• Beschreibung

  This alkaloid has been obtained by Gadamer and Winterfeld during a systematic examination of the residues remaining after the isolation of chelidonine from Chelidonum majus L. The base forms colourless prisms on crystallization from EtOH and has [α]_D + 115.8°. It furnishes a crystalline hydrochloride and an aurichloride, m.p. 237-8°C. The O-acetate is amorphous, m.p. 147°C; [α]_D + 55.5°. One methoxyl group, two methylenedioxy groups, one hydroxyl group and a methylimino group are present in the molecule.
