The essential oils of the bark, fresh needles with twigs, air‐dried needles and twigs and fresh young needles of Douglas fir ( Pseudotsuga menziesii ) from Bulgaria were analysed by GC, GC – MS and olfactometry. More than 50 compounds could be identified by mass spectra and retention‐time correlations, as well as olfactory evaluations. As main compounds, the monoterpenes β‐pinene, sabinene, ( Z )‐β‐ocimene, ( E )‐β‐ocimene, α‐terpinolene, α‐terpineol, citronellyl acetate, α‐terpinene, limonene and γ‐terpinene were found. An odour description is given, as well as an assignment of the characterized odour to identified active oil constituents. Additionally, first data on biological tests of these natural products are discussed. Copyright © 2000 John Wiley & Sons, Ltd.
