在单因素试验的基础上,选定提取时间、液固比、超声波功率为自变量,以多酚得率为响应值,采用Box-Benhnken法设计3因素3水平的响应面分析试验优化超声波辅助提取豹皮樟多酚工艺。结果表明,回归模型拟合度高,最佳工艺条件为:5 g样品,提取时间22 min,液固比21:1( mL:g,下同),超声波功率300 W,在此条件下,豹皮樟多酚得率可达3.76%。

Based on single factor test,a 3-factor,3-level Box-Behnken experimental was adopted,including dependent variables ( extraction time,liquid-solid ratio and ultrasonic wave power ) and independent variable( polyphenol yield ). The optimum conditions of ultrasonic-assisted extraction technology for polyphenol from Litsea coreana were determined by using response surface method. The results showed that the regression model fitted well with experimental data. The optimum conditions were 5 g samples,extraction time 22 min,liquid-solid ratio 21:1,ultrasonic wave power 300 W. Under these conditions,the polyphenol yield was 3. 76%.
