The chemical composition of the essential oils of Euphorbia caracasana and E. cotinifolia (Euphorbiaceae) from Venezuela.
The essential oils from leaves of E. caracasana Boiss collected from Miyoi, Pueblo Llano, Mérida State at 1800 m above sea level and leaves of E. cotinifolia L collected from Manzano Alto-Ejido, Mérida State at 1520 m were analyzed by GC/MS. Beta-Caryophyllene (33.7 %), alpha-humulene (18.8 %) and aromadendrene (8.4 %) were the major constituents of E. caracasana oil, whereas those of E. cotinifolia oil were beta-caryophyllene (39.3 %), germacrene-D (21.5 %) and alpha-copaene (9.3 %).
