Electrochemical oxidation of ethanolic leaves and flowers extract of phlomis olivieri have been studied in the absence and presence the aqueous solution of barbituric acid at the biological pH, using cyclic voltammetry method. The results showed that the electrochemically generated compounds in leaves and flowers extract of phlomis olivieri, participate in the chemical reaction with barbituric acid. Based on our results, leaves and flowers extract of phlomis olivieri have a high antioxidant activity in comparison of galic acid, salicylic acid and quercetin as standard antioxidants and simultaneous can be useful for the treatment of barbiturate poisoning before starting clinical treatments.
