Study Of New Extracting Tuhnics Of Glycyrrhizic Acid

The article introduces the physical and chemical property of Glycyrrihizic acid in detail And paper mainly summarizes the domestic all extractions, and according to the lots of Glycyrrihizic acid Compared with all extractions, and according to the lots of exploring experiments ,we find out the optimum extracting method is soxhlex extraction ,and improves technological process with reducing its operation process ,the methods gets convenient ,declines the cost and the percent of the extraction will be the highest. Let it fit for the produce of industry.The product percent of the extraction is the object of the research. We choose the melting agent,the extracting time the ratio of the extracting and the Glycyrrihizic size as the factors of the research, and we design the ofthogonal array experiment, and we find out the best conditions for the producing. we make the Qualitative analysis by use of the chemical method and IR We make the Quantitative analysis by use of UV and weight determination method Let the rate of the product improves.We wish that the paper which we have been accomplished on Glyrrihizic acid could supply plenty of foundation for the extraction.
