Identification of (23S)-5 alpha-cholestane-3 alpha,7 alpha,12 alpha,23,25-pentol in urine of patients with cerebrotendinous xanthomatosis.

This paper describes the identification of a new bile alcohol possessing the 5 alpha-cholestane structure that was found in the urine of patients with cerebrotendinous xanthomatosis. The urine samples were extracted with reversed-phase resin, treated with beta-glucuronidase, and separated on silica gel and reversed-phase column chromatography. The new bile alcohol isolated was the second component of the urinary bile alcohols and was identified as (23S)-5 alpha-cholestane-3 alpha,7 alpha,12 alpha,23,25-pentol by means of gas-liquid chromatography/ mass spectrometry and nuclear magnetic resonance spectroscopic studies.[1]
