a water soluble polysaccharide, hb-1, with a molecular weight of 23,930, was isolated from radix ranunculi ternati. by hot water extraction, ethanol precipitation, deproteination，ultrafiltration and gel-filtration column chromatography. its sugar composition was determined by glc as glc, ara, and gal in a molar ration of 16.071: 2.722: 1. and the absolute configuration of glc was identified as ...

A capsular polysaccharide produced by Aerobacter aerogenes has been purified and shown to consist of galactose, mannose, and glucuronic acid in a molar ratio of 2: 1: 1, respectively. Partial acid hydrolysis liberated an aldobiouronic acid identified as 2-0-P-D-glucuronosyl-D-mannose. Analysis of capsular polysaccharide by Smith periodate degradation further indicated that all of the galactose ...

Pronase digestion of the lima bean lectin (Phaseolus lunatus (alpha-D-GalNAc greater than alpha-D-Gal)) afforded a glycopeptide of molecular weight 1380. Amino acid and carbohydrate analysis showed the glycopeptide to contain fucose, mannose, glucosamine, and aspartic acid in the molar ratios, 0.8:4.4:1.9:1.0. Methylation analysis, Smith degradation, and sequential degradation by specific glyco...
