    Abstract:
    Bile acid profiles of bile, urine, and feces obtained from a patient with cerebrotendinous xanthomatosis on the same day have been analyzed by gas-liquid chromatography-mass spectrometry after fractionation into groups by mode of conjugation by an ion-exchange chromatography. The predominant biliary bile acid was cholic acid conjugated with glycine and taurine. Lesser amounts of the amino acid conjugates of chenodeoxycholic acid, ursodeoxycholic acid, 7-ketodeoxycholic acid, allocholic acid, and deoxycholic acid, and of unconjugated norcholic acid and allonorcholic acid were also present in the bile. The major fecal bile acid was 7-epicholic acid. Relatively large amounts of bile acids were excreted in the urine. Unconjugated 7-epicholic acid, norcholic acid, allonorcholic acid, and cholic acid predominated. The bile acid profiles of the patient were different from those of normal subjects and should be useful for the diagnosis.
