TL;DR: The potential of one- and two-dimensional NMR techniques for the identification of individual sugar residues, their anomeric configuration, interglycosidic linkages, sequencing and the site of any appended group in establishing the structures of naturally occurring oligosaccharides and glycosides is presented.

TL;DR: The 13 C NMR chemical shifts of 130 naturally occurring steroidal sapogenins and saponin derivatives published up to 1983 are listed and a number of methods for signal assignment are explained as discussed by the authors.

TL;DR: These studies suggested the 25R‐orientation of the 27‐Me group for the furostanol glycosides isolated by Wu et al. from Tribulus terrestris.

TL;DR: In this article, the 13C NMR chemical shifts of 126 Steroidal sapogenins published between 1983 and 1993 are listed and critical spectral features and advances made in the NMR characterization of these compounds are discussed as a guide for the identification of the parent skeleton and the determination of substitution patterns.

TL;DR: In this article, 13C NMR shielding data for about 300 compounds are tabulated, and critical spectral features are discussed as a guide to the use of the technique in structure elucidation and stereochemical allocations of lignan, neolignan and their derivatives.
