In a thorough analysis of solvolyzed material from bullfrog bile. Noma et al. isolated 4 new Cjj bile alcohols along with 5a-ranol, 5)3-ranol, and 5a-cyprinol [41]. Comparison with synthetic samples showed that these were 4 diastereoisomers at C-5 and C-24 of 26-deoxyranol, 27-norcholestane-3a,7a,12a,24-tetrol [41]. The... [Pg.284]

Noma et al. found 2 keto bile alcohols in unconjugated form in bullfrog bile [42]. Their structures were determined as 24-dehydro-26-deoxy-5a-ranol and its 5 isomer by comparison with synthetic 3a,7a,12a-trihydroxy-27-nor-5a- and 5/8-choles-tan-24-ones, prepared from allocholic acid and chohc acid, respectively [41]. [Pg.285]

Nor-26-deoxy-5a- and 5j8-ranols, 26,27-dinor-5a- and 5j8-cholestane-3a,7a,12a,24-tetrols, were detected by gas-liquid chromatography-mass spectrometry as minor constituents in the bile of a few species of frogs [9]. [Pg.285]
