A liquid chromatographic procedure is described for the analysis of illicit cocaine samples. The isomeric cis- and trans-cinnamoylcocaines are separated from cocaine, benzoylecgonine, and benzoic acid in a reverse phase isocratic system with dual wavelength detection at 254 and 280 nm. Specific identification of cocaine and the cinnamoylcocaines is accomplished by ultraviolet spectrophotometry and mass spectrometry of the chromatographic effluent.
