摘要

柚皮苷（Nar）是一种二氢黄酮，被广泛应用于医药、食品工业等领域。本研究通过刻蚀纳米磁性载体并利用计算机辅助材料设计制备了柚皮苷磁性表面分子印迹聚合物（Nar/SMIPs），用于高选择性吸附柚皮苷。Nar/SMIPs 在 30 分钟内的吸附容量高达 37.64 mg-g-1。它们对柚皮苷也表现出极佳的选择性，印记因子为 2.48，而对结构相似的化合物 diosmetin、chrysin 和 alizarin 的选择系数（K）分别为 3.27、2.82 和 3.07。此外，它们在柚子皮提取物中的回收率（89.47-95.95%）和精确度（相对标准偏差：1.38-1.90%）都很高。因此，Nar/SMIPs 在选择性萃取柚皮苷方面具有巨大的潜力。

Nanomaterials Based on Magnetic Surface Molecularly Imprinted Polymers for Specific Recognition of Naringenin

Naringenin (Nar), a dihydroflavone, is widely used in medicine, food industry, and other fields. In this study, naringenin magnetic surface molecularly imprinted polymers (Nar/SMIPs) were prepared by etching nanomagnetic carriers and using computer-aided material design for highly selective adsorption of naringenin. The Nar/SMIPs exhibited a high adsorption capacity of 37.64 mg·g^–1 in 30 min. They also showed excellent selectivity for naringenin, with an imprinting factor of 2.48, and the selection coefficients (K) for structurally similar compounds, diosmetin, chrysin, and alizarin, were 3.27, 2.82, and 3.07, respectively. Furthermore, they demonstrated high recoveries (89.47–95.95%) and precisions (relative standard deviation: 1.38–1.90%) in grapefruit peel extract. Thus, Nar/SMIPs hold tremendous potential for the selective extraction of naringenin.
