title: Dimeric phenylphenalenones from Musa acuminata and various Haemodoraceae species. Crystal structure of anigorootin.
abstract: Three fused octacyclic phenylphenalenone dimers were isolated from Musa acuminata: Anigorootin, which was first isolated from Anigozanthos flavidus and hitherto represented the only compound of that type, the new 4'-hydroxy-anigorootin, and 4',4"-di-hydroxy-anigorootin, which is a revised structure. The crystal structure of anigorootin was determined by X-ray crystallography. 3,3'-Bis-hydroxyanigorufone, a dimer of the conventional type known from Anigozanthos preissii, was also found in Musa acuminata. Phytochemical analysis of several Haemodoraceae species revealed the occurrence of anigorootin, 3,3'-bis-hydroxyanigorufone, and the novel metabolite 3,3'-bis-anigorufone. The occurrence of the same compounds in Musaceae and Haemodoraceae indicates the close chemotaxonomic relationship of both plant families.
