Abstract Heteronuclear correlation techniques and homonuclear E.COSY spectra were used to obtain a complete assignment of the 13 C and 1 H NMR spectra of the aglycone tomatidine. In addition, 1D/2D TOCSY, NOESY and ROESY spectra allowed the assignment of the sugar moiety in tomatine. The procedure used is of general applicability for the structural elucidation of sugars and glycosidic biomolecules.
