Trisaccharides of Lolium and Festuca

The trisaccharide fraction of some monocotyledons

“…The use of paper chromatography has shown the presence of fructose-containing oligosaccharides in various monocotyledons: for example, in the leaves and stems of wheat (Bradfield & Flood, 1950;Lopatecki, Longair & Farstad, 1957), in onion bulbs (Egyptian 'Silvers'; Dr J. Edelman, personal communication, 1951), in leaves and stems of barley (Porter & Edelman, 1952) and in the seeds of cereals (MacLeod, 1951;White & Secor, 1953), but in very few cases have the substances been identified. Schlubach, Lubbers & Borowski (1955) have reported that 0-aX-D-glucopyranosyl-(1-->2)-0-fl-D-fructofuranosyl-(6--2) fl-D-fructofuranoside (6'-fl-fructosylsucrose; 'kestose') is the main trisaccharide of perennial ryegrass (Lolium perenne L.).…”

Isolation and Identification of Oligosaccharides Produced from Raffinose by Transgalactosylation Reaction of Thermostableα-Galactosidase fromPycnoporus cinnabarinus

“…25 ,26) Of these oligosaccharides containing an et( 1---+ 3)galactosidic linkage, oligosaccharide A has been isolated from the seeds of Lolium perenne and Festuca pratensis. 27 ) Within our knowledge, this is the first report about the isolation of oligosaccharides Band D.…”

Classification of Starch‐ and Fructosan‐accumulating Grasses as C‐3 or C‐4 Species by Carbon Isotope Analysis

“…Hirst (7) states that separate enzyme systems may be present in various plant parts. Thus, grass species that accumulate fructosans in their stem bases, store starch in their seeds (9,10), as do those that accumulate starch in their stem bases. * Likewise, fructosan-accumulators may synthesize fructosans of totally different molecular •Since submitting this manuscript, the starch-filled seeds of three Festucoideae species (Bromus inermis, Phleum pratense, and Dactytis gtomerata) that accumulate fructosans in their stem bases (Table I) were tested by carbon-isotope analysis.…”
