Phloroglucin

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


  • Phloroglucinol has been used to prevent hyperhydricity by promoting the lignification of shoots
  • It has also been used in PG (phloroglucinol)-sucrose treatments for the growth and development of in vitro derived shoot tips
  • Phloroglucinol has been used to stain root sections. It has also been used to stain plant sections to identify plant materials like lignin


Phloroglucinol displays antispasmodic activity. It is a trihydroxybenzene with antithrombotic, profibrinolytic, antimicrobial, antimalarial, cancer chemopreventive, anti-HIV, and anti-leishmanial activities. Phloroglucinol (PG) is a biosynthetic precursor of the 2,4-diacetylphloroglucinol (DAPG) an antibiotic against soil-borne diseases. Phloroglucinol is a useful intermediate because it is polyfunctional.
