The complete assignments of 1 H and 13 C NMR data for a series of synthesized diosgenyl saponin analogs are described, viz. diosgenyl β‐ D ‐glucopyranoside ( 1 ), diosgenyl α‐ L ‐rhamnopyranosyl‐(1→2)‐β‐ D ‐glucopyranoside ( 2 ), diosgenyl α‐ L ‐rhamnopyranosyl‐(1→3)‐β‐ D ‐glucopyranoside ( 3 ), diosgenyl α‐ L ‐rhamnopyranosyl‐(1→2)‐α‐ L ‐rhamnopyranosyl‐(1→3)‐β‐ D ‐glucopyranoside ( 4 ), α‐ L ‐rhamnopyranosyl‐(1→2)‐β‐ D ‐xylopyranosyl‐(1→3)‐β‐ D ‐glucopyranoside ( 5 ), α‐ L ‐rhamnopyranosyl‐(1→2)‐β‐ L ‐arabinofuranosyl‐(1→3)‐β‐ D ‐glucopyranoside ( 6 ) and α‐ L ‐rhamnopyranosyl‐(1→2)‐β‐ D ‐glucopyranosyl‐(1→3)‐β‐ D ‐glucopyranoside ( 7 ). The assignments were achieved using homo‐ and heteronuclear two‐dimensional NMR techniques. Copyright © 1999 John Wiley & Sons, Ltd.
