The composition of the essential oils from leaves of Croton jimenezii Standl. et Valerio, from two locations in Costa Rica were examined and compared. The oils were analyzed by GC/MS. The oil yields were close to 0.1%, and the composition. of the oils were somewhat different for each location. Eighty-nine compounds were identified corresponding to about 95% of the oils. The main constituents of one of the oils were, methyl eugenol (29.5%), germacrene D (15.6%) and beta-caryophyllene (12.9%), whereas hexadecanoic, acid (16.1%), phytol (10.6%), beta-caryophyllene (10.4%) and germacrene D (9.8%) were the main constituents in the other sample.
