Abstract
The present invention is characterized in that racemic or optically active D- or L-α-glycerophosphoryl choline solids are prepared from liquid type racemic or optically active D- or L-α-glycerophosphoryl choline using an organic solvent. The present invention can produce solids at a high yield more easily through phase transformation rather than a method using a difference in solubility in a solvent, which is an existing method.
