Reinvestigation of the phenolic constituents from a diethyl ether extract of gametophytes of Pellia epiphylla yielded pellepiphyllin, 7- hydroxypellepiphyllin, perrottetin E, perrottetin E-11-methyl ether, 14'- hydroxyperrottetin E, 10'-hydroxyperrottetin E, 10'-hydroxyperrottetin E-11- methyl ether, 10,10'-dihydroxyperrottetin E and 13',13'''-bis(10'- hydroxyperrottetin E). The structures of three bisbibenzyls published earlier are revised. The new structures have been elucidated by two-dimensional NMR- techniques and chemical synthesis. In contrast to previous publications, pellepiphyllin has been found as a constituent of P. epiphylla.

Two novel bis(bibenzyls) named paleatins A (1) and B (2) have been isolated from the liverwort, Marchantia paleacea var. diptera. Their structures have been established by a combination of high-resolution NMR spectra and chemical degradation. A total synt
