Strychnochrysine, a New Bisindole Alkaloid from the Roots of Strychnos nux-vomica1
The reinvestigation of Strychnos nux-vomica resulted in the isolation of a colored monoquaternary bisindole alkaloid from the roots. The structure of this new orange substance, strychnochrysine (1), was defined by detailed spectroscopic methods.
