title: Determination of cocaine, benzoylecgonine and ecgonine methyl ester in plasma by reversed-phase high-performance liquid chromatography.
abstract: A combined assay is described for cocaine and its major metabolites, benzoylecgonine and ecgonine methyl ester. The method uses electrochemical and ultraviolet detectors in series. A non-silica column is used with high-pH mobile phase. The three compounds are completely separated from other cocaine metabolites. The assay has been suitable for pharmacokinetic studies of cocaine disposition in animal studies.
