Abstract: Thapsia garganica is a medicinal plant belonging to the Apiaceae family, commonly known in Algeria as Derias. This plant contains several bioactive compounds, some of which may have antioxidant properties. The Antioxidant activity of essential oils of Thapsia garganica, using the powder of aerial parts can be evaluated with DPPH (2,2-diphenyl-1-picrylhydrazyl) test. DPPH is a free radical that has a dark purple color in solution. When it reacts with antioxidants, it loses an electron, and its purple color disappears, indicating its antioxidant power. It was comparing with Ascorbic acid or vitamin C as a reference. The findings from the antioxidant activity analysis revealed that the plant being studied demonstrated a high activity, showing an inhibition percentage (I) of 78.3% when compared to Ascorbic acid as control, which exhibited 82.17% inhibition at the highest concentration, which means a good antioxidant activity of this plant.
