New sodium bile alcohol sulfates were obtained from the bile of megamouth shark by chromatography on silica gel and Sephadex LH-20, together with two sodium scymnol sulfates, (24R,25S)- and (24R,25R)- (+)3α,7α,12α,24,26-pentahydroxy-5β-cholestan-27-yl sodium sulfate (2 and 3). On hydrolysis in pyridine-dioxane, the new salts afforded a new bile alcohol (1), whose structure was determined to be (24R)-5β-cholestane- 3α,12α,24,26,27-pentol, based on chemical and spectral data. On the basis of the physicochemical data, the new salts were established as (24R,25S)- and (24R,25R)-(+)-3α,12α,24,26-tetrahydroxy-5β-cholestan-27-yl sodium sulfate.
