Abstract:
Provided are an inositol nicotinate crystalline form A and a preparation method therefor. The X-ray powder diffraction analysis, obtained by using Cu-Kα ray measurement, of the inositol nicotinate crystalline form A has obvious characteristic diffraction peaks at least at 2θ values, expressed in degrees, of 7.05, 7.41, 9.74, 17.80, 19.86, 23.57, 25.48 and 26.20 with an error range of +/−0.2°. The preparation method is one of or a mixed crystallization method of two or more of an evaporation crystallization method, a cooling crystallization method or an anti-solvent crystallization method. The process thereof is simple and easy to operate, and has more selectivity; the inositol nicotinate crystalline form A can be prepared by various methods, and the prepared product has a good crystallization degree and high chemical stability; and the inositol nicotinate crystalline form A prepared by the present method does not have the problem that a residual solvent is out-of-limit.

Claim (Index 2):
The crystal form A of inositol nicotinate of  claim 1 , wherein the X-ray powder diffraction of crystal form A expressed as 2\u03b8 value degrees has an obvious characteristic diffraction peak at diffraction angles of 7.05, 7.41, 9.74, 10.16, 11.26, 12.75, 17.80, 19.86, 20.97, 23.57, 25.48 and 26.20, 26.58, with an error range of \u00b10.2\u00b0.
