Main industrial niaouli (Melaleuca quinquenervia) oil chemotype productions from Madagascar / Panja A. R. Ramanoelina in The journal of essential oil research, Vol. 20 n°3 (Mai/Juin 2008) 

Public ISBD [article]  in The journal of essential oil research > Vol. 20 n°3 (Mai/Juin 2008) . - pp. 261-266 Titre : Main industrial niaouli (Melaleuca quinquenervia) oil chemotype productions from Madagascar Type de document : texte imprimé Auteurs : Panja A. R. Ramanoelina, Auteur ; Jean Pierre Bianchini, Auteur ; Emile M. Gaydou, Auteur Année de publication : 2008 Article en page(s) : pp. 261-266 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Melaleuca  quinquenervia  Myrtaceae  Niaouli  Essential  oil  composition  1,8-cineole  Viridiflorol  (E)-nerolidol  Chemotypes  Principal  component  analysis  Olfactory  selection Résumé : The chemical composition of craft and industrial niaouli (Melaleuca quinquenervia) leaf essential oils from Madagascar has been investigated over ten years. Samples (159) which are representative of this country correspond each year to 1.5–2 tons essential oil production. Among the various components identified by GC/MS, twenty-one were used for statistical analyses, the major components were α- pinene (0.1–17%), limonene (0.0–12%), 1,8- cineole (0.0–71%), α- terpineol (0.0–12%), (E)-nerolidol (0.0–95%) and viridiflorol (0.1–36%). Niaouli essential oils from Madagascar were classified into three chemotypes using Principal Component Analysis (PCA): a cineole chemotype (49–62%), a viridiflorol chemotype (21–36%) and an (E)-nerolidol chemotype (56–95%). The 1,8-cineole chemotype is widespread, representing 92% of the samples investigated if the leaf collection is done at random. The chemotype choice for production is possible using tree selection by leaf olfactory selection before leaf harvesting for essential oil production.
