Octahydroxyanthraquinone
Introduction '''Octahydroxyanthraquinone''' is an organic compound with formula , formally derived from anthraquinone by replacement of 8 hydrogen atoms by hydroxyl groups. The compound was obtained in 1911 by Georg von Georgievics 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 . Esters of octahydroxyanthraquinone, where all eight hydroxyls are replaced by straight-chain 1-alkanecarboxylate groups -()''n''-COO-, with ''n'' between 6 and 14, are liquid crystals and have been studied for possible LCD applications.Octahydroxyanthraquinone is active against the malaria parasite, but rufigallol (1,2,3,5,6,7-hexahydroxyanthraquinone) is 22 times more potent.
