Determination of Hormone Residues in Imported and Exported Food Animals
Liquid chromatography-mass spectrometry/mass spectrometry
1 Scope
The current standard specifies liquid chromatography-mass spectrometry/mass spectrometry detection methods for the determination of androgens, progestogens and estrogen residues in edible animals for import and export.
This standard applies to food animals, beef, sheep, pig serum and urine androgen in food and poultry inspection and quarantine work (Trenbolone, bupropion, and male
Dione, nandrolone, metoprolone, testosterone, methyltestosterone, stanozolol), progestogen (norethindrone, 21α-hydroxyprogesterone, 17α-hydroxyprogesterone, norgestrel, methylol
Progesterone, megestrol acetate, chlorprogesterone acetate, medroxyprogesterone acetate, progesterone) and estrogen (estriol, estradiol, estrone, diethylstilbestrol,
Dienestilbestrol and estradiol were measured.
2 Method summary
The target compound in the sample was subjected to enzymatic hydrolysis overnight, methanol solution extraction, graphite carbon black column-amino column tandem enrichment and purification, liquid chromatography-string
Mass spectrometer measurement, internal standard method quantification.
