The methyl-esterified rhamnogalacturonan cores of A-I and A-II were subjected to base-catalysed beta-elimination in the presence of sodium borodeuteride to give the neutral side-chains. Gel filtration showed that A-I contained a high-molecular-weight arabinogalactan and two oligosaccharides consisting of Ara and Gal or Ara as the side chains, and that A-II was composed of two high-molecular-weight arabinogalactans. Similar treatment of the acidic fraction, obtained by partial acid hydrolysis of A-I, gave mono- to tetra-galactosylgalactitol-1-d.
