Antifungal activity of phlorotannins against dermatophytes and yeasts: approaches to the mechanism of action and influence on Candida albicans virulence factor. [PDF]

PLoS ONE, 2013
In the last few decades, fungal infections, particularly nosocomial, increased all around the world. This increment stimulated the search for new antifungal agents, especially those derived from nature.

A Key Step in Phlorotannin Biosynthesis Revealed [PDF]

The Plant Cell, 2013
Phlorotannins are a diverse set of polymers synthesized by brown algae, but their physiological functions are not well understood. They are structurally analogous to terrestrial plant tannins and are proposed to be important in cell wall structure, UV protection, and defense against herbivores ([

Latitudinal variation in phlorotannin contents from Southwestern Atlantic brown seaweeds [PDF]

PeerJ, 2019
Phlorotannins are primary and/or secondary metabolites found exclusively in brown seaweeds, but their geographic distribution and abundance dynamic are not very well understood.

Structure dependent antioxidant capacity of phlorotannins from Icelandic Fucus vesiculosus by UHPLC-DAD-ECD-QTOFMS [PDF]

, 2018
Brown algae are rich in polyphenolic compounds, phlorotannins, which have been found to possess high in vitro antioxidant capacity, especially DPPH radical scavenging activity, due to the high number of hydroxyl groups.

Constitutive or Inducible Protective Mechanisms against UV-B Radiation in the Brown Alga Fucus vesiculosus? A Study of Gene Expression and Phlorotannin Content Responses.

PLoS ONE, 2015
A role as UV sunscreens has been suggested for phlorotannins, the phenolic compounds that accumulate in brown algae in response to a number of external stimuli and take part in cell wall structure.

Decoupling Amplitude, Energy Input and Contact Time in the Ultrasound‐Assisted Extraction of Ascophyllum nodosum Bioactives

Advanced Chemical Engineering, Volume 1, Issue 2, December 2026.
This study showed that ultrasound amplitude had little influence on seaweed solubilization when energy input and contact time were controlled. Increasing energy improved solubilization and protein recovery but reduced antioxidant responses, while biomass loading affected extract composition.
