Sažetak

The Pale Yellow (PY) Naphthalan is potentially a new treatment modality for some oral mucosal
and dermatological diseases. Its chemical composition and physical properties were studied by standard
and sophisticated methods. Special attention was paid to steranes and hopanes as favorable components
and to aromatics as unfavorable compounds. PY Naphthalan is predominantly composed of saturated aliphatic
hydrocarbons of different structures, and of hydrocarbons comprising aromatic ring(s) (< 15%).
Among aromatics, 98% were monoaromatics and 2% diaromatics, while 16 polycyclic aromatic hydrocarbons
designated by US Environmental Protection Agency as priority pollutants were found at minimum
detectability levels. Steranes and hopanes appeared in native geogenic clusters of homologs and
each of identified compounds was in native geogenic configuration. Steranes were in the range from norcholestanes
up to propyl cholestanes and hopanes up to pentakishomohopanes. The content of steranes
and hopanes was relatively high. Compared to the other naphthalan products, the composition of PY
Naphthalan is remarkably improved. Physical properties make PY Naphthalan convenient for application.
