Abstract
A micellar electrokinetic chromatography method was developed for the simultaneous determination of dopamine, epinephrine and 5-hydroxytryptamine. Several experimental parameters such as surfactant type and concentration, buffer concentration and pH, type and concentration of organic modifier were evaluated for the analysis of the studied compounds. Among the investigated separation conditions, the composition of micelles, pH and the methanol concentration were the critical parameters. Dopamine, epinephrine and 5-hydroxytryptamine were separated and determined successfully within 7.5 min in Toad venom and Common yam rhizome under the optimum conditions.
