Determination of Resveratrol in Peanut Root Using Molecularly Imprinted Polymers Multiplug Filtration Clean up Column Coupled with Fluorescence Spectrometry
New molecularly imprinted polymers(MIPs) were prepared by using attapulgite(ATP) as the support,β-CD and methacrylic acid(MAA) as functional monomer,resveratrol as template molecule through surface molecularly imprinted polymerization technology.The MIPs were used as sorbent filled into the multiplug filtration clean-up(m-PFC) column for resveratrol enrichment and purification.A new method was developed for the determination of resveratrol by using multiplug filtration clean-up column with molecularly imprinted polymers extraction(MIPs-m-PFCE) combined with fluorescence spectrometry.The results showed that the present method has a high selectivity for RES under the optimized experimental conditions,the adsorption capacity of MIPs was 12.78 mg/g.The calibration curve was linear in the range of 0.1-100 μg/mL with a correlation coefficient(r) of 0.999 7.The limit of detection was 0.048 μg/L.The proposed method was successfully applied in the determination of RES in peanut root,with average recoveries of 86.2%-102.1% and relative standard deviations(RSDs) of 3.5%-5.8% at three spiked levels.The developed method is rapid and selective,and is adaptable to the analysis of trace RES in real samples.
