Since 2016, the invasive halophyte has been colonizing mudflats along the western coast of South Korea. In order to minimize costs on expansion management and waste-treatment of collected biomass, the potential application of the collected biomass of was investigated. Ethanolic extracts and subfractions thereof (hexanes, methylene chloride, ethyl acetate, 1-butanol, and water-soluble) of the aerial and belowground parts of showed free radical-scavenging [2,2-diphenyl-1-picrylhydrazyl (DPPH), and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS)], tyrosinase inhibitory, and pancreatic lipase inhibitory activities. An ethyl acetate fraction derived from aerial parts (EA-a) showed the most potent radical-scavenging and pancreatic lipase inhibitory activities, whereas tyrosinase inhibition was mainly observed in the methylene chloride soluble fractions (MC-bg) and other lipophilic fractions (ethyl acetate and hexanes layers) obtained from belowground parts. The major EA-a compound isolated and identified was 1,3-di- - -feruloyl quinic acid ( ) based on spectroscopic analysis, whereas the two major MC-bg compounds were identified as -hydroxybenzaldehyde ( ) and - -feruloyltyramine ( ). Compounds and scavenged both DPPH and ABTS radicals, whereas and inhibited pancreatic lipase activity. These results indicate that extracts and fractions of have antioxidant, anti-obesity, and whitening properties with potential pharmaceutical, cosmeceutical, and functional food applications.
