Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A crystal of a calcium salt of pyrroloquinoline quinone, having peaks in 2θ at 7.7°, 10.6°, 19.1°, 26.4°, and 38.6° (each within ±0.4°) in powder X-ray diffraction using Cu Kα radiation, wherein the calcium salt of pyrroloquinoline quinone has a ratio of pyrroloquinoline quinone to calcium ions of about 1:1.5. 2. A crystal of a calcium salt of pyrroloquinoline quinone, having peaks in 20 at 9.8°, 15.3°, 17.1°, 19.7°, 26.3°, and 28.3°…
