Some water-soluble phenolic acids were investigated as antioxidants, scavengers of hydrogen peroxide (H 2O 2) and scavengers of 1,1-diphenyl-2-picrylhydrazyl radical (DPPH •). The strongest antioxidant, scavenging of H 2O 2 and DPPH • radical activity was exhibited by 3,4,5-trihydroxybenzoic (gallic...
