Abstract :
The different fractions of ramie hemicellulose were sequentially extracted with alkali solution. The hemicellulose fraction, which is rich in d-glucose and d-mannose residues was extracted and fractionated by treatment with a solution of barium hydroxide. Four distinct polysaccharide fractions were obtained. Sugar analysis showed that two fraction were composed almost entirely (98 and 99%) of d-glucose and d-mannose residues. It was concluded that these polysaccharides could be regarded as glucomannans.
