中文摘要：本研究提出了一种快速、简便且易于操作的富集、提取大米样品中的脱氧雪腐镰刀菌烯醇(DON)的空气辅助分散液-液微萃取(AA-DLLME)法并与固相萃取（SPE）净化进行比较。研究发现两种方法都可用于提取大米中的DON。
外文摘要：A fast, simple, and easy to operate air assisted-dispersive liquid-liquid microextraction (AA-DLLME) for preconcentration and extraction of deoxynivalenol (DON) from rice samples is proposed and compared with solid phase extraction (SPE) cleanup. DON was determined using a high performance liquid chromatography with diode-array detection (HPLC-DAD). AA-DLLME was performed using a glass syringe and dispersion of extractant in the sample solution was achieved with help of air bubbles. Chloroform was used as the extractant solvent. To find out the optimized condition for the proposed method, response surface methodology (RSM) was applied for multivariate optimization of effecting parameters namely volume of extractant, number of extraction, pH, and rate of centrifugation. Under optimized condition the dynamic range of calibration graph was found to be 50–500 μg L−1 with detection limit of 23.6 μg L−1. Both methods were applied for extraction of DON from rice.
