Abstract: In this paper, the chemical structure of Nebmycin T was investigated by NMR. This method based on various kinds of NMR spectra, which included 1H、13C、DEPT、COSY、R-COSY、LR-COSY、NOESY and 2D-J, is successful in determination of structure of Nebmycin T. The results showed that Nebmycin T is an aminoglucoside compound. Their configurations were assigned based on the 2D-J spectrum. We determined the positions of amino-groups in Nebmycin T with the solvent effect.
