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
The diterpene ent-16a-hydroxykauran-18-oic acid was isolated from the leaves of Piliostigma thonningii. Structural elucidation and complete 1H and 13C NMR chemical shift assignments of this compound were achieved by 2D experiments.
