| 摘 要： | 目的：利用响应面法对刺槐花黄酮类化合物的提取工艺进行优化。方法：在单因素试验的基础上，选择液料比、乙醇体积分数、微波时间为自变量，黄酮类化合物提取量为响应值，利用响应面分析法，研究各自变量交互作用及其对黄酮类化合物提取量的影响，模拟得到二次多项式回归方程的预测模型。结果：刺槐花黄酮类化合物的提取工艺为乙醇体积分数75%、液料比37:1(mL/g)、微波时间145s、提取两次。结论：在最佳工艺条件下黄酮类化合物提取量为8.63mg/g。

| Abstract: | The optimum conditions for the extraction of flavonoids from Robinia pseudoacacia L.flowers were determined using response surface methodology.On the basis of one-factor-at-a-time experiments,Box-Benhnken central composite design was applied to investigate the effects of three variables,namely alcohol concentration,liquid-to-solid ratio and microwave heating time on extraction yield of flavonoids.A regression model describing extraction yield of flavonoids as a function of these three variables was establis... |
