Abstract
A new bis-norclerodane-type and two new clerodane-type diterpenoids we re isolated from the Japanese liverwort, Jungermannia infusca, togethe r with twelve known clerodane-, labdane- and ent-kaurane-type diterpen oids. These structures were determined by the use of NMR spectroscopic techniques, chemical degradation and X-ray crystallographic analyses. The presence of(+)- and (-)-isoabienol were confirmed by chiral HPLC analysis. (C) 1998 Elsevier Science Ltd. All rights reserved.
