The sample was extracted by water and analyzed directly upon concentration. An Agilent ZORBAX SB-C (250 mm 18 ×4.6 mm, 5 µm) column was developed to determine Orange II Dye in Crocus sativus L. samples. The mobile phase was a mixture solution of 0.15% formic acid and methanol. Mass spectrometry was operated in the negative ion mode. Ion fragments m/z 171 and m/z 247 were selected for qualitative analysis. The limit of detection (LOD) is 0.1 mg·L－1. The linear range is 0.5-20 mg·L－1. The average recovery is 100.2 %. The method is applicable for rapid routine monitoring.
