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]
18D - 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.
