Abstract:

The water-soluble matrix from abalone shell (WSMA) was purified by ion exchange chromatography (IEC) in DEAESephadex A-25 column. The antioxidant activity of WSMA was evaluated by scavenging capabilities of DPPH (1,1-diphenyl- 2-picrylhydrazy), hydroxyl (·OH) and superoxide anion (O2·) free radicals, and reducing powder of ferric ions. Compared with water-soluble matrix from pearl (WSMP) and vitamin C, WSMA revealed the similar reducing power and scavenging capability to O2· with WSMP, however, both WSMA and WSMP exhibited a weak inhibition effect on DPPH· and ·OH. The fraction from the second peak (AⅡ) separated by IEC was the major bioactive component. The scavenging capability of 1.0 mg/mL AⅡ to superoxide anion free radicals was 80%, which was equivalent to 0.1 mg/mL vitamin C.
