Abstract

The steroid glucuronide, and mono- and disulphate fractions were obtained from human bile by chromatography on Sephadex LH-20. The conjugates in the glucuronide fraction were hyderolysed with β-glucuronidase and the mono- and disulphate fractions were solvolysed. The steroids liberated were fractionated on silicic acid and by thin layer chromatography and analysed by gas-liquid chromatography and gas chromatography-mass spectrometry. The following C21O3 and C21O4 steroids were identified: 5α-pregnane-3α,17α,20α-triol, 5β-pregnane-3α,17α,20α-triol, 5-pregnene-3α,17α,20α-triol, 5-pregnene-3β,17α,20α-triol, 5α-pregnane-3α,16α,20α-triol, 3α,21-dihydroxy-5β-pregnan-20-one, 3α,11β,21-trihydroxy-5α-pregnan-20-one, 3α,11β,21-trihydroxy-5β-pregnan-20-one and 3α,21-dihydroxy-5β-pregnane-11,20-dione. Concentrations of these steroids were measured in fistula or gall-bladder bile samples from five subjects.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
