Results were treated by principal component analysis. Four chemotypes highlighted about leaves in an earlier work were confirmed: chemotype 1 (> 90% methyl chavicol), chemotype 2 (72–80% methyl eugenol), chemotype 3 (25–28% α-terpinene) and chemotype 4 (25–34% sabinene). The chemical composition of R. aromatica bark is in all cases characterized by a high amount of methyl chavicol (83–98%), whatever the chemotype. One can conclude that the bark oil of R. aromatica corresponds to the oil described previously under the name “oil of R. anisata.” DEWEY : 665 ISSN : 1041-2905 En ligne : http://www.jeoronline.com/archive/detail/47 [article] Chemical composition of essential oils from bark and leaves of individual trees of ravensara aromatica sonnerat [texte imprimé] / Hanitriniaina Sahondra Andrianoelisoa, Auteur ; Chantal Menut, Auteur ; Panja Ramanoelina, Auteur . - pp. 66-70.
