摘要
在单因素实验基础上结合Box-Behnken中心组合实验设计对麦冬果皮中原花青素的提取工艺条件进行优化研究,确定了提取工艺的最佳条件为乙醇体积分数:40.0%,超声波功率:810.6 W,提取时间:14.7 min,料液比:1∶30 g/m L。在此条件下麦冬果皮中原花青素提取率理论值为4.93%,实测值为4.95%。
Based on the results of single-factor-at-a-time-technique ,a three-level Box-Behnkenfactorial design was employed to optimizethe extraction condition of Ophiopogon Japonicus procyanidine .Canonical analysis was applied to estimate that a maximal extraction rate of procyanidine 4.93%could be obtained .The extraction conditions,such as solid-liquid ratio ,extraction time, ultrasonic power and the concentration of ethanol was 1∶30 （g/mL）,14.7 min,810.6 W and 40.0%respectively.These predicted values were also verified by validation experiments.
