[Chemiluminescence during oxidation of gossipol by peroxidase].

Gossipol oxidation with peroxidase accompanied by chemiluminescence is revealed. Effect of some factors on chemiluminescence is investigated. Peroxidase gossipol oxidation is suggested to be one of the causes of spontaneous cotton root luminescence. Chemiluminescence in the system studied is inhibited by superoxide dismutase, which indicates the generation of superoxide anion radical. It is suggested that these radicals and other activated oxygen species are involved in the gossipol toxicity for parasitic microorganisms.
