摘要
In this study, a poly ([email protected]) composite monolithic column was synthesized using a simple and easy method. By adjusting the ratio of monomers, porogenic agents and cross-linking agents, a macroporous composite monolith composed of metal organic framework (MOF) and ionic liquids (IL) was constructed. It was used as a high-performance solid phase extraction (SPE) sorbent for the extraction of acacetin from medicinal and food homologous plants. The proposed SPE-HPLC method for determination of acacetin had the advantages of high precision (0.06∼1.00 %), wide linear range (0.01∼250 μg mL−1) and low detection limits (3.26 ng mL−1). The poly ([email protected]) monolithic column had excellent repeatability as an adsorbent. After 300 adsorption/desorption cycles, the corresponding chromatographic signal had no obvious change. These results indicated that the poly ([email protected]) composite monolithic column was an ideal adsorbents and that the proposed method had potential for the enrichment and purification of flavonoids from medicinal and food homologous plants.
