Bazzanines A-J, 10 cyclic bisbibenzyl derivatives with two biphenyl li
nkages and substituted with 1-6 chlorine atoms, as well as Bazzanin K,
a new dichlorinated macrocycle consisting of a phenanthrene and a bib
enzyl moiety also connected with two biphenyl linkages, have been isol
ated from the liverwort Bazzania trilobata. The structures have been e
