The title compound, C38H50O6, also known as guttiferone A, was isolated from the medicinal plant Symphonia globulifera. It is a benzophenone derivative where one aryl group is derivatized to give a bicyclic system which has two prenyl groups attached to the bridgehead. One of the cyclo-hexane rings in the bicyclic system is in a chair form, while the other has a distorted half-chair conformation. In addition to an intra-molecular O - H⋯O hydrogen bond, inter-molecular O - H⋯O hydrogen bonds link mol-ecules into one-dimensional chains. © International Union of Crystallography 2007.
