Abstract:
Fructo-oligosaccharides, extracted with hot water from wheat stems before flowering, were fractionated by gel-permeation chromatography on Biogel P2. The tri-/tetra- and penta-saccharide fractions were purified by HPLC and analysed by the reductive cleavage method. The trisaccharides 1-kestose and 6-kestose, the branched tetrasaccharide bifurcose, and the (2-->6)-linked pentasaccharide were identified. The fractions of higher molecular weight were also investigated and confirmed the branched-levan structure of this fructan.
