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 ...

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

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.

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 ...

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 ...

Antioxidant activities of crude phlorotannins from Sargassum hemiphyllum

Journal of Huazhong University of Science and Technology [Medical Sciences], 2016
Brown algae are well known as a source of biologically active compounds, especially those having antioxidant activities, such as phlorotannins. In this study we examined the antioxidant activities of crude phlorotannins extracts (CPEs) obtained from Sargassum hemiphyllum (SH) and fractionated according to the molecular weights.

Antimicrobial effect of phlorotannins from marine brown algae

Food and Chemical Toxicology, 2012
Marine organisms exhibit a rich chemical content that possess unique structural features as compared to terrestrial metabolites. Among marine resources, marine algae are a rich source of chemically diverse compounds with the possibility of their potential use as a novel class of artificial food ingredients and antimicrobial agents.

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 ...

Extraction and Purification of Phlorotannins from Brown Algae

2015
The interest in the physiological roles and bioactivities of plant phenols has increased over the past decades. In seaweeds, many investigations have dealt with phenolic compounds of Phaeophyceae (phlorotannins), even though little is known so far about the ecophysiological variations of their pool or their biosynthetic pathways.

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 ...
