摘 要:以茅岩莓茶为原料,采用不同体积分数的乙醇水溶液提取其中的黄酮类化合物,并用单因素和正交实验,依次考察乙醇体积分数、料液比、浸提温度以及浸提时间对黄酮提取率的影响,确定优化工艺参数。结果表明,当乙醇体积分数80%,料液比1∶20,浸提温度80℃和浸提时间4 h时,黄酮类化合物的提取率最高。

Abstract:Ethanol solution of different volume fraction was adopted to extract flavonoid from Maoyan berry tea, a raw material used in this research. Single factor experiment and orthogonal experiment were combined to investigate the effects of different volume fraction of ethanol, solid-liquid ratio and temperature and time of extraction on the extraction efficiency of flavonoid to obtain the optimum process parameter. The results indicated that the extraction efficiency of flavonoid reached its highest level at the volume fraction of ethanol of 80%, solid-liquid ratio of 1∶20, extraction temperature of 80℃ and extraction time of 4 h.
