A boron-polysaccharide complex was purified from a Driselase digest of cell walls of radish roots. The complex had a molecular weight of 7.5 KDa and contained boron (0.232%, w/w), uronic acid (52.3%, w/w) and neutral sugars (32.4%). 11B-NMR spectroscopic analysis suggested that the boron was present as a tetravalent 1 : 2 borate-diol complex.
