| titleOfInvention | Steviol crystal in crystal form A, and preparation method and application thereof |
| abstract | The invention belongs to the technical field of medicinal chemistry, and particularly relates to a steviol crystal in a crystal form A, a preparation method and an application thereof, wherein the steviol crystal in the crystal form A has obvious characteristic diffraction peaks at least at positions of 7.76, 12.12, 14.18, 15.66, 16.04, 16.62, 19.2, 20.78, 24.00, 27.08, 31.72, 35.32 and 35.70 in degree of 2 theta angle by X-ray powder diffraction analysis measured by Cu-Ka rays. The crystal is characterized by using solid chemical analysis means such as XRD, DSC, TGA and the like, and the crystal has the advantages of high crystallinity, high stability and the like, and is suitable for wider application fields. The preparation method provided by the invention is simple, easy to operate, easy to control the crystallization process, high in selectivity and good in reproducibility, and can stably obtain the target crystal form. |
