Abstract
The structures of some non-cellulosic S-Q-Glycans from three
plant sources have been investigated and each was found
to be characterised by
linked D-pyranosyl
a main chain consisting of S-(1-44)-
sugars. The polysaccharides were,
however, different in structural features in a manner
apparently related to their respective locations within the
organs of the plants concerned.
The polysaccharides were isolated and purified using
standard fractionation methods including chromatographic
techniques and selective precipitation methods. Structural
information was obtained by employing techniques such
as methylation analysis (involving use of gas liquid
chromatography mass spectrometry), optical rotation
measurements, mass spectrometry and n.m.r. spectroscopy on
the original polysaccharides and on degraded products
obtained by methods such as acid- or enzyme-catalysed
hydrolysis and Smith degradation.
The polysaccharide from a gum exudate found in Strelitzia
reginae flowers has been shown to be a highly substituted
S-(1~4)-Q-xylan, having . side-chains containing predominantly
terminal arabinofuranosyl, galactopyranosyl and
glucopyranuronosyl groups; in addition there are small
