Watsonia pyramidata

A similar molecular structure is also proposed82 for the gummy polysaccharide from corm sacs of Watsonia pyramidata in which the (1— 4)-xylan backbone is highly substituted with 2- as well as 3-linked L-arabinofuranosyl side... [Pg.339]

The polysaccharides from the corm sacs of Watsonia pyramidata (andr.) Stapf.145 and from the seed boxes of Watsonia versveldii146... [Pg.371]

The presence of (1 —> 4)-linked chains of jS-D-xylopyranosyl residues in the Watsonia pyramidata polysaccharide was shown by the isolation, on partial hydrolysis with acid, of 4-0-/3-D-xylopyranosyl-D-xylopyranose (76), the corresponding xylotriose (84), higher oligo-... [Pg.372]

The influence of the arabinose substituent on hydration is illustrated by the unit-cell recorded for the gummy polysaccharide from corm sacs of Watsonia pyramidata where there seems to be two arabino-furanose units per backbone xylose unit. In this case, the hexagonal base plane expands to ( ) ... [Pg.257]
