ABSTRACT:
Salts of riboflavin 5'-phosphate which are obtained by phosphorylation of riboflavin and reaction of the resulting riboflavin 5'-phosphate (5'-FMN), contaminated with unconverted riboflavin and isomeric riboflavin monophosphates and diphosphates, with an alkali metal hydroxide or a nitrogen base are purified by a process in which
