, formally derived from anthraquinone by replacement of 8 hydrogen atoms by hydroxyl groups.

The compound was obtained in 1911 by Georg von Georgievics [1] [2] and can be obtained through oxidation of rufigallol (1,2,3,5,6,7-hexahydroxyanthraquinone) with boric acid and mercuric oxide in sulfuric acid at 250 °C (482 °F). [3]

Octahydroxyanthraquinone is active against the malaria parasite, but rufigallol (1,2,3,5,6,7-hexahydroxyanthraquinone) is 22 times more potent. [4]
