从甘草中提取甘草酸和黄酮类化合物的研究

Study on Purification Process of Active Constitutent from Licotice-Root

采用超滤与大孔树脂吸附联合工艺路线提取甘草中的有效成分——甘草酸和黄酮类化合物。实验结果表明,该工艺不但使操作过程简化,而且提高了甘草酸的提取率。此外还优化了压力、温度、循环液流量、浓度等操作参数。

The separation process by ultrafiltration and the adsorption process by macroporous resin are used to purify the active constituent licorice acid and compound of flavone from Chinese herbal medicine licorice root. The process not only is simplified, but also the extraction rate is raised. In addition, the operating conditions such as pressure, temperature recirculation rate, and concentration have been optimized.
