Abstract:

Coprostanol and epicholestanol are tow kinds of steroids, and have the same constitutions. Coprostanol, 5β-cholestane-3β-ol, it is a sterol formed exclusively in the gut of man and higher mammals, has been recognized as a good indicator of pollution of water resources by sewage discharge. In order to complete resolution of chromatography peak, coprostanol need to be converted into its corresponding trimethylsilyl derivative. Epicholestanol, 5α-cholestane-3α-ol, was used in oral compositions for periodonted disease control.
