The bile salts of about 30 species of fishes were examined by thin layer chro-matography with the following results.
1. The bile salts of Elasmobranchii consist mainly of scymnol sulfate but also contain tauro-cholate and chimaerol sulfate as minor constituents.
2. Small amount of cholic acid, allo-cholic acid and an unknown bile acid having the same chromatographic behaviour as dihydroxycholanic acid are present in biles of members of the family Cyprinidae, the chief bile salts of which was shown to be 5α-cyprinol sulfate.
3. The main bile constituent of Mis-urgurnus anguillicadatus is 5α-cyprinol sulfate and a little amount of trihydroxycholanic acid conjugated with taurine is also present.
4. Parasilurus asolus bile contains 5α-cyprinol sulfate as a minor constituent in addition to tauro-cholate and tauro-cheno-deoxycholate.
5. Oncorhynchus rhodurus bile contains 3-keto-7α, 12α-dihydroxycholanic acid and cholic acid.
6. In two species of the Class Anguillida, 5β-cyprinol sulfate was shown to be a minor bile component as is the case of Conger myriaster.
7. A new bile acid, haemulcholic acid was isolated from the bile of Parapristipoma trilineatum.
