Bile acids. XLIX. Allocholic acid, the major bile acid of Uromastix hardwickii

Abstract

Tauroallocholate is the major bile salt of the lizard, Uromastix hardwickii. Alkaline hydrolysis of bile from 25 gallbladders provided 1.21 g of acidic material, about 90% of which was allocholic acid. Analyses by gas-liquid chromatography, and mass spectrometry verified the presence of almost 10% of deoxycholic acid and smaller amounts of other 5α and 5β-bile acids.
