title: Analysis of steroids Part 50. Derivatization of ketosteroids for their separation and determination by capillary electrophoresis.
abstract: 4-Ene-3-ketosteroids and 17-ketosteroids were quantitatively transformed into the corresponding hydrazones using Girard P and T reagents, respectively. The positively charged derivatives were separated by capillary electrophoresis. The spectrophotometric characteristics of the derivatives permitted their sensitive detection in the 230-280 nm range. The steroids investigated included nortestosterone and its phenylpropionate, norethisterone and its oenanthate, d,l-norgestrel, dehydroepiandrosterone, androstenedione and ethisterone.
