The polyisoprenylated benzophenones machuone and clusiachromene A have been isolated from the fruits of Clusia columnaris. The hexane extract of the young branches with leaves afforded a new euphane derivative, whose structure was elucidated by spectroscopic methods. On the contrary, the most polar EtOAc and ButOH extracts were constituted of flavonoid C-glucosides (isovitexin, vitexin and vitexin-2"-xyloside) and seven biflavonoids of the so-called Garcinia group.
