Particulate organohalogens in edible brown seaweeds
Food Chemistry, 2019Brown algae, rich in antioxidants and other bioactive compounds, are important dietary seaweeds in many cultures. Like other marine macroalgae, brown seaweeds are known to accumulate the halogens iodine and bromine. Comparatively little is known about the chemistry of chlorine in seaweeds.

Antioxidant activities of enzymatic extracts from brown seaweeds
Bioresource Technology, 2005Potential antioxidative activities of enzymatic extracts from seven species of brown seaweeds were evaluated using four different reactive oxygen species (ROS) scavenging assays containing DPPH (1,1-diphenyl-2-pricrylhydrazyl) free radical, superoxide anion, hydroxyl radical and hydrogen peroxide scavenging assay.

Hemagglutinins in brown seaweeds
Journal of Experimental Marine Biology and Ecology, 1986Abstract Twenty-eight brown seaweeds contain agglutinins that show activity against animal and human erythrocytes. Three brown seaweeds are described whose hemagglutinic activity has not been previously reported: Ectocarpus confervoides, Giffordia granulosa and Cutleria multifida.

Carbohydrates of the brown seaweeds
Carbohydrate Research, 1974Abstract Mannitol, sucrose, and laminitol have been isolated from ethanolic extracts of the brown seaweed Desmarestia aculeata and characterised, and rhamnose, sedoheptulose, glucose, fructose, and 2- O -methyl- and 3- O -methyl-fucose have been identified by their chromatographic mobilities and g.l.c. retention times. Laminarin, alginic acid, and “

Brown Seaweed Extracts (Alginates)
2022Alginates, or algin, is a generic term for the salts and derivatives of alginic acid. This acidic polysaccharide or gum occurs as the insoluble mixed calcium, sodium, potassium, and magnesium salt in the Phaeophyceae, brown seaweeds. Brown seaweed has been used as a food for centuries but the discovery of algin did not occur until about 1880.

Conservation genomics of a critically endangered brown seaweed
Journal of Phycology, 2021Seaweeds provide valuable ecosystem services, but many are undergoing global decline due to climate and anthropogenic stressors. The brown macroalga, Nereia lophocladia (hereafter called Nereia), is among only a handful of seaweeds globally to be listed as critically endangered and is only described from two known locations, but there exists little ...

Antioxidant Activity of Brown Seaweeds
Journal of Aquatic Food Product Technology, 2016ABSTRACTAntioxidant potential of three brown seaweeds, Anthophycus longifolius, Sargassum plagiophyllum, and Sargassum myriocystum, obtained from the Gulf of Mannar region of India were evaluated utilizing different in vitro systems. Ethyl acetate (EtOAc) fraction of Anthophycus longifolius registered significantly greater hydroxyl radical scavenging ...

Nature Methods
Brown seaweeds are multicellular eukaryotes that have been evolving independently of animals and plants for more than a billion years. The filamentous brown alga Ectocarpus has been used as a model to understand the biology of these enigmatic organisms and to shed light on a range of major questions, from the molecular basis of complex developmental ...

Polysaccharides composition from tropical brown seaweeds
Phycological Research, 2012SummaryPolysaccharides composition of the tropical brown seaweeds Turbinaria turbinata, Sargassum filipendula, Dictyota caribaea and Padina perindusiata collected at Yucatan Peninsula (Mexico) was determined in this study. Crude fucoidan extracted with HCl and alginate extracted with a hot alkali solution were characterized in terms of their molecular ...
