Abstract

The antioxidant activities of methanol and dichloromethane extracts of eighteen salt marsh plants were tested by using 1,1-Diphenyl-2-picryl-hydrazyl(DPPH) at a $100{\mu}g/ml$ concentrations. The methanol extracts of four salt marsh plants(Rosa rugosa Thunberg, Erigeron annuus, Ixeris tamagawaensis kitamura, Artemisia capillaris Thunberg) were found to be most effective in DPPH radical scavenging activity. The DPPH radical scavenging effect of these plants was Artemisia capillaris Thunberg(88.67%), Rosa rugosa Thunberg(87.51%), Erigeron annuus(78.49%), Ixeris tamagawaensis kitamura(69.99%) in order and was comparable with that of natural antioxidant, L-ascorbic acid(96.64%). The next effective ones were the methanol extracts of Teragonia tetragonoides(58.66%) and the dichloromethane extracts of Artemisia capillaris Thunberg(54.67%) and the others did not show a considerable activity. These salt marsh plants were evaluated using the pyrogallol UV-VIS spectrophotometeric method to generate superoxide anion. Among them, the dichloromethane extracts of four salt marsh plants and the methanol extracts of fifteen ones were weak superoxide dismutase-like activities.
