Guiaflavine, a new bisindole quaternary alkaloid from the stem bark of Strychnos guianensis.
A reinvestigation of Strychnos guianensis resulted in the isolation of a colored quaternary bisindole alkaloid from the stem bark. The structure of this new substance, guiaflavine (1), was defined by detailed spectroscopic methods and comparison with model compounds.
