The radical scavenging activity (RSA) of 13 kinds of -ray irradiated Kampo extracts were studied by ESR spin-trap method. The RSA against alkoxy radical and hydroxyl radical were measured using new spin trapping reagent CYPMPO. The RSA against these two radicals were evaluated using GSH for alkoxy RSA and L-ascorbic acid for hydroxy RSA as a standard antioxidant reagent. We revealed that a few Kampo extracts showed high RSA against alkoxy radical and hydroxy radical. This RSA of Kampo extracts was changed by -ray irradiation treatment. Using ESR spin-trap method, it is concluded that the effect of radiation treatment on RSA of Kampo extracts were able to detect.

Using Pulse-Electron Spin Resonance (Pulse-ESR) spectroscopy and Continuous Wave-Electron Spin Resonance (CW-ESR) spectroscopy, we revealed the relaxation time (T
, T
) of radicals induced in irradiated foods. The relaxation time was directly analyzed by Pulse-ESR. Using CW-ESR, the relaxation time was calculated by the measured spectrum parameter indirectly. We succeeded in the detection of Pulse-ESR signal of irradiated hard wheat flour and irradiated black pepper. It was suggested that using CW-ESR T and T can be calculated effectively, but the value was tend to slightly lower due to the parameters for calculation are affected by the contents of food especially protein.
