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.

✦ Synopsis
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.

1 H and 13 C NMR spectral data for phytochelatin, NH 3 C --Glu-Cys 2 -Gly-COO , were assigned by a combination of one-( 1 H, 13 C) and two-dimensional (DQF-COSY, CH-COSY, HMBC) NMR experiments.
The indole alkaloid strychnobrasiline was studied using one-and two-dimensional NMR techniques. The interpretation of these spectra led to the complete assignments of all carbon and proton chemical shifts.
