Abstract

The invention provides a soybean isoflavone and phosphatide compound and its preparing process, wherein the molar ratio of soybean isoflavone and phosphatide is 0.5-2 : 1. The preparing process consists of charging organic solvent with low dielectric constant into the mixture, stirring and mixing, filtering the solvent, finally subjecting the filter liquor to decompression drying or freeze drying.

Description

technical field [0001] The invention belongs to the field of medicine, in particular to a soybean isoflavone phospholipid compound and a preparation method thereof. Background technique [0002] Soybean isoflavones are mainly derived from leguminous plants, including soybean isoflavone glycosides and soybean isoflavone aglycones. The main components include genistein (Genistein), genistein (Genistin), daidzein (Daidzein), daidzein (Daidzin) and so on. Their structural formula is as follows: [0003] [0004] Compound name R 1 R 2 R 3 R 4 R 5 Daidzein H H OH OH H Genistein OH H OH OH H Glycitein H OCH 3 OH OH H Daidzin H H O-glucoside OH H Genistin H H O-glucoside OH H Glycitin H OCH 3 O-glucoside OH H [0005] Soy isoflavones h...
