Gas—liquid chromatography and gas chromatography—mass spectrometry have been used to study the pattern of sterols in meconium and faeces from newborn infants. Meconium contained metabolites from various steps in the biosynthesis of cholesterol, e. g. lanosterol, 24, 25-dihydro-∆ 8 -lanosterol, 24, 25-dihydro-∆ 9 -lanosterol, 4 α ,14 α -dimethyl-5 α -cholest-7 (and 8)-en-3 β -ol, 4, 4-dimethyl-5 α -cholest-8-en-3 β -ol, 4, 4-dimethyl-5 α -cholesta-8, 14-dien-3 β -ol and ∆ 7 - and ∆ 8 -methostenol. Meconium and faeces from newborns also contained the sulphate esters of 20, 22-dihydroxycholesterol and of 22-, 23- and 24-hydroxycholesterol.
