“…An isolated doublet around 5.3 ppm is due to anomeric proton from glucose unit (1H-Clcp). The structure of 1′,2,3,3′,4,4′,6,6′-octa-O-acetylsucrose was additionally confirmed by the 13 C NMR spectrum (Fig. 3), where eight chemical shifts, characteristic for acetyl carbonyl, had clearly appeared at 170.72, 170.50, 170.13, 170.11, 170.05, 169.91, 169.68 and 169.53 ppm.…”
