✦ Synopsis

Pseudoecgonine was detected and resolved from ecgonine in illicit cocaine samples by narrow bore capillary gas chromatography (CGCl at levels of less than 0.1%. Identification and confirmation was supported by gas chromatography mass spectroscopy (GCMS), infrared spectroscopy (IR), and nuclear magnetic resonance (NMR). Its presence in illicit cocaine samples is examined as an indicator for comparing drug seizures believed to be of common origin.
