Abstract: Degraded glucomannan was isolated from Abrus precatorius Linn. seed polysaccharide (Papilionaceae). Acid hydrolysis and methylation studies produced certain degraded methyl sugars as, 2, 3, 6-tri-O-methyl-D-glucose and 2, 3, 6-tri-O-methyl-D-mannose in 1:4 molar ratio. On the basis of hydrolysis and methylation experiments, a polysaccharide structure has been assigned to the degraded glucomannan and to the parent glucomannan of Abrus precatorius Linn. seed.
