چکیده انگلیسی
A water-soluble polysaccharide namely RCP-II from raspberry fruits was obtained by complex enzyme method followed by successive purification using macroporous resin D4020 and Sephadex G-100 columns. RCP-II was an acidic heteropolysaccharide and the characteristic structure of polysaccharide was determined. The carbohydrate of RCP-II was composed with galacturonic acid, rhamnose, arabinose, xylose, glucose and galactose in a molar ratio of 1.00:0.55:1.19:0.52:0.44:1.90 and the average molecular weight was estimated to be 4013Â Da, based on dextran standards. RCP-II presented high scavenging activity toward DPPH

The determination of the inhibitory activity on protein glycation showed that in 14 days of incubation the inhibitory ability of RCP-II was more effective on the development of non-enzymatic glycation reaction at early phase than that at the following two phases.
