To effectively remove salts from Suaeda japonica, extracts, an electrodialysis system was developed. The biological activities of non-desalted (NDS) and desalted S. japonica (DS) extracts were compared. The DS extract exhibited superior polyphenolic (6.26%) and carbohydrate (28.56%) contents. The IC50 values of the DS extract against DPPH radicals and hydrogen peroxide were 0.22 and 0.68 mg/mL, respectively, which was higher than that of the NDS extract. Neither the DS nor the NDS extract was cytotoxic in RAW 264.7 macrophages. Additionally, the DS extract had a higher NO inhibitory effect compared to the NDS extract in lipopolysaccharide (LPS)-activated RAW 264.7 macrophages. These data indicate that DS extracts have greater biological activity than do ND extracts, and application of the electrodialysis process may be useful in marine bioresource applications.
