✦ Synopsis

H and I3 C NMR spectra of five marchantins isolated from Marchantia species (Liverwort) have been completely assigned using NOE difference, 13C-lH correlation, and long-range proton selective decoupling (LSPD) spectra. The structures of two macrocyclic bistbibenzyls) have been determined by use of this assignment. The marchantins are a new class of compound isolated from liverworts,') e.g. Marchantia polvmorpha, E. paleacea var. diptera, and &. tosana, and have
