A definitive X-ray diffraction pattern suitable for the identification of vincristine sulfate crystals has not become available to the author. Vincristine may be readily isolated as the free base by making an aqueous solution of the sulfate alkaline with NH40H and extracting into an organic solvent such as ethylene dichloride, chloroform, or benzene. Therefore, the X-ray diffraction pattern of vincristine free base recrystallized from methanol is presented here13 31. The pattern was determined at a wavelength of 2.2896 if. using chromium radiation and a vanadium filter ...
