HPTLC screening assay for urinary cotinine as biomarker of environmental tobacco smoke exposure among male adolescents.

For selective screening determination of urinary cotinine, i.e. (S)-1-methyl-5-(3-pyridyl)-2-pyrrolidinone, the major metabolite of nicotine, the high-performance thin-layer chromatographic (HPTLC) method have been proposed.
