Rapid Detection Of Alternaria Monomethyl Ether In Wheat By High Performance Liquid Chromatography, Xu Qun-Ying, Zhai Yu-Heng

Food and Machinery

In this study, a high-performance liquid chromatography (HPLC) method for the efficient detection of alternariolmethyl ether (AME) in wheat was developed. The sample was extracted with acetonitrile/ methanol/ water (volume ratio 45/10/45), shaken at 30 ℃ for 30 minutes, and purified by Bond Elut Plexa solid-phase extraction cartridge. Then the sample was detected with a Variable wavelength detector. In this method, the limit of detection (LOD) of AME was 2.52 μg/kg, and the limit of quantification (LOQ) was 8.40 μg/kg, and the linear range was 0.25~2.00 μg/mL. The concentration of AME recovery was 80.1%~88.3%, the intra-day precision and inter-day precision …
