A gas-liquid chromatographic method is described for the determination of testosterone and oestradiol esters in oily injection. The separation of the steroids from the injection is performed by partition in the acetonitrile-hexane system. For gas chromatography the oestradiol esters were preliminary transformed to their mono-TMS derivatives. For the separation Dexsil 400 was preferably used as stationary phase. Mestranol was employed as internal standard for quantitation. A complete separation for all the individual components can be achieved within 12 min. The relative standard deviation is in the range of 1-1.5%. © 1977 Springer-Verlag.
