Ixeris repens is a type of halophyte that grows in high salinity sands found in coastal sand dunes and sandy shores. This study was conducted to investigate the contents, antioxidant potency, and physiological activities of I. repens. In analyses of general composition, carbohydrate, protein, ash, and moisture content were 57.42%, 10.48%, 11.99% and 10.29%, respectively. Potassium, calcium, sodium, and magnesium were its most prevalent minerals. The solvents used to extract I. repens were 70% ethanol, 80% methanol, and distilled water. Among the resultant extracts, ethanol and methanol extracts displayed higher total polyphenol and flavonoid contents than the water extract. ABTS (IC50, 0.12 mg/mL) and FRAP (0.77 mM) radical scavenging activity were highest in the water extract, while methanol extract exhibited the strongest DPPH radical scavenging activity (IC50, 1.32 mg/mL), NO scavenging activity (IC50, 4.10 mg/mL), and reducing power (EC50, 0.14 mg/mL). Tyrosinase, elastase, and α-glucosidase inhibitory activities were highest in the ethanol extract. The ethanol extract also possessed the most potent acetylcholinesterase inhibitory activity. These results indicate that I. repens may be useful as an antioxidant, and a functional substance in food and pharmaceutical materials.
