摘要
采用水提法从金莲花中提取黄酮。考察了浸泡时间、回流时间、固液比和温度四个单因素对黄酮提取率的影响,在此基础上,选择回流时间、固液比和温度三个因素水平进行正交实验。结果表明,当浸泡时间为1h、回流时间为1.5h、固液比为1:23.3和温度为100℃时,可得最大提取率为30.5l(wt.)%。
Water extracting method was used to extract flavone from trollius. The influences of four single factors of impregnation time, reflux time, ratio of solid to liquid and temperature on extraction effieiency of flavone, based on which, impregnation time, reflux time , ratio of solid to liquid and temperature were determined to be as the factors for orthogonal experiment. The results showed that the maximum extraction efficiency of flavone was 30.51% in weight when the impregnation time, reflux time, ratio of solid to liquid and temperature were 1h 、 1.5 h, 1 ： 23.3 and 100 ℃.
