초록

This study was designed to investigate the antioxidant effect of Suaeda japonica grown in Suncheon Bay. S. japonica was extracted using different solvents and the extracts were examined for their antioxidative activities with various methods. When the total phenolic contents were determined, the contents in the ethyl acetate, butanol and methanol extracts were 21.33, 17.31, and 2.33 mg/g, respectively. Fractions of butanol extract recorded the highest values of DPPH radical scavenging activity, β-carotene bleaching assay, and FRAP assay. The DPPH radical scavenging activities of butanol, ethyl acetate, methanol and water fractions were 77.46, 74.43, 47.99, and 27.70%, respectively. The FRAP value of butanol extract was 2.42 mM. But, the fraction of ethyl acetate extract was recorded the highest TBARS value. These results suggest that S. japonica, the specialty of Suncheon, could be a potential source of natural antioxidants.
