Abstract:
A 2,3-seco-cuparane-type sesquiterpenoid and the previously known barbatane-type sesqui- and ent-kaurane-type diterpenoids were isolated from the Japanese liverwort Jungermannia infusca (Mitt.) Steph. The structure of the 2,3-seco-cuparane-type sesquiterpenoid was determined by NMR spectroscopic analyses.
