The present work was identified the chemical composition compounds and compared the various antioxidative activ-ities artemisa persica area parts hydroalcholic extract (AAHE) and artemisia persia arial parts essential oil (AAEO). This experimental study, which carried out in 1391 in Lorestan Medical respectively. Arial parts of arte-misa persica were prepared and then radical scavenging activity, total antioxidant capacity, total phenol and flavo-noid samples was assessed. Also the components of AAEO were analyzed with gas chromatography/mass spectrom-etry (GC/MS). It was demonstrated that total antioxidant capacity AAHE and AAEO is (25.123±5.18; 1.05±0.55) nmol of ascorbic acid equivalents/g extract or essential oil, phenol content (326.68±10.07; 131.14±3) mg of gallic acid equivalents (GAE)/g extract or essential oil, and flavonoid content (6.3±0.94; 1.4±0.65) mg of of quercetin equivalents/g extract or essential oil. Also GC/MS data and retention indices for reference essential oil airial parts samples were used to identify 54 constituents. These compounds make up a total of 70.33 percent essential oil. Al-pha- terpinene; thymol; 3-bromomethyl- 3- oxetanemethanol; 4- ethoxy- tricyclo[5.2.1.0(2, 6)] deca- 3,8 diene- 3-c; nerolidol and phenol are the most of compounds of AAEO. This study showed that artemisa persica has good anti-oxidant properties and artemisa persica is a source easily accessible of natural antioxidants such as alpha-terpinene and thymol and it may be suitable for use in food and pharmaceutical applications.
