N2 - The water-soluble polysaccharide fraction, isolated from the bark of C. pentandra var. indica by delignification, contained l-rhamnose, d-xylose, l-arabinose, d-glucose, d-galactose, d-glucuronic acid, and d-galacturonic acid. Fractionation using Cetavlon and ethanol gave two acidic polysaccharides, each containing l-rhamnose, d-glucuronic acid, and d-galacturonic acid with mol. wts. of 1.318 × 106 and 1.445 × 105. On the basis of the results of methylation analysis of the native and carboxyl-reduced polysaccharides, partial hydrolysis, oxidation with periodate and chromium trioxide, and 1H-n.m.r. spectroscopy, the two acidic polysaccharides were concluded to have the following repeating unit. {A figure is presented}.
