Abstract:
The present invention relates to the technical field of chemical drugs and crystal form processes, and to a pyrroloquinoline quinine B crystal form and a preparation method therefor. The present invention comprehensively characterizes the pyrroloquinoline quinine B crystal form by virtue of means such as X-ray powder diffraction analysis, thermo-gravimetric analysis, and differential scanning calorimetry analysis so as to find the fact that the pyrroloquinoline quinine B crystal form is high in crystallinity and low in hygroscopicity, and a regular crystal form can be formed, thereby facilitating process treatment and improvement of physical and chemical properties of a medicine, and improving the patent medicine performance. The preparation method for the pyrroloquinoline quinone B crystal form provided in the present invention is simple, easy to control, and high in reproducibility.

Claim (Index 1):
A crystal form B of pyrroloquinoline quinone, wherein the crystal form B of pyrroloquinoline quinone has 3 or more characteristic diffraction peaks selected from the following group consisting of: 11.10\u00b10.2\u00b0, 17.32\u00b10.2\u00b0, 19.40\u00b10.2\u00b0, 20.16\u00b10.2\u00b0, 20.53\u00b10.2\u00b0, 22.57\u00b10.2\u00b0, 26.14\u00b10.2\u00b0, 29.95\u00b10.2\u00b0, and 32.06\u00b10.2\u00b0.
