Chemical Composition of Essential Oils and Hydrosol Extracts of Daucus muricatus and Assessment of Its Antioxidant Activity

International audience; A comparative study of volatile compounds from Daucus muricatus obtained by hydrodistillation and liquid–liquid extraction by GC and gas chromatography mass spectroscopy (GCMS) was conducted. The essential oils extracted from roots were mainly composed of aliphatic compounds while oils extracted from aerial part were characterized by monoterpene hydrocarbons. However, the GCMS analyses of composition hydrosol extracts shows only oxygenated compounds; no hydrocarbons were noted. The antioxidant activity of the hydrosol extracts exhibited the high antioxidant activity with IC50 value of 50.08 and 63.05 μg.mL−1 for roots and aerial parts, respectively, better than from synthetic antioxidant BHT (103.98 μg.mL−1).
