Strychnos henningsii is a South African species and the isolation of diaboline and its derivatives therefrom established a direct chemical link between American and African species (see also p. 194). Diaboline and a diacetyl Wieland-Gumlich aldehyde have also been isolated from the bark of the South American species S. chlorantha Prog. (12). The latter was identified by color reactions, chromatography, and mass spectrum (molecular formula C23H26N2O4), but insufficient material was available for further work.
