【摘要】 研究了普那菊苣中总酚的最佳提取工艺条件。在单因素试验的基础上,用正交试验法对总酚的提取工艺进行优选,选用L9(34)进行正交试验,以总酚含量为指标,考察提取温度、提取时间以及料液比对总酚提取的影响。得到的最佳工艺条件为:以水为提取溶剂,温度80℃,时间2 h,料液比(质量∶体积)1∶15,提取2次。更多还原

【Abstract】 The optimum process of extracting phenols,the bioactive component in chicory（Cichorium intybus cv.Puna） was studied and optimized with orthogonal test.Experiments were made by using L₉（3⁴） orthogonal design with extractive yield of phenols as the index,investigating the influence of temperature,extracting time and the ratio of solid to liquid.Optimum extraction conditions were determined as follows:H₂O as extracting solvent,temperature 80℃,time 2h,stock ratio 1∶15（mass volume）,extracting for two times.更多还原
