Abstract

The invention comprises morpholine and ethanolamine salts of riboflavin-51-phosphate and their production from aqueous mixtures of isomeric riboflavin phosphates by reacting said mixtures with morpholine or diethanolamine and separating the resulting corresponding amine salt of riboflavin-51-phosphate from the corresponding amine-salts of its isomers by fractional crystallization. The pH of the mixture of amine salts obtained as a result of the reaction is adjusted between 4 and 10, and fractional crystallization effected by adding a water-miscible solvent, e.g. ethanol, acetone or isopropanol.
