Characterization of the portuguese-grown cistus ladanifer essential oil / Paula B. Gomes in The journal of essential oil research, Vol. 17 N° 2 (Mars-Avril 2005) 

Public ISBD [article]  in The journal of essential oil research > Vol. 17 N° 2 (Mars-Avril 2005) . - pp. 160-165 Titre : Characterization of the portuguese-grown cistus ladanifer essential oil Type de document : texte imprimé Auteurs : Paula B. Gomes, Auteur ; Vera G. Mata, Auteur ; A. E. Rodrigues, Auteur Année de publication : 2006 Article en page(s) : pp. 160-165 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Cistus  ladanifer  Cistaceae  Rockrose  Essential  oil  composition  Viridiflorol Résumé : The chemical composition of the cistus oil from Portuguese-grown rockrose (Cistus ladanifer) was determined using GC and GC/MS. A comparison was also made in terms of the geographical source and use of either dry or fresh plant material. The cistus oil herein obtained was richer in amber-like compounds and had a low content of monoterpenes when compared to the usual values found in the literature. Moreover, it presented a relatively high content of ambrox (amber odor), which usually is only reported in labdanum oil. The major constituents were three sesquiterpene alcohols: viridiflorol (13.6–17.4%), globulol (3.1–5.0%) and an unknown sesquiterpene alcohol (2.7–6.0%), as well as the diterpene alcohol 15-nor-labdan-8-ol (1.7–5.2%). Three samples of commercially available cistus oil were also analyzed and compared.
