[Purification and properties of polysaccharide PPIII from Sterculia lychnophora Hance].
Polysaccharide PP III was isolated and purified from aqueous extract of the seeds of Sterculia lychnophora. It is composed of galactose, arabinose and rhamnose, the molar ratio being 1 : 1.67 : 1.01 and molecular weight 162200. Rhamnoses in the main chain are linked by alpha-(1-->3) glycoside linkage. PP III C is its major fragment, and is composed of galactose and rhamnose with a molar ratio of 1 : 2. 78 and MW 62500.
