Embodiment 1

[0070] Preparation method 1 of ulipristal acetate crystal type G substance sample:

[0071] Use acetone solvent to completely dissolve the ulipristal acetate sample at room temperature at 20°C, stir at 30°C for 24 hours to obtain the acetone solvate of ulipristal acetate, and place the solvate at 130°C Put it under 1 hour to remove solvent and prepare to obtain ulipristal acetate solid sample, carry out powder X-ray diffraction analysis to it, its diffraction picture Spectrum and figure 1 Consistent, indicating that the obtained sample is ulipristal acetate crystal G type solid matter.

[0072] Preparation method 2 of ulipristal acetate crystal type G substance sample:

[0073] Use ethanol solvent to completely dissolve the ulipristal acetate sample at room temperature at 20°C, stir at 30°C for 24 hours to obtain the ethanol solvate of ulipristal acetate, and place the solvate at 135°C Put it under 1 hour to remove solvent and prepare to obtain ulipristal acetate solid ...

[0079] Ulipristal acetate crystal G type solid substance stability characteristics:

[0080] High temperature test: put the crystal form sample in an open clean watch glass, place it at 60°C for 10 days, and take samples on the 0th day, the 5th day and the 10th day. The samples obtained from the above sampling points were subjected to powder X-ray diffraction analysis, and the diffraction picture spectrum mean figure 1 Consistent, showing that ulipristal acetate crystal G type solid matter is stable under the high temperature influence factor test.

[0081] High-humidity test: Put the crystal sample in an open clean watch glass, place it at 25°C for 10 days at a relative humidity of 90%±5%, and take samples on the 0th day, the 5th day and the 10th day. The samples obtained from the above sampling points were subjected to powder X-ray diffraction analysis, and the diffraction picture spectrum mean figure 1 Consistent, showing that ulipristal acetate crystal G type s...
