Abstract:

A method for the determination of 10 prohibited drugs in shampoo by high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) was established. The samples were ultrasonic extracted with methanol, separated on a C18 columm by gradient elution with 0.1% (v/v) formic acid solution and acetonitrile as mobile phases, and finally analyzed using electrospray ionization in positive and negative ion mode with multiple reaction monitoring (MRM). The linear ranges of the 10 compounds were from 0.2 to 10 μg /L with the correlation coefficients (r 2) more than 0.99. The average recoveries and relative standard deviations were 90.5%-94.2% and 2.3%-4.8% respectively in the spiked ranges of 10-50 μg/kg. The limit of detection and quantification were 0.8-2.4 μg/kg and 2.6-7.9 μg/kg, respectively.

Key words: shampoo, HPLC-MS/MS, prohibited drugs, detection
