Abstract;A new compound phenanthrene type was isolated from the methanolic extract of the liverwort Marchantia tosana, together with the bibenzyl lunularin, p-hydroxybenzaldeyde and stigmasterol. The structure of the new compound was established as 2,7-dimethoxy-3-hydroxy-phenanthrene on the basis of its spectroscopic data. From the methanolic extract of the liverwort Plagiochasma japonica which has not been investigated before the diterpene 2-phyten-1-ol, the triterpene .ALPHA.-zeorin, the macrocyclic bis-bibenzyl riccardin D and stigmasterol have been isolated.
