F.  aExtraction, purification and structural characterization of agalactoglucomannan from the gabiroba fruit (Campomanesia xanthocarpa Berg), Myrtaceae family.h[electronic resource]  c2017  aIn 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.  aCampomanesia xanthocarpa  aFruit pulp  aMannans  aEspécie nativa  aGuabiroba  aHemicelulose  aPolpa de fruta  aSacarídeo  aExtraction polysaccharide  aGabiroba  aGalactoglucomannan  aHemicelullose  aNMR analysis1 aRUTHES, A.
