Abstract

In this study, novel magnetic molecularly imprinted polymers (MMIPs) with specific adsorption for glutathione were prepared. Based on MMIPs as adsorbents for magnetic solid-phase extraction, we combined magnetic solid-phase extraction with high-performance liquid chromatography (MPSE-HPLC) for the separation, enrichment, and detection of glutathione in nine kinds of wild edible bolete extracts. MMIPs were characterized by Fourier transform infrared spectrometer (FT-IR), X-ray diffraction (XRD), transmission electron microscopy (TEM), and vibrating sample magnetometer (VSM). In addition, the properties of MMIPs were studied by adsorption isotherm, adsorption kinetic, and selective adsorption experiments. The results showed that MMIPs had high selectivity for glutathione (Kd = 245.33 mL/g), and adsorption time and saturated adsorption capacity were 30 min and 17.88 μmol/g, respectively. Under the optimized conditions, there was a good linear relationship in the concentration range of 100~3000 μg/L, the correlation coefficient R2 = 0.9997, and the limit of detection (LOD) and the limit of quantitation (LOQ) that were 24.828 μg/L and 82.760 μg/L, respectively. The spiked recovery and RSD were 93.28~103.03% and 2.77~5.11, respectively. We successfully combined MSPE-HPLC for the detection of glutathione in nine kinds of wild edible bolete extracts. It was found that the content of glutathione in Leccinum extremiorientale (L. Vass.) Sing. was the highest (19.800 mg/g) and that in Boletus aereus was the lowest (6.791 mg/g).
