For separation of riboflavin in paper ionophoresis, a 1% borax solution or a M/2O phosphate buffer of pH 5.6 was most satisfactory, but with an alkaline buffer there was decomposition of riboflavin. Alkaline decomposition products of riboflavin, lumichrome and lumiflavin were separated with difficulty by paper ionophoresis. The separation of riboflavin by ion exchange resin was prcduced fairly satisfactorily with Amberlite IRA-400,but with difficulty with other riboflavin related compounds.
