摘要:	The electrochemical behaviors of eugenol [1-hydroxy-2-methoxyl-4-allylbenzene] on the gold and platinum electrodes were investigated in a Britton-Robinson buffer (pH 1.60-10.44), acetate buffer, phosphate buffer solutions (pH 2.11 and 3.67) and methanol or acetonitrile containing various supporting electrolytes. The detection cell consisted of a gold wire electrochemical signal obtained with a supporting electrolyte containing 60 % methanol-1.0 mM of potassium dihydrogen phosphate (pH 2.40) as the mobile phase. The limit of quantification of the method was found to be 0.02 ng for eugenol. When eugenol was determined in commercial essential oils and pharmaceutical products with the method proposed the results obtained were comparable with those obtained by high-performance liquid chromatography with ultraviolet detection.
