Impact of a (poly)phenol-rich extract from the brown algae Ascophyllum nodosum on DNA damage and antioxidant activity in an overweight or obese population: a randomized controlled trial [PDF]
, 2018 Background Epidemiologic evidence suggests that a diet rich in (poly)phenols has beneficial effects on many chronic diseases. Brown seaweed is a rich source of (poly)phenols. Objective The aim of this study was to investigate the bioavailability and

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 ...

Gastrointestinal modifications and bioavailability of brown seaweed phlorotannins and effects on inflammatory markers [PDF]
, 2016 Brown seaweeds such as Ascophyllum nodosum are a rich source of phlorotannins (oligomers and polymers of phloroglucinol units), a class of polyphenols that are unique to Phaeophyceae.

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 ...

Asymmetric synthesis of gonytolide A: strategic use of an aryl halide blocking group for oxidative coupling [PDF]
, 2018 The first synthesis of the chromanone lactone dimer gonytolide A has been achieved employing vanadium(V)-mediated oxidative coupling of the monomer gonytolide C. An o-bromine blocking group strategy was employed to favor para- para coupling and to enable

Antifungal and Larvicidal Activities of Phlorotannins from Brown Seaweeds [PDF]
Marine Drugs, 2021 Phlorotannins are secondary metabolites produced by brown seaweeds with antiviral, antibacterial, antifungal, and larvicidal activities. Phlorotannins’ structures are formed by dibenzodioxin, ether and phenyl, ether, or phenyl linkages. The polymerization of phlorotannins is used to classify and characterize.

Induction of defences and within-plant variation on palatability in two brown algae from the northern-central coast of Chile: effects of mesograzers and UV radiation [PDF]
, 2005 Macroalgae possess different defense mechanisms in response to herbivory. Some species produce anti-herbivore secondary metabolites, but production of these substances can be costly.
