The extraction of EO was done by hydrodistilation using Clevenger aparatus.the gield of EO was 0,18%. The antioxidant activity of EO against DPPH• was moderate comparing with ascarbic acid )vitamine C( whereas, the value of IC50 was 2,27 mg/mL and 0,28 mg/mL and 0,28 mg/mL of ascarbic acid.ArMatricaria pubescens, essential oil, antioxidant activity , The , free-radical DPPH.الجذور الحر ، نبات القريطفة ، الزيوت الأساسيةThesis
