Voltametric determination of melatonin and pyridoxine (vitamin b6) in tablets
item_0042029023.pdf (1.702Kb)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/AgCI in ammonia buffer pH 9 and the peak of melatonin shows an peak potential of 840 mV vs Ag/AgCI in Britton-Robinson buffer pH 2. Both peaks show a linear relation with concentration and consequently are useful for quantification.
