Abstract

A new clerodane- and two new ent-rosane-type diterpenoids have been isolated from the New Zealand liverworts Heteroscyphus billardierii and Plagiochila deltoidea, respectively. The known bisbibenzyl compounds and acetophenones have also been isolated from Schistochila glaucescens and Plagiochila fasciculata. Their structures were established by extensive NMR techniques. Chemosystematics of the Plagiochila species have been discussed.
