FUNDAMENTAL STUDIES ON RIBOFLAVIN SYNTHESIS (I) : ISOLATION OF ARABINOSE BY ION-EXCHANGE PROCEDURE

Abstract

The authors tried to purify arabinose solution by a system of Amberlite IRA-400 (-OH) and Amberlite IR-120 (-H), but it was undesirable as the sugar was partly decomposed by IRA-400 (-OH). However, the purification succeeded without decomposition when a system of Amberlite IR-120 (-H) and Amberlite IRA-400 (-CO_3) was used, and the yield of arabinose through the system was about 80 per cent.
