 The essential oils isolated from twigs of Juniperus cedrus Webb & Berth. grown on Madeira consisted mainly of monoterpene hydrocarbons with α‐pinene (19-55%), limonene (17-32%) and Δ‐3‐carene (5-15%). Among other components were e.g. 1-octen‐3‐ol (1.0-2.2%), 1-octen‐3‐ol acetate (0-0.7%), bornyl acetate (0.2-0.9%), α‐terpinyl acetate (0.8-4.2%), carvacrol (0.2-2%), and caryophyllene (1.6-7.4%).  \\ The essential oils isolated from twigs of Juniperus cedrus Webb & Berth. grown on Madeira consisted mainly of monoterpene hydrocarbons with α‐pinene (19-55%), limonene (17-32%) and Δ‐3‐carene (5-15%).
