Abstract
The structures of some non-cellulosic β D-Glycans from three plant sources have been investigated and each was found to be characterised by linked D-pyranosyl a main chain consisting of β -(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.
