✦ Synopsis

A new method for the analysis of anabohc hormones by reversed-phase liquid chromatography coupled with electrochenucal detection has been developed Testosterone and androsterone were denvatlzed Into corresponding sabcyhc estem by treatment Hnth sahcyhc acid chlonde m the presence of 18-crown-6 and potassmm carbonate as catalysts Before derlvatlzatlon, plasma and unne samples of the hormones were precleaned by sohd-phase extraction usmg also reversed-phase matenal as a stationary phase The denvatwes were separated from the excess of reagent by column swtchmg and were momtored amperometncally at 1000 mV vs palladium m the oxldatlve mode Keyworak Liquid chromatography, Anabohc steroids, Androsterone, Pre-column denvatlzatlon, Plasma, Unne, Testosterone
