摘要： The present invention relates to I- and II-type crystals of L-α-glyceryl phosphoryl choline, and to a method for preparing same. More particularly, the present invention relates to noble I- and II-type anhydride crystals of L-α-glyceryl phosphoryl choline, which have a higher purity than conventional liquid L-α-glyceryl phosphoryl choline, and one advantage of which is that formulations and dosages of pharmaceuticals are easily modified, and another advantage of which is that the hygroscopicity of the crystals are much lower than that of conventional polymorphic crystals, providing excellent stability during storage. The present invention also relates to a method for preparing the I- and II-type crystals of L-α-glyceryl phosphoryl choline.
