Conteúdo: |
In this study, we isolated and structurally characterized, for the first time, a galactoglucomannan (GGM) from the pulp of gabiroba, a Myrtaceae family species. The HPSEC-MALLS-RI analysis showed a homoge-neous polysaccharide with molar mass of 25,340 g mol−1. The monosaccharide composition showed thatthe GGM consisted of Man:Glc:Gal in a molar ratio of 1:1:0.6. Methylation and 1D and 2D NMR analysessuggested that the main chain of the GGM consisted of -d-Glcp and -d-Manp units (1 → 4)-linked. The-d-Galp substitutions occur mainly at O-6 position of -d-Manp units. The glycosidic linkages of theGGM were evident by the presence of the characteristic signals of 4-O-substituted residues at 78.6/3.69for both -d-Glcp and -d-Manp. Furthermore, the O-6 substitutions for both -d-Glcp and -d-Manpunits were confirmed by signals at 67.1/4.00 and 3.93. The interglycosidic correlations, obtained throughthe analysis of the HMBC spectrum, further confirm the structure. |
