Synthesis process for industrially producing daidzein

Abstract

The invention provides a synthesis process for industrially producing daidzein. The synthesis process of the invention has simple raw material and easy operation, can realize standard process flow. When the synthesis process is used in industrial production, the whole reaction condition is very moderate compared to other organic synthesis conditions, and the production process is finished only by using the conventional chemical equipment without requiring high temperature and high pressure, and the period is short. In the synthesis process, the yield of the daidzein is over 50%, the yield of the daidzein with purity of over 98% is over 60% and the purity is over 98%.

Description

technical field [0001] The invention relates to a synthesis process of daidzein. Background technique [0002] Daidzein, English name Daidzein, chemical name 7,4'-dihydroxy-isoflavone, CasNo.: 486-66-8, molecular formula C 15 h 10 o 4 , [0003] [0004] Molecular weight 254.24, physical characteristic parameters: white powder. Chemical characteristic parameters: soluble in methanol, ethanol, dimethylformamide, ethyl acetate and other organic solvents. Daidzein is one of the isoflavone compounds contained in soybean seeds. It is also contained in leguminous plants such as kudzu and alfalfa, so soybeans, kudzu, alfalfa and their processed foods, soybean products, and kudzu powder Products are used as food with rich nutritional value and feed for livestock. [0005] At present, daidzein can be extracted from plants, and can also be prepared by synthetic methods.
