Phlorotannins: A review on biosynthesis, chemistry and bioactivity
Food Bioscience, 2021 Abstract Phlorotannins are polyphenolic compounds mostly found in brown seaweed and are comprised of polymeric chains of phloroglucinol residues (1,3,5-trihydroxybenzene) connected via C–C and/or C–O–C couplings. Due to the presence of highly complex polymeric mixtures of structural and conformational isomers of phlorotannins and the absence of ...

Fucaceae: A Source of Bioactive Phlorotannins [PDF]
International Journal of Molecular Sciences, 2017 Fucaceae is the most dominant algae family along the intertidal areas of the Northern Hemisphere shorelines, being part of human customs for centuries with applications as a food source either for humans or animals, in agriculture and as remedies in folk medicine.

Pharmacological Applications of Phlorotannins: A Comprehensive Review
Current Drug Discovery Technologies, 2021Background: Seaweeds, including marine brown algae, are traditional food sources in Asia. Phlorotannins, as the product of the polyketide pathway, are mainly found in brown algae. Different properties have been attributed to this group of marine products ranging from antiallergic to anticancer activity. Mechanism of action is not obvious for all these

Food Research International, 2020 Phlorotannins are phenolic characteristic compounds of brown seaweeds that are only constituted by phloroglucinol (1,3,5-trihydroxybenzene). They are chain- and net-like structures of diverse molecular weights and have been widely identified in Ecklonia,

Phlorotannin-protein interactions
Journal of Chemical Ecology, 1996Tannins are one of the most broadly distributed types of plant secondary compounds, and have been the focal point for many studies of plant/herbivore interactions. Tannins interact strongly with proteins, so that the fate and effects of ingested tannins are in part dependent on the mode of interaction of the tannin with dietary and endogenous proteins ...

Phlorotannins are Polyphenolic Metabolites of Brown Algae
Russian Journal of Marine Biology, 2018This review is devoted to the analysis of publications on studies of phlorotannins, which are polyphenolic metabolites of brown algae. Their properties, the pathway of biosynthesis, and the structural diversity and classification of phlorotannins, as well as the methods for their isolation and determination of their metabolic profiles, are examined ...

Plasma-Polymerized Phlorotannins and Their Enhanced Biological Activities
Journal of Agricultural and Food Chemistry, 2020Here, we investigated the effect of cold plasma (CP) on the biological activities of phloroglucinol. Phloroglucinol (7.92 and 15.84 mM in methanol) was treated with air dielectric barrier discharge plasma at 250 W. In vitro, 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical-scavenging activity and ferrous-reducing antioxidant power (FRAP) values of ...

Phlorotannins of phaeophycea Laminaria ochroleuca
Phytochemistry, 1980Abstract From the mixture of acetylated phenols of Laminaria ochroleuca several fractions consisting of one or more components were isolated and analysed. Several substances, new or known from other seaweeds were identified: tetraphlorethol-A-nonacetate, fucophlorethol-B-octacetate, fucodiphlorethol-C-decacetate, pentafuhaloltridecacetate, and ...

Sustainable approach in phlorotannin recovery from macroalgae
Journal of Bioscience and Bioengineering, 2018In this present study, alcohol/salt liquid biphasic system was used to extract phlorotannin from brown macroalgae. Liquid biphasic system is a new green technology that integrated with various processes into one-step, by concentrating, separating and purifying the bioproduct in a unit operation.
