Isolation of a minor nitro-alkaloid from the aerial parts of Duguetia furfuracea--Annonaceae.
The refractionation of an alkaloidal extract of the leaves and twigs of Duguetia furfuracea has provided a minor aporphinoid alkaloid, named (+)-8-nitrous-isocorydine or (+)-1,2,3-trymethoxy-11-hydroxy-8-nitrous- aporphine. The structure of the new compound was elucidated by spectroscopic methods, notably 2D NMR and HRESIMS.
