Fig. 6: 1D and 2D NMR spectroscopy data of EpsA-O after solvolysis.

a 1D TOCSY spectra extracted from 2D spectra of sample SL1 obtained after solvolysis of EpsA-O recorded at 70 °C. b Ring region of the HSQC spectrum recorded at 70 °C of the sample SL1. Anomeric and methyl regions are reported in the insets. Peaks and cross peaks are labeled as in Table 3. Signals belonging to a glucose residue not part of the EpsA-O are labeled in grey.
