Three alkaloids, viz. retrorsine, isatidine and a new alkaloid, paucicaline, have been isolated. 3. Paucicaline, probably C₁₈H₂₇O₈N, melts at 184°C. 4. The relative amounts of retrorsine and isatidine seem to vary with the age of the plant.en© 1949 ARC - Onderstepoort and Faculty of Veterinary Science, University of Pretoria (original). © 2017 University of Pretoria.
