Sesquiterpene constituents of the liverwort Lophozia ventricosa
摘要:
The essential oil of Lophozia ventricosa was investigated and yielded the two new sesquiterpenoids ventricos-7(13)-ene and 6,7-epoxyeudesin-3-ene. The first has a new skeleton, which is named ventricosane and is numbered after the structurally closest known sesquiterpene skeleton pentalenane. The absolute configuration of the latter compound was established by conversion to known compounds. The isolated compounds and reaction products were investigated using enantioselective GC and extensive NMR measurements (H-1; H-1-H-1 COSY; HSQC; HMBC and NOE experiments). (C) 2005 Elsevier Ltd.
