Method of enriching silybin with 2,3-dehydrosilybin and process for preparing 2,3-dehydrosilybin

摘要

method of enrichment silybinu 2,3 - dehydrosilybinem,where the solution silybinu in smesi water and proticku00fdch organic rozpouu0161tedel for basic catalyser at room temperature are the oxygen in the air according to the scheme 1.organic rozpouu0161tedlem is with advantage of ethanol, basis uhlicitan potassium catalyst.their preparation, tax-free 2,3 - dehydrosilybinu, where the solution silybinu in smesi water and proticku00fdch organic rozpouu0161tedel for basic catalyser at room temperature are the oxygen in the air,naceu017e dissolves in alcohol and clean 2,3 - dehydrosylibin vyprecipituje from aqueous solution of alkali metal hydrogenuhlicitanu, preferably hydrogenuhlicitanu sodium.organic rozpouu0161tedlem is with advantage of ethanol and basis uhlicitan potassium catalyst.in both cases, silybin used as part of the silymarinovu00e9ho complex where the silymarinovu00fdm complex is extracted from the seeds ostropestrce mariu00e1nsku00e9ho - silybum marianum, containing flavonoidu,in particular, silybinu, isosilybinu, silydianinu, silychristinu, 2,3 - dehydrosilybinu and other phenolic substances.
