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 application of one-and two-dimensional nuclear magnetic resonance techniques to the structure elucidation of two saponins from Nothapodytes foetidu is reported. Detailed structural information about the sapogenin, protobassic acid, and the oligosaccharidic chains, including sugar sequence and position of glycosidation, is provided.
