Abstract:

Melatonin, N-acetyl-5-methoxytryptamine, is an indoleamine hormone synthesized in the pinealocytes. It has been considered as a time-keeping hormone at the biological clocks and was found to play central role in cell protection[1]. Melatonin in biological samples can be detected by several methods, such as HPLC, UV, fluorimetry and radio-immunoassay. However, only a few studies dealing with its redox behavior have been reported[1-3]. The aim of the present study is to use the activating electrochemical modified glassy carbon electrode(MGCE) for the preconcentration and trace determination of melatonin.
