Description
The fruit of Alstonia venenata yield two closely related alkaloids which are
separated chromatographically. This base crystallizes as colourless rods from
MeOH and is strongly laevorotatory with a specific rotation of α] D - 427°
(CHC13). The ultraviolet spectrum in EtOH consists of absorption maxima at
220,295 and 326 nm.
