New Sesqui- and Diterpenoids from the Japanese Liverwort Jungermannia infusca (MITT.) STEPH.

Abstract

Two new peroxy cuparene-type sesquiterpenoids, a new 8, 9-seco-labdane-type diterpenoid and previously known compounds, have been isolated from the diethyl ether extract of Jungermannia infusca and their structures elucidated from 2D NMR and/or X-ray crystallographic analysis.
