  • Title: Simultaneous determination of anabolic and catabolic steroid hormones in meat by gas chromatography-mass spectrometry.
    Author: Hartmann S, Steinhart H.
    Journal: J Chromatogr B Biomed Sci Appl; 1997 Dec 19; 704(1-2):105-17. PubMed ID: 9518140.
    Abstract:
    A rapid and economical method for the determination in meat of androgens, estrogens, progestogens and corticoids, including some precursors and metabolites, has been developed. The extracted steroids are separated in a polar, a neutral, and a phenolic fraction by C8-SPE followed by a liquid-liquid extraction of the phenolates. Each fraction is separately purified by normal-phase SPE. The different steroid fractions can be analysed either together to obtain a comprehensive hormone pattern in one step or separately to enhance detection selectivity and sensitivity. Using a universally applicable silylation of the hydroxyl and keto groups, detection limits of 0.02-0.1 microg/kg are reached by GC-MS (EI) in the selected ion monitoring mode.
