Method of extraction, fractionation and purification of compounds derived from the sorting polyphenolic rain-effect plants costs of using a resin has a high yield of adsorption and elution

摘要

This invention relates to a method for extracting, fractionating and purifying polyphenolic compounds originating from plants, wherein the purification is performed by adsorption on an adsorbing styrene-divinyl benzene resin, followed by the elution of the polyphenolic compounds.
