The 2D NMR spectra of the CRP polysaccharides. A HSQC spectrum of CRP-WA (A1 the anomeric region). B HSQC spectrum of CRP-02A (B1 the anomeric region). C HMBC spectrum of CRP-WA and D CRP-02A. E NOESY spectrum of CRP-WA and F CRP-02A. G Putative structure of CRP-WA and H CRP-02A. Diagnostic NMR signals are labeled using the following notation: A_t/A_t’ = T-Araf, A_3,5 = (α1 → 3,5)-Araf, A₅ = (α1 → 5)-Araf, A₃ = (α1 → 3)-Araf, G_3,6 = (β1 → 3,6)-Galp, G_4,6 = (β1 → 4,6)-Galp, G₆ = (β1 → 6)-Galp; G₃ = (β1 → 3)-Galp; α/βG =  → 4)- α/β-D-Galp; GA₄ = 1,4- GalpA, eGA₄ = 1,4- GalpA(OMe), GA_3,4 = 1,3,4- GalpA, M₄ = 1,4-Manp; CRP = polysaccharides from C. reticulata Blanco peels
