From the root bark of Sorocea bonplandii Baillon (Moraceae), collected in Paraguay, four new isoprenylated phenols, sorocenols C (1), D (2), E (3), and E (4) were isolated along with four known isoprenylated phenols, mulberrofuran K (5), kuwanon J (6), chalcomoracin (7), and kuwanol E (8). The structures of sorocenols C -F were shown to be 1 - 4, respectively. These compounds are regarded as variations of Diels-Alder type adducts between chalcone derivatives and dehydroisoprenylated phenols.
