title: Identification of new C27 and C24 bile acids in the bile of Alligator mississippiensis.
abstract: Biliary bile acids of Alligator mississippiensis were analyzed by gas-liquid chromatography-mass spectrometry after fractionation by silica gel column chromatography. It was shown that the alligator bile contained 12 C27 bile acids and 8 C24 bile acids. In addition to the C27 bile acids, such as 3 alpha,7 alpha,12 alpha-trihydroxy-5 beta-cholestanoic acid, 3 alpha,7 alpha,12 alpha-trihydroxy-5 alpha-cholestanoic acid, 3 alpha,7 alpha-dihydroxy-5 beta-cholestanoic acid, 3 alpha,12 alpha-dihydroxy-5 beta-cholestanoic acid, 7 alpha,12 alpha-dihydroxy-3-oxo-5 beta-cholestanoic acid, and 3 alpha,12 alpha-dihydroxy-7-oxo-5 beta-cholestanoic acid, identified previously in the bile of A. mississippiensis, 3 alpha,7 beta-dihydroxy-5 beta-cholestanoic acid, 3 alpha,7 beta,12 alpha-trihydroxy-5 beta-cholestanoic acid, 7 beta,12 alpha-dihydroxy-3-oxo-5 beta-cholestanoic acid, 3 alpha,7 alpha,12 alpha,24-tetrahydroxy-5 beta-cholestanoic acid, 3 alpha,7 alpha,12 alpha,26-tetrahydroxy-5 beta-cholestanoic acid, and 1 beta,3 alpha,7 alpha,12 alpha-tetrahydroxy-5 beta-cholestanoic acid were newly identified. And in addition to the C24 bile acids, such as chenodeoxycholic acid, ursodeoxycholic acid, cholic acid, and allocholic acid, identified previously, deoxycholic acid, 3 alpha,7 alpha-dihydroxy-5 beta-chol-22-enoic acid, 3 alpha,7 alpha,12 alpha-trihydroxy-5 alpha-chol-22-enoic acid, and 3 alpha,7 alpha,12 alpha-trihydroxy-5 beta-chol-22-enoic acid were newly identified.
