| Outline of Final Research Achievements |
Recently, we have developed flow-injection-ESR and HPLC-ESR systems special for quantitative spin-trapping ESR detection of the superoxide radical by using DMPO, as a spin-trapping reagent. The flow-ESR techniques were employed to explore potent superoxide radical scavengers involved in foods. In the present study, HPLC-ESR measurements were made for water-soluble components of foods. The determination of antioxidant activity was calculated using ESR line simulation.
