Complete 13 C and 1 H assignments for the oligosaccharide segment of a novel spirostanol glycoside were derived, and structural proof obtained, using a combination of DEPT, heteronuclear chemical shift correlation, homonuclear relayed coherence transfer, absolute value COSY, phase‐sensitive double quantum filtered COSY, NOESY, INEPT and proton‐detected long‐range heteronuclear shift correlation via multiple quantum coherence.
