| Abstract: | The extract technology of glycyrrhiza flavonoids from licorice was studied. According to the properties of flavonoids, in order to extract the valuable components efficiently, orthogonal experiments, verifiability experiments and compare experiments were adopted. The best conditions were as follows: 20g glycyrrhiza washing powder (glycyrrhiza acid has been extracted), 0.8g Ca(OH)_2,the ratio of solid and liquor is 20, pH 2.5 and 2 h. The extraction rate of flavonoids reached 2.56% with standard rutin solution by spectrophotometry. |
