英文摘要
Recently, flow-injection ESR systems for the quantitative spin-trapping ESR measurements have been developed to estimate the second order rate constants (ks) of the reaction between hydroxyl radical and scavengers. The flow-ESR technique is employed for development of a new HPLC-ESR system for the post-column screening of superoxide radical scavengers. This system was composed of a flow UV-irradiation cell for photo-excitation of riboflavin (Rf) to generate superoxide radical in the presence of an appropriate electron donor such as EDTA,. The HPLC- ESR analysis was performed for water soluble components derived from 20 vegetables, such as onion, spinach, cabbage, root radish, etc.
