/pəˈlɪpərɪk/

Origin: Formed within English, by derivation; modelled on a German lexical item. Etymons: Polyporus n., -ic suffix.

Etymology: < Polyporus n. + -ic suffix, after German Polyporsäure polyporic acid (C. Stahlschmidt 1877, in Ann. der Chem. u. Pharm. 187 180).

Biochemistry.

polyporic acid n. a bronze-coloured crystalline solid, C₁₈H₁₂O₄, which is a colouring matter found in certain fungi and lichens, and was first isolated from a fungus of the genus Polyporus; 3,6-dihydroxy-2,5-diphenyl-p-benzoquinone.

1877 Jrnl. Chem. Soc. 32 ii. 620 The fungus..seems to be closely allied to Polyporus purpurascens... When brought into contact with dilute ammonia, its colour changes to a fine deep violet, and it yields a solution from which hydrochloric acid throws down a yellow precipitate of the new acid—polyporic acid.

1931 Jrnl. Amer. Chem. Soc. 53 2373 Two of the important coloring matters found in fungi are polyporic acid..obtained from Polyporous [sic] nidulans and atromentin..from Paxillus atrotomentosus.

1957 R. H. Thomson Naturally occurring Quinones ii. 26 Polyporic acid also occurs in the fungus Peniophora filamentosa..and..has been found in two lichens.

2001 Jrnl. Nat. Products 64 1230 Suillusin is suggested to be biogenerated from polyporic acid.
