Abstract

The alkaloid picrasidine‐G was isolated from Picrasma quassioides. This alkaloid has previously been reported as a new natural product, but its ^13^C NMR signals still remain unassigned and some ambiguities remains in the proton assignments. Analysis of the ^1^H and ^13^C NMR spectra and 1 D NOE and 2D NMR spectra led to the unambiguous assignment of the ^1^H and ^13^C signals of picrasidine‐G.

Maltitol was assigned unequivocally without any need for reference to model compounds by a combination of 2D, SIMPLE (secondary isotope multiplets of partially labelled entities) and DIS (differential isotope shift) NMR techniques. The combination of these three techniques is very powerful for the a
