Rufigallol or 1,2,3,5,6,7-hexahydroxy-9,10-anthraquinone is an organic compound with formula C
₁₄O
₈H
₈. It one of several hydroxyanthraquinones. It occurs naturally being derived from gallic acid.

The compound is soluble in dioxane, from which it crystallizes as red needles that sublime without melting at 365 °C.^[1] It can be obtained by treating gallic acid with concentrated sulfuric acid and then with sodium hydroxide.^[1] It is prepared by acid-catalyzed condensation of a pair of gallic acid molecules.^[2]

Rufigallol is particularly toxic to the malarial parasite Plasmodium falciparum and has a synergistic effect in combination with the antimalarial drug exifone, which has structural similarities to rufigallol.^[3]

Rufigallol forms a crimson-colored complex with beryllium, aluminium, thorium, zirconium and hafnium, and this reaction has been used for the spot and spectrophotometric determination of beryllium in low concentrations.^[1]
