The 1H and 13C NMR spectra of glucodigifucoside and glucogitoroside, cardenolides isolated from Digitalis lanata leaves, were completely assigned with the aid of 2D homonuclear (COSY) and heteronuclear (HETCOR and HMQC) correlation spectra. 1997

✦ Synopsis
Abstract
The ^1^H and ^13^C NMR resonances for ractopamine hydrochloride have been assigned. H,H‐COSY and H,C‐COSY were used to assign the aliphatic moiety of the molecule and to correlate protons and carbons on the same ring system. Long‐range selective proton decoupling (LSPD) experiments were used to assign quaternary carbons and to distinguish the two ring systems.

The complete assignments of 1H and 13C NMR data for a series of synthesized diosgenyl saponin analogs are described, viz. diosgenyl b-D-glucopyranoside (1), diosgenyl a-L-rhamnopyranosyl- 7). The assignments were achieved using homo-and heteronuclear two-dimensional NMR techniques.
In addition to 1D NMR methods and 2D shift-correlated NMR techniques (COSY and HETCOR), spin-spin simulation and MMX calculations, to obtain the minimum energy conformation structure, were used for the complete 1 H and 13 C NMR assignments of stephalic acid.
