Identification of acidic steroids in feces of monkeys fed beta-sitoserol.
Vervet monkeys were fed a suspension of beta-sitoseterol in corn oil. Acidic steroids were separated from a 4-day pool of feces and subjected, after fractionation, to gas liquid chromatography and mass spectrometry. Evidence for the presence of derivatives of 27-carboxysitosterol, 27-carboxysitostanol and 7-hydroxy, 27-carboxysitostanol is adduced.
