Abstract:
A novel and sensitive deep eutectic solvent-based matrix solid phase dispersion (DES-MSPD) method for the determination of aflatoxins (AFB1, AFB2, AFG1, AFG2) in various crops was established using high-performance liquid chromatography with fluorescence detection (HPLC-FLD). The DES-MSPD sample preparation procedure was optimized. Based on the optimal conditions, the intra-day and inter-day variability for AFs in all crop samples was less than 7.5%. Linearity was observed with R2 values (>0.994). Using the present method, HPLC-FLD gave the limits of detection (LODs) of 0.03-0.10 μg/kg and the limits of quantification (LOQs) of 0.10-0.33 μg/kg for AFs. This work represents the first attempt of using DESs as a green extraction medium for the extraction of AFs in MSPD. Compared with conventional MSPD methods, the DES-MSPD procedure looks promising as a relatively simple and low cost process to build an assay that can be used for monitoring concentrations of AFs in crops.

Molecular Solids
Molecular crystalline solids, such as ice, sucrose (table sugar), and iodine, are solids that are composed of neutral molecules as their constituent units. These molecules are held together by weak intermolecular forces such as London dispersion forces, dipole-dipole interactions, or hydrogen bonds, which...
