Abstract:The polysaccharides from Hakka Rice Wine was separated by ion exchange chromatography, and a neutral component and an acid component were obtained. The neutral monosaccharide components G1 was purified by gel column, and the G1 was obtained. G1 was determined by GC-MS and HPLC-ELSD. The results showed that Hakka rice wine polysaccharide G1 mainly composed of glucose and also ribose, maltotriose, arabinose, mannose, isomaltotriose xylose, galactose and isomaltose.The infrared spectrum result showed that the characteristic absorption peak of mannose was obtained by infrared spectroscopy. The Hakka rice wine polysaccharide G1 was a heteropolysaccharide that composed of 17 monosaccharides and contained α-type,β-type glycoside, pyrone-based, and no glucuronic acid.
