Abstract
Anodic oxidation of coumaric acid led to the inhibition of the process at the electrode due to a film which was formed after one-electron oxidation of the acid to phenoxy radical.By contrast, caffeic acid is oxidized in two steps-the phenoxy radical is formed in the first step, quinone in the second step. The inhibition of nitrate uptake by coumaric and caffeic acids is dependent on their concentration. 10-4 M eaffeic acid totally inhibited nitrate uptake and the growth ofNicotiana tabacum cell suspension. 10-6 M caffeic acid markedly inhibited nitrate uptake especially in the first three days after inoculation. 10-6 M coumaric acid did not affect nitrate uptake and nitrate reductase activity, 10-4 M coumaric acid inhibited nitrate uptake by day two after inoculation. Nitrate reductase synthesis correlated with the inhibition of nitrate uptake. Differential effects of coumaric and caffeic acids are explained on the basis of different products of their electrochemical oxidation.
