Chemical properties


  • These belong to the same chemical family as similar chemicals found in foxgloves (Digitalis purpurea).
  • The milky sap contains a complex mix of chemicals, some of which are steroidal heart poisons known as “cardiac aglycones”.
  • The steroidal component includes an hydroxyl group in the C3β position, a second attached to the C14 carbon, a C/D-cis ring junction and an α,β-unsaturated-γ-lactone in the C17 position.
  • These can be a C19-aldehyde in place of the more usual methyl group in this position as well as additional hydroxyl functions and sometimes epoxide structures.
  • The features described are those required for toxicity but in addition there can be other substitutions into the steroid nucleus.
  • In the plants, the steroidal component is commonly attached via a glycosidic link to a 2-desoxy or a 2,6-didesoxy sugar molecule.
  • CONSTITUENTS  –  Glycoside (Calotropin)
