STUDIES ON THE INDUSTRIAL PRODUCTIN OF FLAVINADENINEDINUCLEOTIDE : (VII) PURIFICATION OF FLAVINADENINEDINUCLEOTIDE BY METALLIC SALT FORMATION, ESPECIALLY SILVER SALT

Abstract

Depositing conditions were observed with Ag, Hg, Cd, Ba, Ca, Zn and Pb-salts of FAD. FAD with nearly 90% purity was obtained from crude FAD through a process forming Ba- and Ag-salt and liberating the metal ions. It was concluded that purifying effect was principally due to the Ag-salt process, the yield of which was about 70% including the succeedng process.
