A steroidal alkaloid of Veratrum album, the base crystallizes as colourless prisms. It has [α]²⁰_D - 126° (c 0.65, pyridine) and - 76.6° (c 0.58, EtOH). The sulphate yields colourless crystals from aqueous EtOH, m.p. 250-3°C (dec.); [α]²⁰_D° - 175° (c 0.22, 75% EtOH) and the acetyl derivative forms prisms from Me2CO with one mole of solvent. The structure has been confirmed by the total synthesis of the alkaloid.
