Acteoside (ACT) was the main bioactive components in phenylethanoid glycosides of . Currently, the development of an efficient method for selectively separating ACT was crucial. Consequently, yolk-shell magnetic mesoporous carbon (YSMMC) was synthesized as a nanofiller to prepare molecularly imprinted membranes (ACT-MIMs) with instant noodles-like structure for selectively separating ACT. The numerous YSMMC were moved to the upper surface of ACT-MIMs by magnetic guidance and constructed the instant noodles-like structure in ACT-MIMs. The instant noodle-like structure increased the surface roughness of ACT-MIMs, which was conducive to improving the effective imprinted interface, increasing the selectivity of ACT-MIMs. In addition, the instant noodle-like structure had dendritic interleaved pathways in ACT-MIMs. The dendritic interleaved pathways can intercept ACT through ACT-MIMs, enhancing the permselectivity of ACT-MIMs. The prepared YSMMC possessed the dendritic shell and interlayer cavity structure can provide a great accommodation space, improving the rebinding capacities of ACT-MIMs. The high permselectivity (14.49), remarkable selectivity (7.52), and excellent rebinding capacity (120.48 mg/g) were achieved for the prepared ACT-MIMs. Thus, the design of ACT-MIMs with the instant noodles-like structure were valuable for selectively separating of bioactive components.

构建类方便面结构分子印迹膜选择性分离类叶升麻苷


Acteoside (ACT) 是苯乙醇苷类中的主要生物活性成分。目前，开发一种有效的选择性分离 ACT 的方法至关重要。因此，合成了蛋黄壳磁性介孔碳（YSMMC）作为纳米填料，制备了具有方便面状结构的分子印迹膜（ACT-MIM），用于选择性分离ACT。众多的YSMMC通过磁力引导移动到ACT-MIM的上表面，并在ACT-MIM中构建方便面状的结构。方便面状结构增加了ACT-MIMs的表面粗糙度，有利于改善有效压印界面，提高ACT-MIMs的选择性。此外，方便面状结构在 ACT-MIM 中具有树突状交错通路。树突状交错通路可以通过 ACT-MIM 拦截 ACT，从而增强 ACT-MIM 的通透选择性。制备的YSMMC具有树枝状壳和层间空腔结构，可以提供很大的容纳空间，提高ACT-MIM的重结合能力。所制备的 ACT-MIM 具有高选择性渗透性 (14.49)、显着的选择性 (7.52) 和出色的再结合能力 (120.48 mg/g)。因此，设计具有类似方便面结构的ACT-MIM对于选择性分离生物活性成分具有重要意义。
