摘要: 以荷兰菊苣为材料,采用高效液相色谱法测定菊苣酸的含量,建立菊苣酸提取工艺优化方法。通过单因素试验分析回流温度、甲醇体积分数、回流时间及料液比4个主要因素对菊苣酸提取量的影响,在单因素试验基础上采用L9(34)正交试验进一步优化菊苣中菊苣酸提取工艺条件。结果表明:菊苣中菊苣酸的最佳提取工艺为回流温度60℃、70%甲醇、料液比1:60(g/mL)、回流1h。在此条件下菊苣中菊苣酸提取量为8.808mg/g(干质量)。

Abstract: The purpose of this study was to optimize the extraction of cichoric acid from Cichorium lntybus L. by methanol reflux extraction and then establish an HPLC method for determining cichoric acid content in Cichorium lntybus L. One-factor-at-a-time experiments were conducted to understand the effects of reflux temperature, methanol concentration, extraction time and solid-to-liquid ratio on extraction efficiency of cichoric acid. Based on this, an L9 (34) orthogonal array design was employed to optimize extraction efficiency of cichoric acid. The results demonstrated that the optimal conditions for cichoric acid extraction were reflux temperature of 60 ℃, solid-to-liquid ratio of 1:60 (g/mL), methanol concentration of 70%, and reflux duration of 1 h. Under the optimal conditions, the extraction efficiency of cichoric acid was 8.808 mg/g dry basis.
