From Brazilian Phoebe oil (essential oil of Phoebe porosa Mez. syn. Oreodaphne porosa Mez.) over 100 constituents could be identified by 'H-NMR spectra and GC-MS. The main constituents are carquejyl acetate (24,2.1 YO), the sesquiterpenes a-copaene (29,5.6%), y-(56,3.5%), and 6-cadinene (59,3.1 YO), cremoligenol(88, 8.4%), P-eudesmol (95, 8.4%), valerianol (97, -5%), a-bisabolol (102, 3.6%) and P-bisabolol (100, 2.9%). The structures of epi-sesquithujene (31) and of some trace constituents, oreodaphnenol (50, a 6,8-cycloguaian-4-ol) as well as the rare trans-a-bergamot-2-en-IO-one (69) and a new sesquiterpene ketone, porosadienone (99, an 6(7+8)-abeo-eudesmadienone), could be confirmed by spectral data.
