【Abstract】 Four polysaccharides precipitated by ethanol from the hull of water chestnut are reported. The monosaccharide compositions have been determined by their retention times and characteristic gas chromatography mass spectrometry fragmentation patterns. The polysaccharides are composed of arabinose, rhamnose, xylose , mannose, galactose, glucose, lactose and melibiose. The major monosaccharide components are determined as glucose, galactose, monose and xylose.更多还原
