Abstract
Summary
By criteria of paper chromatography in several systems, ultraviolet and infrared spectrophotometry, 4 pregnene-17 α-ol-3.20, dione has been isolated and identified in adrenal vein blood of normal dogs given adrenocorticotropin intravenously. This steroid could not be detected in blood from the systemic circulation of dogs given adrenocorticotropin.
The authors wish to express gratitude to Dr. Leo T. Samuels for helpful criticism and to Dr. Gunter Zweig, University of California, Pesticide Residue Research, Davis, Cal., for infrared analysis.
