چکیده:

The aerial material of thymus daenensis (t. daenensis) and Lippia citriodora ( l.citriodora) collected from Iran were extracted by hydrodistillation. The chemical composition was analyzed by gaschromatography (GC) and gas chromatography/mass spectrometry (GC/MS). The antioxidative properties and total phenolic contents of L. citriodora and T. daenensis wereexamined. Antioxidant activity of t.daenensis and l.citriodora by two complementary test systems,namely DPPH free radical-scavenging and β-carotene/linoleic acid. Were examined . The antioxidant activity is compared with synthetic antioxidant, namely BHT. The antioxidant activity of t.daenensis ismore than l.citriodora
