Seven new cadinane-type sesquiterpenoids (1–7) were isolated from the rhizomes ofStahlianthus involucratus. The planar structures of1–7were elucidated on the basis of extensive spectroscopic and HRMS data. The absolute configuration of1was determined by the single-crystal X-ray diffraction, ...
Three new cadinane-type sesquiterpenoids, (+)-4-muurolen-6α-ol, scapanol and ent-T-muurolol, were isolated from the liverwort Scapania undulata together with the previously known (+)-ent-epicubenol and phytol, and their structures determined by extensive NMR techniques.Access through your organ...
However, none of the diterpenoids were found to be active (ID(50)>50 microM).Two new bazzanane-type sesquiterpenoids have been isolated from the New Zealand liverwort Frullania falciloba. Their structures were confirmed by NMR and CD spectroscopy and chemical reactivity.Contact sensitivity to ...
