SUMMARY A new chromatographic procedure for determining small amounts of
pregnanediol in urine is described. The method involves (1) acid hydrolysis,(2) toluene …

A method is described for the assay of urinary pregnanediol and allopregnanediol which
employs acid hydrolysis of pregnanediol glucuronide, ascending thin-layer chromatography …

A method suitable for the routine determination of urinary pregnanediol and pregnanetriol
has been devised. It involves glucuronidase hydrolysis, extraction, and chromatography on …
