Abstract
A heteropolysaccharide isolated from the gum (Katira) of Cochlospermum religiosum was found to consist of d-galactose, d-galacturonic acid and l-rhamnose in a molar ratio 2:1:3. Structural assignment of the polysaccharide was carried out using total acid hydrolysis, methylation analysis, periodate oxidation, Smith degradation and NMR studies (1H, 13C, DQF-COSY, TOCSY, NOESY, HMBC and HSQC) and the repeating unit of the polysaccharide was established asFigure optionsDownload full-size imageDownload as PowerPoint slide
