Less-volatile organic components in leaves from aromatic tobaccos of different varieties, both Oriental and Korean types were isolated and concentrated using a simple apparatus with fewer manipulations. Each less-volatile concentrate was then subjected to spectrophotometric recording in the visible range, to thin-layer chromatographic group separation, and high-performance liquid chromatographic profile analysis. The methods allow detection of significant quantitative differences in visible absorption spectra, TLC patterns, and high resolution HPLC profiles among varieties.
