L. Valvo et al., GENERAL HIGH-PERFORMANCE LIQUID-CHROMATOGRAPHIC PROCEDURES FOR THE RAPID SCREENING OF NATURAL AND SYNTHETIC CORTICOSTEROIDS, Journal of pharmaceutical and biomedical analysis, 12(6), 1994, pp. 805-810
A study of a multiple high-performance liquid chromatographic procedur
e for the separation of 30 different corticosteroids is described. Nor
mal- and reversed-phase general methods operating in a wide polarity r
ange have been developed for the rapid screening of multicomponent mix
tures. The complementary application of both normal- and reversed-phas
e methods could permit clarification of uncertainty deriving from anal
yses performed by only one method.
