Comparative analysis of ephedrine derivative content in 96 urine specimen obtained from people suspected in abuse with these drugs. Physical and chemical methods of the analysis (gas and thin-layer chromatography) as well as ELISA were used. It was stated that the latter is specific for determination of compounds related to ephedrine by structure and it allows one to detect its analogues in 87 cases. Gas chromatography made it possible to detect ephedrine derivatives in 94 specimen tested and thin-layer chromatography--in 64 specimen tested. The given ELISA may be recommended for medicolegal expert purposes and narcology practice.
Competitive ELISA method for ephedrine assay in biological fluids is developed. Anti-ephedrine antibodies obtained by rabbit immunization with conjugated antigen ephedrine-protein and ephedrine complex with horseradish peroxidase were used as reagents. ELISA in combination with chromatographic methods may be used in medicolegal and narcological practice.
