Acteoside (ACT) is an important medicinal component, but its content is scarce. To obtain higher purity of ACT, the adsorption method was used to purify it. In this study, a broad-pore-domain hyper-crosslinked polymer (BHP-Kae) was prepared to adsorb ACT from , which is a medicinal plant. BHP-Kae-3 possessed a unique broad-pore-domain structure. This structure reduced the transfer resistance of ACT and facilitated the rapid diffusion of ACT into BHP-Kae-3, increasing the adsorption capacity. In addition, the surface and pore channels of BHP-Kae-3 contained abundant functional groups (-OH, C=O), which provided a large number of adsorption sites and facilitated ACT adsorption, thereby improving selectivity. The experimental results showed that BHP-Kae-3 exhibited a good adsorption capacity for ACT; the adsorption capacity was 105.12 mg/g, and the selectivity was 3.41. This study demonstrates the potential for efficient separation of natural products using broad-pore-domain adsorbents.
毛蕊花糖苷（ACT）是一种重要的药用成分，但其含量稀少。为了获得更高纯度的ACT，采用吸附法对其进行纯化。在本研究中，制备了一种大孔域超交联聚合物（BHP-Kae），用于从药用植物中吸附ACT。BHP-Kae-3具有独特的大孔域结构。这种结构降低了ACT的传质阻力，促进了ACT快速扩散进入BHP-Kae-3，提高了吸附容量。此外，BHP-Kae-3的表面和孔道含有丰富的官能团（-OH、C=O），提供了大量吸附位点，促进了ACT的吸附，从而提高了选择性。实验结果表明，BHP-Kae-3对ACT表现出良好的吸附性能；吸附容量为105.12 mg/g，选择性为3.41。本研究证明了使用大孔域吸附剂高效分离天然产物的潜力。
