“…The major compounds 1-3 derived from bioactive fractions of S. anglica in this study are reported herein for the first time from this plant, although they have previously been reported from other plants as tyrosinase inhibitors with skin-whitening potential. The antioxidant activities of sulfur-containing organic acids; amino acids such as proline and glycine betaine, polysaccharides; and algicidal flavonols isolated from extracts of S. anglica have also been reported [17,18]. However, to the best of our knowledge, the present study is the first to investigate the radical scavenging, tyrosinase inhibitory, and pancreatic lipase inhibitory activities of sub-fractions of S. anglica extracts.…”

“…Previous chemical investigations of S. anglica have revealed the presence of dimethylsulfoniumpropanoic acid, proline, glycine betaine, and polysaccharides [13][14][15][16]. In addition, algicidal flavonols, such as isorhamnetin-3-O-sophoroside-7-O-rhamnoside and syringetin-3-O-galactoside, and antioxidant flavonols, such as 5,4 -dihydroxy-3 -methoxyflavonol-3-O-glucosyl-(1→6)-glucosyl-7-O-rhamnoside, 5-hydroxy-3 -methoxy-flavonol-3-O-glucosyl-(1→6)-glucosyl-7-O-rhamnoside, and 5-hydroxy-3 ,4 -dimethoxy-flavonol-3-O-glucosyl-(1→6)-glucosyl-7-O-rhamnoside, have been reported [17,18]. Apart from identifying these constituents, the biological activities of extracts of S. anglica, particularly the antioxidant activities of compounds derived from different plant parts, are yet to be investigated.…”

Since 2016, the invasive halophyte Spartina anglica has been colonizing mudflats along the western coast of South Korea. In order to minimize costs on S. anglica expansion management and waste-treatment of collected biomass, the potential application of the collected biomass of S. anglica was investigated. Ethanolic extracts and subfractions thereof (hexanes, methylene chloride, ethyl acetate, 1-butanol, and water-soluble) of the aerial and belowground parts of S. anglica 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-O-trans-feruloyl quinic acid (1) based on spectroscopic analysis, whereas the two major MC-bg compounds were identified as p-hydroxybenzaldehyde (2) and N-trans-feruloyltyramine (3). Compounds 1 and 3 scavenged both DPPH and ABTS radicals, whereas 1 and 2 inhibited pancreatic lipase activity. These results indicate that extracts and fractions of S. anglica have antioxidant, anti-obesity, and whitening properties with potential pharmaceutical, cosmeceutical, and functional food applications.

The phenolic content of Spartina maritima was investigated using chromatographic and spectroscopic techniques. Aqueous methanolic extracts were prepared from plant collected in different seasons in the Bay of Arcachon (French Atlantic coast). High performance liquid chromatography (HPLC) with diode array detection (DAD) coupled with mass spectrometry allowed identification of four major phenolics in the aerial tissue, all belonging to the C-glycosidic-flavonoid class. They were isolated from the crude extracts, and their structures were assigned to isovitexin, isoscoparin and their respective 2″-O-glucosides on the basis of NMR, mass and UV spectroscopies. The seasonal variation of the flavonoid content was quantified over the period January 2013 to May 2015. The total concentration found ranged from 1.73 to 4.60 mg g−1 dry wt for isovitexin derivatives, and 0.88–2.66 mg g−1 dry wt for isoscoparin derivatives. The phenolic content of the rhizomes was very low and mainly dominated by coumaric acid (0.03–0.08 mg g−1), along with ferulic acid (≤0.06 mg g−1). The lack of significant concentrations of flavonoids in the rhizome contrasts with the aerial tissue. This work constitutes the first phenolic profiling of S. maritima and should provide a foundation for further studies, considering the reported biological activities of C-glycosidic flavonoids, and the lack of knowledge of the phenolic chemistry of the genus Spartina.
