ABSTRACT:
A process for the purification of riboflavine-5'-monophosphate comprising subjecting crude riboflavine-5'-monophosphate to chromatography using a column packed with a weakly basic anion-exchange resin having a skeleton of a crosslinked polyacrylic acid ester or polymethacrylic acid ester in which at least a part of the ester linkages thereof are converted into amide linkages represented by the following formula (1): ##STR1## to obtain a fraction of riboflavine-5'-monophosphate containing a reduced amount of impurities from an eluate of the column is disclosed.
