Phlorotannins: A review on biosynthesis, chemistry and bioactivity

Food Bioscience, 2021
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.

Encapsulation of phlorotannins from edible brown seaweed in chitosan: Effect of fortification on bioactivity and stability in functional foods

Food Chemistry, 2022
Phlorotannins are a family of proven therapeutic agents. However, low stability disturbs their full bioactivity expression in the human body. Hence, this study focused on preserving their vitality through encapsulation.

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

Phlorotannins as bioactive agents from brown algae

Process Biochemistry, 2011
Abstract The importance of food bioactive compounds as functional ingredients has been well recognized due the effectiveness in promoting health and lead to the reduction of disease risk. Especially, nutraceuticals from seaweeds have been served as a rich source of health-promoting components.

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 ...
