摘要: 通过单因素和旋转正交试验,对枸杞蜂花粉黄酮类化合物的超声波法提取工艺进行优化并建立数学回归模型。结果表明:影响枸杞蜂花粉黄酮类化合物提取的主次因素顺序为乙醇体积分数>料液比>提取时间;最佳工艺条件为乙醇体积分数75%、提取时间95min、液料比40:1(mL/g);测得枸杞蜂花粉总黄酮含量的平均值为3.03%(n=3),基本和预测值保持一致。

Abstract: On the basis of one-factor-at-a-time eperiments and central composite rotary design (CCRD) experiments, the ultrasonic extraction of flavonoids from wolfberry bee pollen was optimized and a mathematical regression model was contructed. Eththanol concentration was the most significant parameter that influences extraction efficiency, followed by material-to-liquid ratio; extraction time had the weakest influence. The optimal extraction conditions were ethanol concentration of 75%, extraction time of 95 min and material-to-liquid ratio of 1:40 (g/mL). Under these extraction conditions, the average experimental extraction yield of flavonoids was 3.03% (n = 3), which was consistent with the predicted result.
