Description

【Technical field】 [0001] The invention belongs to the technical field of traditional Chinese medicines, and in particular relates to a method for extracting licorice. 【Background technique】 [0002] In recent decades, the production of Chinese herbal medicine has achieved a certain degree of mechanization and semi-mechanization. Traditional Chinese medicine is often considered to have low content of active ingredients, many impurities, and unstable quality. Therefore, the use of traditional Chinese medicine is mostly based on experience and cannot be in line with modern medicine. To solve this problem, traditional Chinese medicine must take the road of extraction and purification. The extraction of traditional Chinese medicine includes many unit operations such as leaching, clarification, filtration and evaporation. [0003] The traditional Chinese medicine licorice is the dried root and rhizome of Glycyrrhiza uralensis Fisch., Glycyrrhiza inflata Bat. or Glycyrrhiza glabr...
