Objective: Chinese medicine effective component research is one of the main content of the Chinese medicine foundation research, how to extract effective components efficiently from known or unknown, is the key to Chinese medicine effective component research, also is Chinese traditional medicine development and one of the key technologies in the study of traditional Chinese medicine modernization.Currently the biggest problems in the research of traditional Chinese medicine material basis is the lack of objective and quantitative criteria and quality, therefore, extraction, separation and purification main active ingredients of Chinese medicine, Chinese medicine at present stage is the core of basic research.This thesis work in traditional Chinese medicine licorice as the research object, study the extraction technology of glycyrrhizic acid in glycyrrhiza, looking for a high extraction efficiency, less energy consumption, fast and suitable for instrial proction the extraction technology of glycyrrhizic acidMethods: glycyrrhizic acid extraction rate as the index, using the orthogonal experiment method to extraction time, extraction temperature and microwave power on the influence of glycyrrhizic acid extraction yield.Results: according to the orthogonal experiment method and the influence of factors on extraction yield and extract the total time, at the same time, considering that the extraction rate of glycyrrhizic acid as high as possible and to extract the total time as short as possible, in order to improve the proction efficiency, save energy, rece the cost, can choose to use the best condition of extracting glycyrrhizic acid from licorice are as follows: microwave power 667 w, system temperature 50 ℃, the extracting time 40 min.To sum up, microwave assisted extraction of licorice glycyrrhizic acid has many characteristics, such as energy saving, high efficiency, low solvent consumption.
