Polysaccharides from the bark of the white willow ( Salix alba L.): Structure of an arabian

Abstract

A water-soluble arabinan [α] D — 141°, isolated from the bark of the white willow ( Salix alba L.), has a highly branched structure and consists of approximately 90 α- l-arabinofuranose residues variously linked ( 1→5), (1→ 3), and (1→2). Some of the l-arabinose residues are involved in branches through positions 2,3, and 5. The structure is essentially the same as that proposed for arabinans isolated from other plants.
