| 摘 要： | 研究萃取剂用量、温度、时间、ｐＨ值、酸化剂与甘草中甘草酸粗品提取率之间的关系。得出从甘草中提取甘草酸粗品的最佳提取条件为：蒸馏水为萃取剂，样品／萃取剂为１∶８，在９０℃提取，萃取时间２ｈ／次（共３次），Ｈ２ＳＯ４（３．５ｍｏｌ·Ｌ－１）作酸化剂，在此最佳提取条件下得到甘草酸粗品中甘草酸含量为６５％以上。

| Abstract: | This paper studied the relationship between extracting rate and its effects (extracting agent, temperature, time, pH value and acidulating agent)in the process of extracting rough Glycyrrhizic acid from Glycyrrhiza . The optimum extracting conditions were obtained: distilled water as extracting agent, sample/extracting agent is 1:8, extracting at 90℃ for 2h every time( 3 times), H 2SO 4(3.5mol·L-1)as acidulating agent. At conditions above, the content of Glycyrrhizic acid is 65% in the rough product obtained. |
