Zusammenfassung:	PURPOSE:To provide a stabilization method almost free from change with the elapse of time in the 5,6,7,8-tetrahydrofolic acid and its derivative even when preserved for a long period, and having a high preservation effect. CONSTITUTION:The objective method comprises preserving the powder of the 5,6,7,8-tetrahydrofolic acid and its derivative at a low temperature in the coexistence of an inert gas and a deoxidizing agent, while isolating the outside air.
