Sustainable approach in phlorotannin recovery from macroalgae

Journal of Bioscience and Bioengineering, 2018
In 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.

Pharmacological Applications of Phlorotannins: A Comprehensive Review

Current Drug Discovery Technologies, 2021
Background: 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

Phlorotannin-protein interactions

Journal of Chemical Ecology, 1996
Tannins 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 ...

Multifunctional Gelatin/Chitosan Electrospun Wound Dressing Dopped with Undaria pinnatifida Phlorotannin-Enriched Extract for Skin Regeneration [PDF]

Pharmaceutics, 2021
The similarities of electrospun fibers with the skin extracellular matrix (ECM) make them promising structures for advanced wound dressings. Moreover, infection and resistance in wounds are a major health concern that may be reduced with antibacterial ...

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 ...

Plasma-Polymerized Phlorotannins and Their Enhanced Biological Activities

Journal of Agricultural and Food Chemistry, 2020
Here, 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, 1980
Abstract 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 ...

Quantitative determination of major phlorotannins in Ecklonia stolonifera

Archives of Pharmacal Research, 2010
Ecklonia stolonifera is a rich source of phlorotannins, which are responsible for the potent pharmacological effects associated with this seaweed. The purpose of this study was to develop a reversed-phase high-performance liquid chromatography method for the simultaneous determination of three major phlorotannins, eckol, dieckol, and ...

Phlorotannins are Polyphenolic Metabolites of Brown Algae

Russian Journal of Marine Biology, 2018
This 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 ...
