 "The yield and the chemical composition of Atlas cedarwood oil produced by two distillation modes and seven sample origins were determined. Steam distillation and hydrodistillation gave approximately the same yield (2.5-2.6 ml/100g). The samples from Adrej, Tounfite, Tamjilt and Ajdir gave the highest oil yields. The major constituents in the essential oil were α-himachalene (7.4-16.4%), γ-himachalene (5.1-8.6%), [[https://www.ebi.ac.uk/chebi/searchId.do;jsessionid=E4EB1055B5CC1AF70E06AF1420243A17?chebiId=CHEBI%3A49210|β-himachalene]] (23.4-40.4%) and [[http://webbook.nist.gov/cgi/cbook.cgi?ID=C108645541|(E)-α-atlantone]] (5.2-29.5%)." \\

+Major constituents of a commercial essential oil were β-himachalene (42.7%), α-himachalene (15.1%), γ-himachalene (9.5%), and (E)-α-atlantone (4.1%). Minor components were (Z)-α-atlantone (0.8%), (E)-γ-atlantone (1.0%), (4R,8R)-deodarone (1.1%), (4R,8S)-deodarone (1.0%), and 4-acetyl-1-methylcyclohexene (1.0%) e.g. \\

 In a GC-O investigation on Moroccan Atlas cedarwood essential oil following the AEDA methodology, (E)-α-atlantone was very weak or odorless for most evaluators. The most potent odorants were
 -acetyl-1-methylcyclohexene (Atlas cedarwood-like), vestitenone (citrus-lemon), p-cresol (phenolic, animal), 4-methylacetophenone (almond-like), undecan-2-one (aldehydic, coriander-like) and several nonidentified constituents. One of the strongest unknown components had a rather typical Atlas cedarwood note, but 4-acetyl-1-methylcyclohexene showed the highest FD factor and possessed a very characteristic cedarwood odor, thus may be considered as the principal key odorant of Atlas cedarwood oil. \\
