Essential oils from fresh flowers and stems of Crassocephalum sp (Asteraceae) growing wild in Côte d'Ivoire were extracted by hydrodistillation using a Clevenger-type apparatus. Essential oils were analyzed by Gas Chromatography (GC) and then by GC coupled with a Mass Spectrometry (GC-MS). The analyzes of the oils allowed the identification and quantification of 39 and 83 constituents respectively in the oils of the flowers and the stems. The characterization of the oils revealed the predominance of the hydrocarbon monoterpene myrcene with 87.25% in the flowers, 35.55% in the stems. Myrcene alone accounts for almost all of the flower oil. The chemotype of the stem oils is different from that of the flowers with the presence of terpinolene (31.99%) and (E)-dec-2-enal (8.01%) which are other major compounds in the oils of the stems of Crassocephalum sp
