Description of a Harmless Method for Determining Trenbolone Acetate Together with 17β-Trenbolone in Beef

The simultaneous detection of trenbolone acetate and 17-trenbolone in cattle muscle is described using a cost-effective, safe, and quick sample preparation method followed by reversed-phase high-performance liquid chromatography (HPLC). On a short C1 column with an isocratic mobile phase, HPLC analysis with a photo-diode array detector was performed. Analyses of spiked samples, resulting recoveries (87.9%; relative standard deviations 3.4%), analytical total time (20 min/sample, where a batch of 12 samples was finished in 2 hours), and quantitation limits (1.8 ng/g) were used to verify the method. The proposed method for detecting TBa and -TB in beef (cattle muscle) is a valuable tool for routine residue monitoring in beef as well as beef farm withdrawal control. There were no hazardous organic solvents or reagents employed at all.
