Titre : Comparison of the main components of the essential oils of “priprioca” : Cyperus articulatus var. articulatus L., C. articulatus var. nodosus L., C. prolixus kunth and C. rotundus L. Type de document : texte imprimé Auteurs : Maria das G. B. Zoghbi, Auteur ; Eloisa H. A. Andrade, Auteur ; Lea M. M. Carreira, Auteur Année de publication : 2008 Article en page(s) : pp. 42-46 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Cyperus articulatus var. articulatus Cyperus articulatus var. nodosus Cyperus prolixus Cyperus rotundus Cyperaceae Essential oil composition Mustakone Caryophyllene oxide 14-hydroxy-9-epi-(β)-caryophyllene α-cyperone Cyperotundone α-pinene Résumé : The essential oils from the tuber parts of Cyperus articulatus var. articulatus, C. articulatus var nodosus, C. prolixus and C. rotundus cultivated in the State of Pará were obtained by hydrodistillation and analyzed by GC/FID and GC/MS. The oils of C. articulatus var. articulatus and C. articulatus var. nodosus showed mustakone (9.8–14.5% and 6.6–14.5%, respectively) and caryophyllene oxide (4.6–10.8% and 5.4–13.7%, respectively) as major components. The oils of C. prolixus were characterized by a higher amount of caryophyllene oxide (6.9–26.9%), α-cyperone (13.5–20.6%), and 14-hydroxy-9-epi-β-caryophyllene (9.6–16.7%). α-cyperone (22.8%) and cyperotundone (12.1%) were the main compounds from the oil of C. rotundus. The oils of the two varieties of C. articulatus differed from those of the two other species studied here by the presence of mustakone. α-Pinene and β-pinene were higher in the oils of C. articulatus than in those of C. prolixus and C. rotundus. Concerning the two varieties of C. articulatus cultivated in Pará for commercialization in perfumery, we agree that the minor quantitative variations observed in the chemical composition probably do not modify the scent of their oils to any great extent.
