Beschreibung

First isolated from various species of Stemmadenia, this alkaloid has subsequently been found in DipZorrhynchus rondyZocarpon subsp. mossambiensis Benth. and MeZodinus australis. The following specific rotations have been reported; [α]19D + 310° (c 0.527, pyridine), [α]20D~O + 329° (pyridine) and [α]25D~S + 324° (pyridine). The alkaloid gives an ultraviolet spectrum exhibiting absorption maxima at 227, 284 and 292 m/J. with shoulders at 275 and 305 m/J.. One nitrogen atom is tertiary, the other being part of the indole ring. The solution in concentrated HN03 is a bright yellow.
