title: Identification of 20 alpha-hydroxy-5 alpha-pregnan-3-one and 20 beta-hydroxy-5 alpha-pregnan-3-one in human pregnancy urine.
abstract: 20 beta-Hydroxy-5 alpha-pregnan-3-one and 20 alpha-hydroxy-5 alpha-pregnan-3-one were isolated and identified from a pool of urine collected from women in the third trimester of pregnancy. Following isolation by Sephadex LH-20 and HPLC, the identity of each compound was established by comparison of GC-MS data for the methyloxime-trimethylsilyl ethers with those for authentic standards.
