Most polyphenols contain repeating phenolic moieties of pyrocatechol, resorcinol, pyrogallol, and phloroglucinol connected by esters ( hydrolyzable tannins ) or more stable C-C bonds ( nonhydrolyzable condensed tannins ).
32.
Brown algae, such as " Ecklonia stolonifera ", " Eisenia bicyclis " or species in the genus " Zonaria ", produce phloroglucinol and phloroglucinol derivatives.

Phlobaphenes formation ( tannins condensation and precipitation ) can be minimized in using strong nucleophiles, such as phloroglucinol, " m "-phenylenediamine and urea, during pine tannins extraction.
35.
The compound was described in 1988 by G . Maier and others, who obtained it by pyrolysis of 1, 3, 5-cyclohexanetrione ( phloroglucin, the tautomeric form of phloroglucinol ).
36.
Catechol and resorcinol ( benzenediol ) types of polyphenols have two, and pyrogallol and phloroglucinol ( benzenetriol ) types have three phenolic hydroxyl groups, respectively, though mixing of these types within polyphenols is also possible.
37.
Phloroglucinol carboxylic acid is further decarboxylated to phloroglucinol, which is intradiol cleavage through protocatechuate 3, 4-dioxygenase and hydroxyquinol 1, 2-dioxygenase to form ?-carboxy cis, cis-muconic acid and maleyl acetate.

39.
The legume-root nodulating, microsymbiotic nitrogen-fixing bacterium species " Bradyrhizobium japonicum " is able to degrade catechin with formation of phloroglucinol carboxylic acid, further decarboxylated to phloroglucinol, which is dehydroxylated to resorcinol and hydroxyquinol.
