The parallel relationship between the intensity of visible spectra at 624 nm and ESR signal of hypocrellin A (I) semiquinone radical was established based on the radical anions decay kinetics. The decay characteristics of the semiquinone radical produced by photoredn. of I in the presence of reduced glutathione at different pH were discussed. The intensity of ESR signal of the semiquinone radical increased with increasing pH value.
