摘要

Herein,an electron spin resonance study on the behavior of organic radicals in fennel before and after irradiation is reported.The spectrum of irradiated fennel composed of the spectrum component derived from the un-irradiated sample(near g=2.005)and the spectra components derived from carbohydrates.The time decay of intensity spectral components was well explained by first-order kinetics with a variety of rate constants.Especially,the signal at near g=2.02 ascribed to stable cellulose-derivative components is expected to be a good indicator in the identification of irradiated plant samples.
