Abstract
New sodium bile alcohol sulfates (1a and 1b), two sodium cyprinol sulfates (2a and 2b), and the sodium salt of a new bile acid conjugated with taurine (3) were isolated from the bile of sunfish, Mola mola L., by chromatography on silica gel and octadecylsilane (ODS), together with sodium taurocholate (4). On hydrolysis with pyridine and dioxane, the new sulfates 1a and 1b both afforded a new bile alcohol (5), whose structure was determined to be 5β-cholestane-3α, 7, α11α, 26, 27-pentol, based on the physico-chemical data. On the basis of this result and their physiochemical data, the new sulfates were established as (25S)- and (25R)-(+)-3α, 7α, 11α, 26-tetrahydroxy-5β-cholestan-27-yl sodium sulfate. Based on the physicochemical data and chemical transformations, the sodium cyprinol sulfates were identified as (25S)- and (25R)-(+)-3α, 7α, 12α, 26-tetrahydroxy-5β-cholestan-27-yl sodium sulfate and compound 3 as sodium 2-[[3α, 7α, 11α-trihydroxy-24-oxo-5β-cholan-24-yl]amino]ethanesulfonate.
