摘要：
An object of the present invention is to provide an industrially useful method for producing a calcium salt of pyrroloquinoline quinone, without using large amounts of organic solvents, and highly pure crystals produced thereby. According to the present invention, a highly pure calcium salt of pyrroloquinoline quinone can be produced by reacting an alkali metal salt of pyrroloquinoline quinone with a source of calcium ions.
