A gas chromatography-mass spectrometric method was established for the determination of karanal in textiles.Karanal in textiles was ultrasonically extracted using methanol as extraction solvent.The extract was then analyzed by gas chromatography-mass spectrometry in selected ion monitoring mode(GC-MS/SIM).The concentration of karanal was calibrated by the external standard method.The limit of detection was 01 mg/kg.Good linearity existed between peak area and the mass concentration of karanal in the range of 014-2818 mg/L.The average recoveries at three spiked levels of 071,282 and 705 mg/kg changed from 873% to 961%.The precision(RSD,n=9) varied from 058% to 24%.The proposed method was simple,accurate,and convenient to operate.It was appropriate for the determination of karanal in textiles in routine tests.
