The title compound (trivial name α-mangostin), C(24)H(26)O(6), isolated from Cratoxylum glaucum, is characterized by a xanthone skeleton of three fused six-membered rings and two 3-methyl-but-2-enyl side chains. The three rings in the structure are nearly coplanar, with an r.m.s. deviation for the tricyclic ring system of 0.0014 Å. The two 3-methyl-but-2-enyl side chains are in (+)-synclinal and (-)-anti-clinal conformations. Intra-molecular O-H⋯O and C-H⋯O inter-actions occur. The crystal structure is stabilized by inter-molecular O-H⋯O, C-H⋯O and C-H⋯π inter-actions.
