- W1988045368 abstract "Recent studies of Zimmermann (1, 2) and Oesting (3) have shown that the active R-CO-CH2 grouping of the sex hormones reacts with m-dinitrobenzene to yield a chromogen which can be measured colorimetrically. Thus, estrone, progesterone, androsterone and pregnandione produce various colors by this reaction; the androsterone yields a violet color. Subsequently, Oesting (3) has modified the method for colorimetric measurement and reports his results as color units. Oesting (3), and Oesting and Webster (4) found a satisfactory relationship between the colorimetric assay and the comb-growth method in capons. It is unnecessary to emphasize the advantages for clinical purposes of having an exact physicochemical method for the quantitative determination of the sex hormones instead of the more laborious and time-consuming biological methods. It is the purpose of this communication to present a physicochemical study of the color reaction of androsterone with m-dinitrobenzene and a quantitatively reliable method." @default.
