Also present in Conium maculatum, this alkaloid may be obtained from the
residues remaining after removal of coniine as the hydrobromide or N-nitroso
derivative. It forms a colourless liquid, [α]20D - 81.92°. The hydrochloride is
crystalline, m.p. 19l-2°C; hydrobromide, m.p. 189-190°C; platinichloride,
orange crystals, m.p. 153-4°C and the aurichloride, m.p. 77-8°C. The picrate,
m.p. 121-2°C has also been prepared.
