 Commercial Douglas fir needle oils contained mainly monoterpenes like α-pinene (9.2-15%), β-pinene (17-31%), sabinene (7.2-20%), Δ3-carene (7-13%), and terpinolene (10-15%); monoterpene alcohols and esters like terpinen-4-ol (3.6-6.3%), citronellol (0.5-2.1%), citronellyl acetate (1.6-5.7%), and geranyl acetate (0.5-2.4%). Ester content reaches 3-8%. A prominent citric note is due to the presence of limonene, citronellol, and citronellyl acetate. \\ Commercial Douglas fir needle oils contained mainly monoterpenes like α-pinene (9.2-15%), β-pinene (17-31%), sabinene (7.2-20%), Δ3-carene (7-13%), and terpinolene (10-15%); monoterpene alcohols and esters like terpinen-4-ol (3.6-6.3%), citronellol (0.5-2.1%), citronellyl acetate (1.6-5.7%), and geranyl acetate (0.5-2.4%).
