Embodiment

[0049] 1. Dry 1Kg of mature whole soybean cake powder, extract 2 times with 60% ethanol aqueous solution, each time for 2 hours, concentrate after filtering the extract, remove ethanol to obtain a concentrated solution. The concentrated solution was degreased with petroleum ether, and the aqueous layer was concentrated again and dried in vacuo to obtain 87 g of dry powder. The dry powder was dissolved in water, passed through a macroporous adsorption resin column, and then eluted with alcohol water. After the eluate was concentrated, it was dried in vacuum to obtain 24 g of dry powder. 24g of dry powder was mixed with sample for alumina column chromatography, eluted with a mixed solvent of chloroform and methanol, the eluent was concentrated, and dried in vacuo to obtain 15g of dry powder, mixed with silica gel, chromatographed on a silica gel column, eluted with a mixed solvent of chloroform and methanol, and eluted with The solution was concentrated and vacuum-dried to obtai...

Abstract

The present invention relates to a Soy daidzin composition and its preparation method and application. It provides three compounds containing isoflavone glucoside which can be used for preparing medicine for curing climacteric syndrome due to female hormone deficiency and middle-aged and senile obtiterating angiocardiopathy and cerebrovascular disease. Said composition contains isoflavone glucoside compound, i.e. diadzin, soyabean flaving glucoside and genistin, and three kinds of isoflavone are 90%-100% of the composition, and the ratio of three isoflavone glucoside is 2-3:1-2:3-4. It can be made into various dosage forms of medicine preparation, and its preparation method includes the following steps: extracting soyabean with ethyl alcohol, concentrating, extracting with petroleum ether, vacuum drying to obtain dried powder.

Description

Technical field: [0001] The invention relates to the technical field of medicine, in particular it is a soybean isoflavone glycoside composition and its preparation method and application. Background technique: [0002] Soybean isoflavone glycosides are isoflavones extracted from soybeans. Soybean is the mature seed of Glycine max (L.) Merr., a leguminous plant, and it is one of the main food varieties in my country and many countries and regions in the world. As a functional food, soybean and its medicinal value were first recorded in "Shen Nong's Materia Medica" in 2838 BC, and listed as "medium grade". Isoflavones exist in a variety of plants and are recognized as an important class of substances in the field of herbal medicine extraction. Soybean is especially an important resource of isoflavones. At present, the research on isoflavones is mainly focused on the role of isoflavones as plant hormones, and its estrogen-like effects are believed to be due to their structur...
