Abstract:

In this study, solid phase extraction was used in pretreatment. After separated by HPLC with acetronitrile-ammonium acetate buffer as mobile phase, malachite green (MG) and leucomalachite green (LMG) in foods were detected by MSD in the ESI(+)-SIM mode. This analytical approach is highly sensitive, rapid and precise, therefore it has enormous application value.

Key words: malachite green, leucomalachite green, HPLC/MS, aquatic
