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.

Phlorotannin Composition of Laminaria digitata

Phytochemical Analysis, 2017
AbstractIntroductionPhlorotannins are complex mixtures of phloroglucinol oligomers connected via C‐C (fucols) or C‐O‐C (phlorethols) linkages. Their uniformity in subunits and large molecular weight hamper their structural analysis. Despite its commercial relevance for alginate extraction, phlorotannins in Laminaria digitata have not been studied ...
