TABLE 3.

NMR ¹H chemical shift assignments

The chemical shifts, given in ppm, were assigned from analysis of two-dimensional COSY and two-dimensional TOCSY spectra. The values in italics were assigned from the TOCSY spectrum alone. The axial and equatorial assignments of the Xyl H5 protons are indicated by a and e, respectively. Me denotes the methyl protons of Fuc and Rha, Ac denotes the methyl protons of GlcNac.
