Extracellular Vesicles from Ecklonia cava and Phlorotannin Promote Rejuvenation in Aged Skin

open access: yesMarine Drugs
Plant-derived extracellular vesicles (EVs) elicit diverse biological effects, including promoting skin health. EVs isolated from Ecklonia cava (EV-EC) carry heat shock protein 70 (HSP70), which inhibits key regulators such as TNF-α, MAPKs, and NF-κB ...

Extrinsic factors influencing phlorotannin production in the brown alga Ascophyllum nodosum

open access: yes, 2000
: Many brown seaweeds contain high concentrations of phlorotannins (polyphenolics) that show extensive phenotypic variation, which can be generated by variation in a number of biotic and abiotic extrinsic factors.

Nutritional Significance of seaweed phlorotannins

open access: yes
Polyphenols, which are bioactive substances produced through acetate malonate pathway are present in significant amounts in brown algae. The phloroglucinol based polymers can be classified into different categories based on their bonding patterns and display a wide variety of structural complexities.

Correlation between the seasonal variations in phlorotannin content and the antiallergic effects of the brown alga Ecklonia cava subsp. stolonifera.

open access: yes
Here, we investigated the antiallergic effects of brown algae (Ecklonia cava subsp. stolonifera) harvested on the coast of Nishinoshima Town, Oki Islands, Shimane Prefecture, Japan. Specifically, we investigated whether the active components of E.

The Effects of Phlorotannin Concentrations of Brown Seaweeds (Phaeophyceae) On The Feeding Rates of The Black Sea Hare Aplysia Vaccaria

open access: yes, 2016
In marine ecosystems, herbivory plays a vital role in ecosystem functioning and structuring of seaweed communities. In response to herbivory, some seaweeds produce chemical defenses to deter consumption, including production of phlorotannins by brown ...
