• Beschreibung

  An aporphine alkaloid isolated from Michelia alba, M. champaca and M. compressa, this base forms colourless crystals from MeOH or EtOH. It is laevorotatory having [α]¹⁸_D - 117° (CHCI3 ). A methylenedioxy group, a non-phenolic hydroxyl group and a methylimino group are present.

• Occurrence

  Polyalthia oliveri yields this aporphine alkaloid. The base yields colourless needles when crystallized from MeOH and is laevorotatory with a specific rotation of [α]D -64° (c 0.5, CHCI3). It gives an ultraviolet spectrum in EtOH with absorption maxima at 236, 275 and 315 nm.
