Mohd., Auteur Année de publication : 2006 Article en page(s) : pp. 613-617 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Plumeria  obtusa  Plumeria  acuminate  Plumeria  rubra  Apocynaceae  Essential  oil  composition  Benzyl  salicylate  Benzyl  benzoate  Hexadecanoic  acid  Tetradecanoic  acid  Dodecanoic  acid  Linoleic  acid  (E)-nerolidol Résumé : The fower oils of four Plumeria L. species; P. obtusa L., P. acuminata Ait. (yellow fower), P. rubra L. (pink fower) and P. rubra (orange fower) hydrodistilled from samples grown on peninsular Malaysia, were analyzed by gas chromatography on two columns of different polarity and GC/MS. The oil of P. obtusa was found to be rich in benzyl salicylate (45.4%) and benzyl benzoate (17.2%), but also minute concentrations of alkanoic acids. Oil obtained from P. acuminata was rich in palmitic acid (36.2%), linoleic acid (16.8%), lauric acid (10.4%) and myristic acid (10.3%). The pink fowered P. rubra oil was similar to P. acuminata oil in that it was also devoid of benzyl salicylate and benzyl benzoate and rich in alkanoic acids but linoleic acid was absent in the oil of the former. However, the orange fowered P. rubra oil contained both the non-terpene esters (benzyl salicylate, benzyl benzoate and 2-phenylethyl benzoate) and alkanoic acids in signifcant amounts. The orange fowered cultivar had the highest concentration of (E)-nerolidol (14.4%) and geraniol (4.1%) among the species studied.
