Abstract:

The flavonoids was extracted from cauliflower by using ultrasonicassisted solvent  and the response surface methodology was used to optimize the extraction conditions. Firstly, the effects of different extraction factors (ethanol concentration, liquidmaterial ratio, ultrasonic power, ultrasonic time, bath temperature, bath time and extraction times) on flavonoids yield were studied. And then, Box-Behnken response surface optimization test was carried on the basic of singer factor test result. The optimal conditions were as follows: 65% ethanol, liquid-solid ratio 32∶1 mL/g, ultrasonic power 30 W, ultrasonic time 5 min, bath temperature 50 ℃, bath time 40 min, and extraction time 1. Under this optimum conditions, the actual yield of flavonoids was 1.974 5 mg/g, and it was very close to the prediction value.

摘要: 采用超声波辅助溶剂浸提法提取白花菜中的黄酮化合物,通过响应面法优化最佳提取条件。考察单因素(乙醇体积分数、液固比、超声功率、超声时间、水浴温度、水浴时间和提取次数)对白花菜黄酮得率的影响,在此基础上,进行Box-Behnken响应面优化试验,分析并确定了最佳提取条件:乙醇体积分数65%、液固比(mL/g)32∶1、超声功率30W、超声时间5min、水浴温度50℃、水浴时间40min、提取次数1次。在最佳提取条件下,白花菜黄酮的实际得率为1.9745mg/g,与预期值十分接近。
