A new ultra-high performance liquid chromatographic method was developed for analysis of five banned rhodamine B,malachite green,crystal violet and their metabolites residues in meat.The meat samples were extracted by microwave-assisted extraction with methanol-water(95∶5,V/V),followed by clean up with C18 solid phase extraction column.The effective separation of five colorants in meat matrixes was achieved using ACQUITY BEH C18 analytical column with acetonitrile-20 mmol/L acetic ammonium buffer(80∶20,V/V,...
