Abstract
1. Preliminary spectroscopic examination of a second component of hagfish bile salts suggested that it might be 3β,7α,26(27)-trihydroxy-5α-cholestane. 2. Impure reduction products of the 3β,26(27)-dihydroxycholestane-7,16-dione previously made from myxinol disulphate appeared also to have the 5α-configuration. 3. Infrared, nuclear-magnetic-resonance and mass-spectrographic as well as optical-rotatory-dispersion measurements on 3β,26(27)-dihydroxycholestane-7,16-dione showed that it was a 5α-compound. 4. Myxinol is thus 3β,7α,16α,26(27)-tetrahydroxy-5α-cholestane; new nuclear-magnetic-resonance measurements on myxinol tetra-acetate at higher resolution confirm this structure.
