The Isolation of Steroid Conjugates,e from human urine in 1944 [5]. Nevertheless, as recently as 1953 only 4 intact steroid sulfates and 3 glucuronides had been isolated from urine and fully characterized, while none had yet been obtained from other sources such as plasma or bile. On the other hand, approximately 150 free steroids had

Pregnanediol glucuronide was regarded as the conjugated water-soluble form in which large amounts of the steroid were excreted in the urine. This was the traditional physiologic role assigned to all steroid conjugates.

These investigators noted that acidification of male urine to pH 4.0–4.5 and continuous extraction with chloroform led to an enhancement of the biological activity of the extract. This observation was confirmed by Kabak in 1931 [2] and by Adle
