The significant features of the carbon-13 nuclear magnetic resonance spectra of viridopentaoses (1A, 1B and 1C), constituent pentasaccharides of N-acetylsporaviridin, and their degradation products (2-9) are discussed. The glycosidation shift was successfully applied to characterize the glycosidic linkages up to the tetrasaccharide level, whereas anomalous behavior was found in the pentasaccharides.
