The structure of the title natural product, 1′,5‐dihydroxy‐3′,7‐dimethyl‐2,2′‐binaphthalene‐1,4,5′,8′‐tetrone, C 22 H 14 O 6 , confirms the atomic connectivity postulated on the basis of spectroscopic data. The geometric parameters are normal and the angle between the planes of the two ring systems is 59.74 (2)°. The crystal packing is influenced by O—H⋯O hydrogen bonds, and possible short C—H⋯O and π–π stacking interactions.
