摘要：

The reaction between phenol, dihydroxyfumaric acid and oxygen was studied in the presence of horseradish peroxidase. The use of a sensitive HPLC method enables detection of three products of hydroxylation: catechol, hydroquinone and 1,2,4-benzenetriol. Influence of various parameters indicates that the enzyme catalyses the autooxidation of DHF. The formation of compound Ill is a consequence of superoxide anion present in excess in the solution. However, this compound is not involved in the catalysis of formation of the .OH radicals.
