Abstract:

The antioxidant effects of the essential oils from four species of aromatic plants cultivated in Xinjiang, Rose rugosa Thumb., Rosmarinus officinalis L., Mentha piperita L. and Chamaemelum nobile L., were assessed and compared by measuring their DPPH, hydroxyl and superoxide anion free radical scavenging capacities and their inhibitory effect on lipid peroxidation in a triobarbituric acid (TBA) reaction system. The four essential oils were all able to scavenge DPPH, hydroxyl and superoxide anion free radicals and inhibit the peroxidation of unsaturated fatty acids in egg yolk in a positive concentration-dependent fashion. Rose oil had the most excellent antioxidant activity, followed by rosemary oil, peppermint oil and roman chamomile oil.

Key words: Xinjiang;Rose rugosa Thumb., Rosmarinus officinalis L., Mentha piperita L., Chamaemelum nobile L., volatile oil, antioxidant
