DFT methods including B3LYP, B3PW91 and M05–2x associated to 6–31+G(d,p) were used for the structural and antioxidant potency studies of phenylethyl-3,4-dihydroxy-hydrocinnamate (PDH). Solvents were employed according to their protric and aprotic character. So, calculated structures agree with the experimental data. O4H4 is propitious to scavenge radicals whatever the medium except in water where...
