Three ent-eudesmenones from the liverwort Plagiochila bifaria.
The essential oil of the liverwort Plagiochila bifaria was analysed by GC and GC-MS. Three eudesmane type sesquiterpenes, ent-eudesm-4-en-6-one, ent-eudesm-4(15)-en-6-one, ent-7-hydroxyeudesm-4-en-6-one were isolated and identified as new natural products. Structure elucidation and the determination of absolute configurations are described.
