与响应面结合的方法来进行提取工艺优化。利用单因素试验优选出3个因素,即水浴温度、乙醇浓度、超声时间,以3因素为自变量,软枣猕猴桃茎皮中槲皮素提取量为因变量,进行响应面试验。结果表明,提取软枣猕猴桃茎皮中槲皮素的最优工艺为:超声时间20min、乙醇浓度为62%、水浴温度75℃,槲皮素提取量为1.0499 mg/g。The experiment was aim to optimizing the method of extracting quercetin in the bark of Actinidia arguta.The ultrasonic-assisted extraction method had been used during the experiment and the data analysis was through single-factor method and response surface method.Using single factor experiments select the three factors experiment,including bath temperature,ethanol concentration,ultrasound time.The response value of the regression analysis was subject to the extraction ratio of quercetin.The experiment result had explored the optimum quercetin extraction process that drawing from the bark of Actinidia arguta.The specific parameter was that 20 min Ultrasound,62% ethanol concentration,75 ℃bath temperature.The final extraction ratio of quercetin in the experiment was 1.0499 mg/g,which was roughly in line with the model prediction.
