    Description: A supramolecular solvent composed of decanol in tetrahydrofuran/water was utilized for the simultaneous microextraction of chiral triadimefon and triadimenol in beer samples. Supramolecular solvents are nanostructured amphiphilic liquids that contain aqueous cavities, and the size of those cavities can be adjusted by the ratio of decanol, tetrahydrofuran, and water. The target analytes were mixed into the matrix sample and extracted in the supramolecular solvent phase, which was followed by separation and quantification by chiral liquid chromatography-mass spectrometry. The influences of some analytical parameters and matrix components were all examined. Under the optimized conditions, the method detection limits were in the range of 0.24 to 0.98 μg L −1 (at a signal/noise of 3), with relative standard deviations between 1.6 and 5.7%. The linearities of the calibration plots were between 0.5 to 50 (triadimenol) and 1.0 to 100 μg L −1 (triadimefon). When this method was applied to a spiked beer sample, the recoveries ranged from 84 to 100%.
