✦ Synopsis

Complete ''C and '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 protondetected long-range heteronuclear shift correlation via multiple quantum coherence.

## Abstract The chemical structure of a plant growth substance, calonyctin A, was determined by NMR spectroscopy. The ^13^C and ^1^H spectral assignments were obtained using a combination of DEPT, heteronuclear chemical shift correlation, ^1^H–^1^H COSY, ^1^H–^1^H NOESY and inverse long‐range ^1^H–
