    摘要: There is disclosed a new crystalline form of 7-(dimethylaminomethylene)amino-9a-methoxymitosane having an infra-red spectrogram as disclosed in the drawing. This new crystalline form is characterized by substantially greater storage stability than amorphous 7-(dimethylaminomethylene)amino-9a-methoxymitosane.
