전기투석시스템을 활용한 염생식물 칠면초(Suaeda japonica) 추출물의 염분 표준화에 따른 주요 성분 및 생리활성 비교 연구
2016
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 applica-tion of the electrodialysis process may be useful in marine bioresource applications.
