Disclosed is a method for the enzymatic synthesis of flavonoid esters and flavonoid derivatives, according to which a) a reaction medium containing an organic solvent, a glycosylated flavonoid or aglycone flavonoid, an acyl group donor, and an enzymatic catalyst is produced, b) additional quantities of flavonoid and/or acyl donor are optionally added during the reaction, and c) the obtained esters are purified by eliminating enzymatic particles and the solvent. The inventive method is characterized by the fact that the concentration of water and/or alcohol which are formed during the reaction is controlled so as to be maintained below 150 mM. |
