Parts Used

Chemical Composition
The milky sap contains a complex mix of chemicals, some of which are steroidal heart poisons known as "cardiac aglycones". These belong to the same chemical family as similar chemicals found in foxgloves (Digitalis purpurea). 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. In the plants, the steroidal component is commonly attached via a glycosidic link to a 2-desoxy or a 2,6-didesoxy sugar molecule
