Nuclear-magnetic-resonance and mass-spectral examination of the principal bile alcohol from Catostomus commersoni and its anhydro derivative.

ABSTRACT: On the basis of i.r. and chromatographic evidence 5alpha-cholestane-3alpha,7alpha,12alpha,24xi,26-pentol(I) and 24xi,26-oxido-5alpha-cholestane-3alpha,7alpha,12alpha-triol (IV) structures have been proposed for the principal cleavage and alkaline-hydrolysis products of the bile salts from Catostomus commersoni (Anderson & Haslewood, 1969). N.m.r.- and mass-spectral analyses of these substances and the tetra- (II) and penta-acetate (III) derivatives of (I) provided supporting evidence for the structural assignments.
