Structural Characterisation of a Polysaccharide from Radix Ranunculus ternati
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 ...

متن کاملPolysaccharide labelling: impact on structural and biological properties
Three sulphated polysaccharides labelled at the reducing end with three different chemical treatments [2-aminopyridine (2-AP), 8-amino-1,3,6-trisulphonic acid (ANTS) and 6-(biotinyl)-aminocaproylhydrazide (BACH)] were compared. Molecular weight, chemical composition, nuclear magnetic resonance features and anticoagulant activity expressed as activated partial thromboplastin time were studied to...
متن کاملStructural and immunological studies on the pneumococcal C polysaccharide.
1. The C polysaccharide from pneumococci has been fractionated by gel filtration and by chromatography on diethylaminoethyl Sephadex. The results show that this material is composed of fractions ranging in molecular weight from 65,000 to over 200,000. Furthermore it was noted that all fractions contained the same hexosamine and amino acid components, but in markedly different proportions. 2. Wh...
