    摘要： A novel crystalline form is defined by diffraction angle 2θ° of X-ray powder diffraction pattern and characteristic peak of differential scanning calorimetry (DSC). The novel crystalline form of Cefamandole Nafate is prepared as follows: adding Cefamandole Nafate in solid state to an organic solvent to form a suspension with a concentration of 0.04˜0.3 g/ml, stirring the suspension at 40˜50° C. for a period of time, and then cooling to 5˜15° C. at certain cooling rate, continuing to stir for a period of time, then suction filtrating the obtained suspension, the resulting filer cake is Cefamandole Nafate as wet product, which is dried to constant weight to provide the novel crystalline form of Cefamandole Nafate as final product.
