Abstract	dc.description.abstract	Melatonin and Vitamin B6 can be oxidized at the glassy carbon electrode showing well-resolved anodic peaks by differential pulse voltammetry. Vitamin B6 shows an oxidation peak potential of about 650 mV vs Ag/AgCl in ammonia buffer pH 9 and the peak of melatonin shows an peak potential of 840 mV vs Ag/AgCl in Britton-Robinson buffer pH 2. Both peaks show a linear relation with concentration and consequently are useful for quantification.	en
