| titleOfInvention | Crystal form of sesquiterpene derivative, its preparation method and application |
| abstract | The present invention provides a crystal form of a sesquiterpene derivative, a method for preparing the same, and an application thereof. In the powder X-ray diffraction pattern of the crystal form A, the 2θ diffraction angles are 6.840 ± 0.2 and 9.390 ± 0. .2, 15.980 ± 0.2, 16.830 ± 0.2, 17.780 ± 0.2, 18.760 ± 0.2, 19.340 ± 0.2, 20.400 ± 0.2 , 21.910 ± 0.2, 23.280 ± 0.2, 25.520 ± 0.2, 26.680 ± 0.2, 27.490 ± 0.2, 32.110 ± 0.2, 32 It has characteristic diffraction peaks at positions corresponding to .300 ± 0.2, 37.980 ± 0.2 and 44.230 ± 0.2. The crystalline form A of the present invention has a high degree of crystallinity, almost no hygroscopicity, shows a more preferable elution kinetics, and has a bioavailability of 85.8%.
