Abstract

Fucoidan, a multifunctional marine polymer, is normally extracted from brown algae via extensive use of acid, solvent or high temperature water and a long reaction time. In present study, we developed a novel compressional-puffing-hydrothermal extraction (CPHE) process which primarily decomposes the cellular structure of algae and facilitates the release of fucoidan by hot water extraction. The CPHE process provides a number of advantages including simple procedure, reactant-saving, reduced pollution, and feasibility for continuous production. Sargassum glaucescens (SG) was utilized in this study, and the maximum extraction yield of polysaccharide was approximately 9.83 ± 0.11% (SG4). Thin layer chromatography (TLC), Fourier transform infrared (FTIR) analysis, and measurements of monosaccharide composition, fucose, sulfate, and uronic acid contents revealed that the extracted polysaccharide showed characteristics of fucoidan. All extracts exhibited antioxidant activities, and thus, further exploration of these extracts as potential natural and safe antioxidant agents is warranted.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • A compressional-puffing-hydrothermal process modifies macroalgal cellular structure before fucoidan extraction.

    “Other novel pre-treatments recently described in the literature include compressional-puffing-hydrothermal process consisting of heating at atmospheric pressure (140°C, 180°C and 220°C), followed by rapid reduction of pressure in a vessel containing superheated water, which allows the modification of the cellular structure of the macroalgae prior to extraction of fucoidan”
  • In vitro antioxidant activity of polysaccharides is mainly determined by DPPH, ABTS and FRAP assays.

    “The in vitro antioxidant activity of polysaccharides have been determined mainly by 1,1diphenyl-2-picryl hydrazil (DPPH) radical scavenging, ABTS radical scavenging and ferric reducing antioxidant power (FRAP) assays amongst others”
  • Macroalgal polysaccharides display antiinflammatory, immunostimulatory, antioxidant, anticoagulant, antimicrobial, antiviral, antipeptic, antiadhesive, antiproliferative, antiapoptosis and antitumour properties.

    “Macroalgal polysaccharides display a wide range of biological properties including antiinflammatory, immunostimulatory, antioxidant, anticoagulant, antimicrobial, antiviral, antipeptic, antiadhesive, antiproliferative, antiapoptosis and antitumour properties”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
