Abstract

GC and GC-MS analyses of Croton huberi essential oil showed the presence of fourteen compounds, with the major ones being β-caryophyllene (18.3 %) and germacrene-D (16.1 %) while valencene (8.3 %), caryophyllene oxide (7.3 %), bicycle-germacrene (7.1 %) and τ-muurolol (6.1 %) were observed in lower amounts. The oil was characterized by a high percentage of sesquiterpene hydrocarbons 65 %, whereas oxygenated sesquiterpenes represented 21 % and oxygenated monterpenes and diterpenes only 14 % of the total oil.
