Sulphated xylogalactans from Nothogenia fastigiata
Fractionation of the Cetrimide salt of the sulphated polysaccharides of Nothogenia fastigiata led to the isolation of a complex product constituted by a xylogalactan sulphate and a xylomannan sulphate. Its structural study by methylation and desulphation-methylation analyses and 13C NMR spectroscopy...
