Bile salts of ten species of frogs of the family Ranidae were examined by
means of thin-layer chromatography, gas-liquid chromatography, and
gas-liquid chromatography-mass spectrometry. Their major bile alcohols were
ranol, cyprinol, or bufol. Four species of frogs contained lesser amounts
of higher bile acids, and in two species C24 bile acids were present. A
higher bile acid that has not been previously described was detected in
Rana plancyi. On the basis of the spectral data and the direct comparison
with a synthetic sample, the chemical structure of the new bile acid was
established to be 3 alpha, 7 alpha, 12 alpha, 26- tetrahydroxy-5
beta-cholestanoic acid.
