Objective: To establish a method for determining related substances of Ulipristal Acetate Tablets.Methods: HPLC was adopted and the separated was performed on a C18 column with a mixture of 0.01 mol·L-1 potassium dihydrogen phosphate and acetonitrile (35:65) as mobile phase.The flow rate was 1.0 mL·min-1 potassium dihydrogen phosphate and acetonitrile (35:65) as mobile phase.The flow rate was 1.0 mL·min-1 and the detection wavelength was set at 304 nm.Results: The main peak of Ulipristal Acetate Tablets was well separated from degradation impurities.The main degradation impurity N-demethyluipristal acetate was identified and assayed.Conclusion: The newly established method can be used for quality control of Ulipristal Acetate Tablets.
