摘　　要：In this work,the electrochemical behavior of methyl jasmonate(MeJA)on a glassy carbon electrode was investigated in 0.1 mol/L H2SO4 by voltammetry.MeJA exhibited enhanced oxidation behavior in the presence of sodium dodecyl sulfate(SDS). The electrochemical reaction of MeJA on the electrode was carried out with SDS micelles to improve the solubility of MeJA by hydrophobic interaction.Consequently,the oxidation peak current was sensitively enhanced.The effect of experimental parameters on the oxidative peak current was investigated including the surfactant concentration,supporting electrolyte,accumulation potential and time,and scan rate.In this work, the electrochemical behavior of methyl jasmonate （MeJA） on a glassy carbon electrode was investigated in 0.1 mol/L H2SO4 by voltammetry.
