Physiological functions of phlorotannins
Biological Communications, 2018 Phlorotannins are the most abundant group of metabolites specific for brown algae. These substances contribute both to the primary and secondary metabolism of the algal cells and have practical relevance as biologically active compounds. The list of their presumable physiological functions is still not exhaustive and includes wound healing, chelation ...

Phlorotannin Composition of
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 ...
