Nutritional Significance of seaweed phlorotannins

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.

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

, 2017
In marine ecosystems, herbivory plays a vital role in ecosystem function and can drive seaweed community structure. In response to herbivory, some seaweeds produce chemical defenses to deter consumption, such as the production of phlorotannins by brown ...

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

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.

Effects of phlorotannin and nutrition concentration of brown seaweeds (Phaeophyceae) on feeding rates of the black sea hare Aplysia vaccaria.

, 2018
In marine ecosystems, herbivory plays a vital role in ecosystem function and can drive community structure. Feeding selectivity by herbivores may be influenced by numerous factors, including seaweed nutritional value and palatability.
