Abstract

The title compound (trivial name α-mangostin), C24H26O6, isolated from Cratoxylum glaucum, is characterized by a xanthone skeleton of three fused six-membered rings and two 3-methyl­but-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-methyl­but-2-enyl side chains are in (+)-synclinal and (-)-anti­clinal conformations. Intra­molecular O—H[cdots, three dots, centered]O and C—H[cdots, three dots, centered]O inter­actions occur. The crystal structure is stabilized by inter­molecular O—H[cdots, three dots, centered]O, C—H[cdots, three dots, centered]O and C—H[cdots, three dots, centered]π inter­actions.
