Cedrus libani A. Rich. - syn.Pinus cedrus L. - Pinaceae - Cedar of Lebanon, Libanon-Zeder

Evergreen tree, up to 50m tall, native to Western Asia (Cyprus, Lebanon, Syria, Turkey), widely planted as an ornamental tree in parks and gardens.

„Cedar wood is very prized for its fine grain, attractive yellow color and fragrance.“
https://en.wikipedia.org/wiki/Cedrus_libani

„As a result of centuries of over-exploitation, the tree now covers only 5% of its estimated ancient range in Lebanon (Davis et al. 1994). It is closely related to the other three Cedrus species: C.atlantica, from the Atlas Mountains of Morocco, C.deodara, endemic to the Western Himalayas and C.brevifolia, endemic to Cyprus.“

The scent of the slightly pressed needles can be described as piney, coniferous, slightly green and musky and is dominated by α-pinene, myrcene and caryophyllene. Green notes are added by (Z)-3-hexenal, (Z)-3-hexen-1-ol, and (Z)-3-hexen-1-yl acetate, and shades of a musky note is due to minor amounts of dodecano-12-lactone and tetradecano-14-lactone.

Cedrus libani wood essential oil hydrodistilled from fresh aerial parts showed 27 compounds by GC, accounting for 93.3 % of the total complex. Main components were α-himachalene (9.5%), β-himachalene (21.4%), and γ-himachalene (6.0%), together with α-(E)-atlantone (19.3%). Minor components were e.g. 4-acetyl-1-methylcyclohexene (0.1%), p-methylacetophenone (0.3%), and (E)-nerolidol (0.2%).
