Abstract: 2D-NMR experiments of 1H-1H COSY,13C-1H COSY, JRES, RETIRES, RELAY and COLOC were applied to the studying of raffinose acetate (1), a model compound used in this research work. The results show that these techniques are useful for structure elucidation of natural glycosides. It is noted that COLOC is a powerful tool for the determination of sequence and interglycosidic linkages of sugar moieties.

Key words: 2D-NMR, Raffinose acetate
