High-performance liquid chromatography of steroidal drugs.

The high-performance liquid chromatographic (HPLC) analysis of progesterone, oxyprogesterone capronate and dehydroacetoxyprogesterone has been carried out successfully using so-called "test impurities". The quantitative and qualitative analysis of related compounds was studied by normal-phase HPLC with a UV detector (254 nm) using ethyl acetate-chloroform (98.5:1.
