摘要: A rapid, simple and effective method for the determination of citrinin in rice by UHPLC coupled to fluorescence detection has been developed validated. Extraction from samples was achieved applying a QuEChERS-based extraction/partitioning process with water acetonitrile, without need further extract clean-up. The fully validated white rice, its applicability other matrices, such as brown red confirmed recovery experiments. Under optimum conditions, recoveries ranged 72.5% 92.8%, relative standard deviations (RSDs) lower than 7.1%. Detection quantification limits were estimated be 1.5 5.0 µg kg−1, respectively. Finally, 21 organic analysed, but none contaminated above limit method. proved fast non-laborious.
