Chemical Composition and Antioxidant Activity of Essential Oil from Daucus reboudii Coss., an Endemic Plant of Algeria

Plants of the Daucus genus (Apiaceae) are used worldwide as traditional medicines or culinary ingredients. In this work, in order to explore a new chemotype, essential oil obtained from aerial parts reboudii Coss., collected National Park Gouraya (Bejaïa, Algeria), was analyzed by GC-MS. Twenty-eight compounds were identified, accounting for 96.6% total oil. (E)-anethol main constituent (59.4%), followed estragol (21.2%) and dodecanal (4.4%). is an uncommon genus, hence it could be considered marker that contributes differentiating D. other species. Metal chelating, ABTS•+ DPPH• assays performed determine antioxidant activity. The highest activity revealed method, where showed significantly higher compared reference standard BHT at doses 50 100 µg/mL. Results suggest have potential use food industry preservative. Nevertheless, further studies needed assess its applicability, elucidate also composition non-volatile plant.
