The dihydroxy-9,10-anthraquinone functional group occurs widely in natural products, [3] [4] [5] and is an important feature of the anthracycline antitumour antibiotics. [ 6 ] [ 7 ] In particular, 1,8-Dihydroxy-9,10-anthraquinone is the precursor for the important topical antipsoriatic drug anthralin, 1,8-dihydroxy-9-anthrone, [ 8 ] [ 9 ]
1,5-Dihydroxyanthraquinone is an organic compound with the formula (C 6 H 3 OH) 2 (CO) 2. It is one of several isomers of dihydroxyanthraquinone. An orange solid, it is a component of traditional Chinese medications. [3] It serves as a chelating ligand for transition metals. [4]
1,4-Dihydroxyanthraquinone, commonly called quinizarin is a common hydroxyanthroquinone. [1] [2] In organic chemistry hydroxyanthraquinones refers to compounds with the formula C 12 H 8−n (OH) n (CO) 2 where n ≥ 1. Almost all hydroxyanthraquinones are derivative of 9,10-anthraquinone. [3] [4] [5]

Chorismate, formed by isochorismate synthase in the shikimate pathway, is a precursor of anthraquinones in Morinda citrifolia. [4] Tests for anthraquinones in natural extracts have been established. [5] Senna glycosides from the senna. Frangulin in Frangula alnus. Aloe-emodin in aloe resin. Carmine, a bright-red pigment derived from insects. [6]
1,4-Dihydroxyanthraquinone, also called quinizarin or Solvent Orange 86, is an organic compound derived from anthroquinone. Quinizarin is an orange or red-brown crystalline powder. It is formally derived from anthraquinone by replacement of two hydrogen atoms by hydroxyl (OH) groups.
