Abstract:

The mollusk Cyclina sinensis has been widely used as a food and folk medicine in China, Korea and south eastern Asia. In this study, Total Water-soluble Extracts (TWE), Crude Polysaccharides (CPS), Total Crude Proteins (TCP) were isolated from C. sinensis and the Deproteinized Polysaccharides (DPS) was obtained after deproteination of CPS. Their contents, such as neutral carbohydrate, protein and uronic acid, were measured. Their antioxidative properties against 1, 1'-Diphenyl-2-Picrylhydrazyl (DPPH) free radical, hydroxyl free radical and superoxide anion free radical, as well as their reducing capacity were investigated. Results showed that various fractions of C. sinensis can scavenge all free radicals tested above and possessed the increasing reducing capacity in a dose-dependent mode. Compared with the other three fractions, TWE represents the comprehensively best antioxidative properties. The antioxidative activities of TWE from C. sinensis might contribute to antioxidant-related functional food and pharmaceutical industries.
