摘要 以乳白香青为原料,确定乳白香青中绿原酸最佳提取的工艺条件。在单因素实验的基础上,运用Box-Behnken中心组合实验设计,建立绿原酸提取得率的二次回归模型,确定乳白香青中绿原酸的优化工艺条件为:提取温度为41℃,液料比为31∶1(mL/g),甲醇浓度为66%(v/v),绿原酸的得率为5.2796(mg/g),接近于模型预测值5.3295(mg/g)。 In order to promote the extractability of chlorogenic acid from Anaphalis lactea Maxim,we established a quadric regression equation for predicting the yield of chlorogenic acid on the basis of one-factor tests, according to Box-Behnken design . The result showed that the optimum conditions for the extraction of chlorogenic acid were as follows:extraction temperature 41℃ ,ratio of material to solvent 31∶1 (mL/g),Mthanol concentration 66%(v/v). Under these conditions,the chlorogenic acid yield was up to 5.2796 (mg/g) which was well matched with the predictive extracting yield 5.3295(mg/g).
