Abstract: An simple electrochemical pretreatment has been used to active carbon fiber electrodes for in vivo determination.In rat brain, there were four well-defined semi-differential voltammet-ric peaks.The peak at 0.36 Vwas combined by oxidative current of 5-HIAAand UA, 5-HIAAwas about 80% and UAabout 20%.The oxidation of HVAformed the peak at 0.54 V.The concentrations in brain extracellular fluid were determined, 5-HIAA, 3×10-6 mol/L; UA, 9×10-5 mol/Land HVA 8×10-6 mol/L.

Key words: Carbon fiber electrode, Semi-differential voltammetry, Neurotransmitter, Uric acid
