Catalytic Oxidation and Antioxidant Properties of Thyme Essential Oils (Thymus vulgarae L.)

Year: 2005

Type: article

Abstract: The antioxidant properties of two chemotypes of thyme essential oils were examined in relation to their catalytic transformation. Catalytic oxidations were performed with potassium hydrogentrioxoperoxosulfate(VI) and the Fe I I I meso-tetraphenylporphyrin catalytic system, after which the chemical compositions of essential oils were changed. The antioxidant activity was investigated by two different methods: the 2,2'-diphenyl-1-picrylhydrazyl radical scavenging method and the Ferric Reducing / Antioxidant Power assay. Both methods have shown that the phenolic chemotype possesses stronger antioxidant properties than the non-phenolic one. After catalytic oxidation, the essential oils of both chemotypes showed stronger antioxidant effects than before oxidation.
