HSCCC Separations of Rutin Esters Obtained by Enzymatic Reaction Catalyzed by Lipase
Journal of the Brazilian Chemical Society, 2021 The flavonoid rutin presents several pharmacological effects, despite this, its application in the pharmaceutical industry can be significantly limited by its low bioavailability. The development of lipophilic derivatives by esterification of hydroxyl groups with fatty acid chains may be an effective strategy to change their physicochemical properties.
