(FR) EXTRACTION, PURIFICATION ET CONVERSION DE FLAVONOIDES PROVENANT DE PHYTOBIOMASSE
Abstract: front page image
(EN)A process for preparing a rutin-enriched composition from plant biomass comprises extraction with an aqueous solution, and precipitation. An enzyme preparation, such as naringinase, is used for the transformation of rutin to higher value compositions containing increased proportions of isoquercitrin and quercetin.
