A prenylated biphenyl was isolated in a re-examination of the roots of Clusia paralycola and attributed the structure (5a) and the name clusiaparalycoline D for the similarity with other biphenyls isolated from the same source. A second product, isomeric with the previously isolated paralycolin A, was assigned a 9,10-dihydrophenanthrene structure (6a) and named paralycolin B.
