Co-Treatment with Phlorotannin and Extracellular Vesicles from Ecklonia cava Inhibits UV-Induced Melanogenesis

Antioxidants
Hyperpigmentation due to ultraviolet (UV)-induced melanogenesis causes various esthetic problems. Phlorotannin (PT) and extracellular vesicles (EVs) derived from various plants suppress melanogenesis pathways.

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

Marine 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

, 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.

Effects of Nutrient Enrichment on Growth and Phlorotannin Production in Fucus gardneri Embryos

, 2000
Resource-allocation models predict trade-offs between growth and chemical defense. The carbon/nutrient balance hypothesis (CNBH) predicts that plants will allocate carbon to growth when nutrients are abundant and allocate it to carbon-based antiherbivore

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

, 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 ...

Phlorotannin production and lipid oxidation as a potential protective function against high photosynthetically active and UV radiation in gametophytes of Alaria esculenta (Alariales, Phaeophyceae)

, 2011
Radiation damage can inter alia result in lipid peroxidation of macroalgal cell membranes. To prevent photo-oxidation within the cells, photoprotective substances such as phlorotannins are synthesized.

Free and bound phenolic profiles and antioxidant ability of eleven marine macroalgae from the South China Sea

Frontiers in Nutrition
Marine macroalgae are of broad interest because of their abundant bioactive phenolic compounds. However, only a few previous studies have focused on bound phenolic compounds.
