Application

  • Phloroglucinol (phlo) is a phenol derivative that shows cyctoprotective effect from oxidative damage by enhancing the activity of cellular catalase.
  • It can react with benzaldehyde derivatives to form phloroglucinol-based microporous polymeric organic frameworks (phlo-POF) with potential applications in ion-exchange and gas adsorption.
  • Phlo can also be used to prepare synthetic analogs of A-type proanthocyanidins (PACs) such as 2,8-dioxabicyclo[3.3.1]nonane derivatives by reacting with the corresponding flavylium salts.

Phlorotannins are complex mixtures of phloroglucinol oligomers connected via C-C (fucols) or C-O-C (phlorethols) linkages. Their uniformity in subunits and large molecular weight hamper their structural analysis. Despite its commercial relevance for alginate extraction, phlorotannins in Laminaria digitata have not
