(±)-4,12,15,18,26-Penta-hydroxy-13,17-dioxahepta-cyclo-[14.10.0.0(3,14).0(4,12).0(6,11).0(18,26).0(19,24)]hexa-cosa-1,3(14),6(11),7,9,15,19,21,23-nona-ene-5,25-dione methanol disolvate.

The title compound, C24H14O9·2CH3OH, displays a chair-shaped form. The two di-hydro-indenone ring systems are located above and below the central fused-ring system, the dihedral angles between the mean planes of di-hydro-indenone ring systems and the mean plane of central fused-ring system are 67.91 (5) and 73.52 (4)°, respectively. In the crystal, extensive O-H⋯O hydrogen bonds, weak C-H⋯O hydrogen bonds and C-H⋯π inter-actions link the mol-ecules into a three-dimensional supra-molecular architecture.
