The Suppressive Activity of Fucofuroeckol-A Derived from Brown Algal Ecklonia stolonifera Okamura on UVB-Induced Mast Cell Degranulation

open access: yesMarine Drugs, 2018
UV light, especially UVB, is known as a trigger of allergic reaction, leading to mast cell degranulation and histamine release. In this study, phlorotannin Fucofuroeckol-A (F-A) derived from brown algal Ecklonia stolonifera Okamura was evaluated for its ...

Production and fate of macroalgal carbon in the ocean: How much do macroalgal organics matter?

open access: yesLimnology and Oceanography Letters, Volume 10, Issue 6, Page 799-814, December 2025.
Abstract Global carbon sequestration by macroalgae is hypothesized to rival rates in other blue carbon ecosystems. However, quantifying macroalgal carbon sequestration is challenging as it is hypothesized to occur outside macroalgal ecosystems, with 73% of sequestration occurring when dissolved organic carbon (DOC) is exported to deep ocean waters.

Slow-Binding Inhibition of Tyrosinase by Ecklonia cava Phlorotannins [PDF]

open access: yesMarine Drugs, 2019
Tyrosinase inhibitors improve skin whitening by inhibiting the formation of melanin precursors in the skin. The inhibitory activity of seven phlorotannins (1–7), triphlorethol A (1), eckol (2), 2-phloroeckol (3), phlorofucofuroeckol A (4), 2-O-(2,4,6-trihydroxyphenyl)-6,6′-bieckol (5), 6,8′-bieckol (6), and 8,8′-bieckol (7), from Ecklonia cava was ...

Latitudinal variation in the constitutive and inducible defences of a canopy‐forming rocky intertidal seaweed

open access: yesFunctional Ecology, Volume 39, Issue 12, Page 3718-3731, December 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract A long‐standing theory in biogeography is that stronger biotic interactions at lower latitudes select for better‐defended phenotypes. However, greater environmental variability at temperate latitudes may also shape defensive strategies by increasing temporal or local ...

Profiling of the Molecular Weight and Structural Isomer Abundance of Macroalgae-Derived Phlorotannins

open access: yesMarine Drugs, 2015
Phlorotannins are a group of complex polymers of phloroglucinol (1,3,5-trihydroxybenzene) unique to macroalgae. These phenolic compounds are integral structural components of the cell wall in brown algae, but also play many secondary ecological roles ...
