Description
Colchicum autumnale, Gloriosa virescens and Littoria modesta contain this alkaloid in the corms and seeds. It forms colourless needles from EtOH and is laevorotatory having a specific rotation of [α]D - 1190 (CHCI3). It has been separated from the associated bases in these plants by column chromatography and countercurrent distribution techniques.
