The estimation of a fraction resembling pregnanediol glucuronide in human urine

Abstract
A method of estimating pregnanediol glucuronidate by entrain-ment on Ba phosphate and subsequent application of a modified naphthoresorcinol reaction was developed. The method when applied to urine gives analytical figures for a glucuronide fraction, ''pregnanediol-like glucuronide (PLG)''. Minimal figures for PLG (as NaPG) in various urines, including those of the human menstrual cycle, are reported.
