Figure 2.

Structural analysis of the rhamnomannan present in the Sporothrix strains employing ¹³C-NMR and ¹H-NMR (A,B, respectively). On the image, the spectrum corresponding to the rhamnomannan fraction of S. schenckii strain MYA 4820 is presented as a representative spectrum of both, S. schenckii and S. brasiliensis strains under study. (A) The signals corresponding to the carbon atoms in the mannose and rhamnose residues are shown as arrows, red for mannose and black for rhamnose. The corresponding signals are shown in Table 1. (B) Show the presence of the methyl group belonging to rhamnose (1.18 and 1.17p.p.m.) and the signals correspond to the proton bound to carbon 5 next to the methylene group for carbon 6 in the mannose ring (3.32, 3.35, and 3.39p.p.m.).
