摘要
用连续提取装置一次性完成甘草酸提取过程 ,以 AB- 8大孔吸附树脂法分离甘草酸 ,最后用活性炭纯化。甘草酸收率较一般方法高 ,达 70 %～ 80 % ,纯度 90 %以上 。
Glycyrrhizic acid from licorice was entracted with continuous extraction device and was separated with macroporous absorbent AB-8. The crude product was purified with active charcoal to get a colorless or pale yellow product. The total yields range from 70% to 80% and purities are up to 90%. This facile method gives a higher yield than conventional ones.\;
