Abstract:
Three new clerodane-type diterpenoids have been isolated from the Japanese liverwort Jungermannia infusca (Mitt.) Steph., together with previously known compounds, nine clerodane- and four labdane-type diterpenoids, and 5-tocopherol. The structures of the new compounds were confirmed by 2D NMR experiments and X-ray crystallographic analysis.
