Abstract
A new acorane-and five new cuparane-type sesqui-and two new labdane-and two new seco- labdane-type diterpenoids have been isolated from the Japanese liverwort Jungermannia infusca (Mitt.) Steph., together with previously known sesqui-and diterpenoids. Their structures were determined by extensive NMR techniques, chemical degradation and X-ray crystallographic analysis.
