摘要
探讨橡实壳中多酚的超声波提取工艺。以普鲁士蓝法测定多酚含量,采用响应面分析法优化工艺条件。结果表明,橡实壳中植物多酚提取的最佳工艺条件为:提取时间17.4 min,超声波功率325.6 W,料液比l:29(m:V),提取率预测值为10.76%,验证值为10.56%。
Ultrasonic preparation conditions for acom shuck polyphenol have been conducted for using response surface methodology and the polyphenols content was determined by Prussian Blue specIrophotometry.The results demonstrated that the optimum condition of preparation time,ultrasonic power and ratio of material to liquid for polyphenol ultrasonic preparation is 17.4 min,325.6 W and 1∶29（m∶V）,respectively.The predicted value and validated value for the ratio of preparation is 10.76% and 10.56%,respectively.
