1H-NMR spectra (D2O, 400 MHz) for oligosaccharide fractions of WBP (SNA-03, SNA-04) [27,28], CHEP (CJA1-02B, CJA2-03) [25,26,28], and CJS (CCA1-01, CCA1-02, CCA1-03, CCA2-01, CCA2-02) [25,29] with anomeric (4.3–5.2 ppm) and other characteristic proton resonances indicated on the spectrum of the GXGS heptasaccharide 2 at 600 MHz [28]. The cranberry GSGS octasaccharide 3 [28] is included to show the similarity of the 1H-NMR spectrum at 400 MHz for this purified material to those of complex mixtures containing structurally related compounds. Boxes indicate materials that are fractions from the same chromatographic separations.
