Abstract:
The invention describes a polymorph of (R)-methyl-2-(3-aminopiperidin-1-yl)-3-(2-cyanobenzyl)-4-carbonyl-3,4-dihydrothiophene[3,2-d]pyrimidine-6-carboxylic acid maleate and a preparation method therefor. The polymorph is a crystal having high stability and low hygroscopicity, and the crystal form is selected from crystal form A, crystal form B and crystal form C. Furthermore, the crystal form has a strong in-vivo hypoglycemic activity and can be used for the preparation of a novel drug for the treatment or prevention of diabetes mellitus type H and/or complications of diabetes mellitus type H.

Claim (Index 2):
The crystal form of  claim 1 , wherein the \u201clow hygroscopicity\u201d means that the weight gain of crystal form A, crystal form B or crystal form C is calculated to be \u22641%, after being placed in a desiccator for 24 hours at a temperature of 80\u00b0 C. and a humidity of 80% and taken out.
