Protocatechuic acid (= 3,4-dihydroxybenzoic acid; 1) exhibits a significantly slow DPPH (= 2,2diphenyl-1-picrylhydrazyl) radical-scavenging reaction compared to its esters in alcoholic solvents. The present study is aimed at the elucidation of the difference between the radical-scavenging mechanisms

## Abstract Protocatechuic acid esters (= 3,4‐dihydroxybenzoates) scavenge __ca.__ 5β€…equiv. of radical in alcoholic solvents, whereas they consume only 2β€…equiv. of radical in nonalcoholic solvents. While the high radical‐scavenging activity of protocatechuic acid esters in alcoholic solvents as com
