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.
