| 摘 要： | 以连云港花果山野生马兰头地上部分为原料,研究马兰头黄酮的提取工艺。在单因素试验基础上,根据Box-Behnken试验设计原理,选取提取温度、提取时间、液料比和乙醇体积分数四因素三水平进行中心组合试验,建立黄酮提取率的二次回归方程,确定提取工艺的优化组合条件。结果表明:提取工艺条件为提取温度71℃、提取时间105min、液料比26.5:1(mL/g)、乙醇体积分数63%,黄酮提取率达到最大值。该条件下黄酮提取率预测值为1.65%,验证值为1.62%。

| Abstract: | The extraction of total flavonoids from the aboveground parts of Kalimeris indica L.wildly grown in Huaguoshan Mountain,Lianyungang was optimized.Based on one-factor-at-a-time experiments,a 4-variable,3-level central composite design was carried out to establish a quadratic regression model for the extraction efficiency of total flavonoids as a function of temperature,time,liquid-to-solid ratio and ethanol concentration.The model was analyzed by response surface methodology to find optimal conditions for th... |
