摘要：

The title compound, C23H22O6.CH3OH, has an essentially planar xanthone nucleus fused to a chromene ring which adopts a sofa conformation. The 3-methylbut-2-enyl substituent is axially attached to the xanthone ring system, with a (+)-anticlinal conformation. The crystal structure is stabilized by O - H .......O and C - H..........O intramolecular and intermolecular interactions.
