- Vinblastine and vincristine occur in Catharanthus roseus (L). The plant contains only very small amounts of vinblastine and vincristine, and their isolation is correspondingly difficult. First the alkaloids present are separated by extraction into alkaloid tartrate soluble in benzene and alkaloid tartrates insoluble in benzene. Vinblastine and vincristine belong to the first group. They then are separated by chromatography on aluminum oxide deactivated with acetic acid.
- VINBLASTINE IS CLASS II IMMUNOSUPPRESSIVE DRUG, BUT IT HAS NOT BEEN EXPLOITED FOR THIS PURPOSE. /VINBLASTINE SULFATE/
