Abstract
This study was performed to determine the chemical composition of essential oils from aerial parts with flower of  Helianthemum canum (L.) Baumg. Hydrodistilled essential oil from aerial parts of H. canum was analysed by Gas Chromatography (GC) and Gas Chromatography-Mass Spectrometry (GC/MS).  Fifty-two components were identified representing 94.7% of the oil. Myristicin (29.4%), T-cadinol (6.5%), hexadecanoic acid (5.2%), spathulenol (4.0%) and decanoic acid (3.6%) were the major oil  constituents. To best of our knowledge, this is the first report on the essential oils of  H.canum naturally growing in Turkey.
