Kihira et al. have found that the principal bile salt of the caecilian, Dermophis mexicanus, is a sulfate ester of 5 8-dermophol, 5y8-cholestane-3a,7a,12a,25,26,27-hexol [6]. 5j8-Dermophol was also found as a minor constituent of the bile of the toad, Bufo vulgaris formosus [6]. 

In 1934, Shimizu and Oda isolated a major bile acid from the toad, Bufo vulgaris formosus, which they named trihydroxybufosterocholenic acid [48]. The structure of this bile acid was elucidated in 1967 by Hoshita et al. as 3a,7a,12a-trihydroxy-... 

A trihydroxycholestenoic acid was isolated as a major bile acid from bile of the toad, Bufo vulgaris formosus [70] and was characterized as (25/ )-3a,7a,12o(-trihy-droxy-5/8-cholest-23-en-26-oic acid by oxidation to 23-norcholic acid and hydrogenation to (25/ )-3a,7a,12a-trihydroxy-5j8-cholestan-26-oic acid [71]. The 5a isomer, 3a,7a,12a-trihydroxy-5a-cholest-23-en-26-oic acid, was recently detected as a minor bile acid in toad bile [46]. The bile of Varanus monitor contains as minor constituents 3a,7a,12a-trihydroxy-5j8-cholest-23- and 24-enoic acids [69]. The acid has been synthesized prior to its detection in nature [72].
