摘要：
A new method was developed for the rapid analysis of ochratoxin A (OTA) in pig muscle using dispersive liquid-liquid microextraction (DLLME) combined with high-performance liquid chromatography (HPLC). OTA was extracted with methanol and then cleaned up with DLLME procedure. After being blown dry and redissolved, the sample was determined using high-performance liquid chromatography with fluorescence detector (HPLC-FLD). Under the experimental conditions, the LOD was 0.21 mu g kg(-1), LOQ was 0.70 mu g kg(-1), and the recovery was higher than 80 %. Intra- and inter-day repeatability expressed as RSD were less than 5 %. The established method is more efficient, easier, and cheaper than conventional cleaning up procedure.
