<div><p>This study reports the chemical composition, antioxidant and anti-inflammatory properties of <i>Anethum graveolens</i> essential oil and its main compounds. The essential oil was obtained from the aerial parts of the plant by hydrodistillation and analysed by using GC/MS. α-Phellandrene (19.12%), limonene (26.34%), dill ether (15.23%), sabinene (11.34%), α-pinene (2%), <i>n</i>-tetracosane (1.54%), neophytadiene (1.43%), <i>n</i>-docosane (1.04), <i>n</i>-tricosane (1%), <i>n</i>-nonadecane (1%), <i>n</i>-eicosane (0.78%), <i>n</i>-heneicosane (0.67%), β-myrcene (0.23%) and α-tujene (0.21%) were found to be the major constituents of the oil. <i>A. graveolens</i> oil exhibit a higher activity in each antioxidant system with a special attention for β-carotene bleaching test (IC<sub>50</sub>: 15.3 μg/mL) and reducing power (EC<sub>50</sub>: 11.24 μg/mL). The TLC-bioautography screening and fractionation resulted in the separation of the main antioxidant compounds, which were identified as limonene (45%) and sabinene (32%). The essential oil and its main compounds exhibited a potent NO-scavenging effect and inhibited the expression of inducible NO synthase.</p></div>
