Abstract

The title compound, C20H16O5, also known as 5,7-dihyr­oxy-3-(2′,2′-dimethyl-2H'-chromen-7′-yl)chroman-4-one, was isolated from the medicinal plant Ficus mucuso. The benzopyran­one (chromen-4-one) ring system is essentially planar and the dihedral angle between the benzopyranone ring system and the other benzene ring is 37.7 (10)°. In the crystal structure, one-dimensional chains are formed via inter­molecular O—H⋯O hydrogen bonds.
