Preparation and Chromatographic Analysis of Phlorotannins [PDF]

Journal of Chromatographic Science, 2013
In the 70s, reports began to appear of phenolic metabolites of brown algae with the characteristics of tannins; these compounds, initially termed phaeophyte tannins, marine algal polyphenols or polyphloroglucinols, are known as phlorotannins, the youngest group of plant polyphenolics.

Neuroprotective and antibacterial effects of phlorotannins isolated from the cell walls of brown algae Fucus vesiculosus and Pelvetia canaliculata [PDF]

, 2022
The Phaeophyceae (brown algae) essentially contribute to biotopes of cold and temperate seas. Their thalli are rich in biologically active natural products which are strongly and universally dominated with phlorotannins – polyphenols of complex and ...

Holdfast adhesion in the kelp Alaria marginata: Cell wall polysaccharides and phenolics. [PDF]

J Phycol
Abstract Adhesion is a critical process in the survival of seaweeds, especially in wave‐swept environments. Kelp (Laminariales) sporophytes secrete adhesives from specialized rhizoid cells to anchor themselves to the substrate and withstand immense forces applied by waves.

Fucophlorethol C, a phlorotannin as a lipoxygenase inhibitor [PDF]

Bioscience, Biotechnology, and Biochemistry, 2015
Abstract Fucophlorethol C, a phlorotannin, was isolated from the brown alga Colpomenia bullosa (Scyto-siphonaceae) as a novel lipoxygenase (LOX) inhibitor. It was obtained as a free form from natural origin for the first time. The compound inhibited a soybean LOX to the same extent as the known inhibitor nordihydroguaiaretic acid.
