Antioxidant activities of 14 commercially available herb teas have been evaluated. Scavenging effects against hypochlorite ion and hydroxyl radical were determined with a method previously proposed by the authors, and expressed as myoglobin protective ratio. The antioxidant activities of the samples were also measured by the widely used DPPH method. In order to characterize the properties of the samples comprehensively, the antioxidant activities against three different radicals were compared in a radar chart. The patterns of the radar charts were similar to that to polyphenols, and the strength of the activity was rated as three ranks. Rose red, peppermint, lemon balm showed strong activity, and chamomile, linden, rosemary, hibiscus, rose hip, and raspberry leaf showed mild antioxidant activity. On the other hand, lemon grass, thyme, lavender, jasmine and erica did not show activity. Although the antioxidant activity of herb tea is strongly depend on the various factors such as origin, preparation methods, their characteristics can be successfully evaluated by the proposed radar chart in quantitative way.
