抄録

By allowing crystals or alcoholic solution of vitamin D2 to stand in air at a room temperature, 5% of it already undergoes decomposition in one week and the decomposition is accelerated thereafter, especially in crystals. This is assumed to be due mainly to air oxidation as well as by the action of light. It is suggested that the safest way is to store vitamin D2 in a brown bottle filled with inactive gas in an ice box. Several kinds of substances were separated by liquid chromatography as the decomposition product.
