Ginsenosides, which are naturally produced steroid glycosides and triterpene saponins, are thought to have a number of beneficial pharmacological activities and are thus an attractive target for novel extraction methods. Ginsenosides can be isolated from various parts of plants of the Panax genus, but are usually isolated from the roots, and can be purified by column chromatography. In this work, molecularly imprinted polymers were developed for the extraction of ginsenosides, using the ginsenoside analogue lanosterol as a template for the imprinting of magnetic lanosterol-imprinted polymers (MLIPs). Poly(ethylene-co-vinyl alcohol)s, with various ethylene ratios of were used to form MLIP nanoparticles by phase transformation. Magnetic lanosterol-imprinted polymer compositions were then characterized for the absorptivity of ginsenosides, finally, calluses of ginseng were cultured and extracted with magnetic lanosterol-imprinted polymers, and ginsenosides Rg₁ and Rb₁ can be successfully extracted.

人参皂苷是天然产生的甾体糖苷和三萜皂苷，被认为具有许多有益的药理活性，因此是新颖提取方法的有吸引力的靶标。人参皂甙可以从人参属植物的各个部位中分离出来，但是通常是从根部分离出来的，可以通过柱色谱法纯化。在这项工作中，使用人参皂苷类似物羊毛甾醇作为印迹磁性羊毛甾醇印迹聚合物（MLIP）的模板，开发了分子印迹聚合物用于提取人参皂苷。聚（乙烯共-具有不同乙烯比率的-乙烯醇被用于通过相变形成MLIP纳米颗粒。然后对磁性羊毛甾醇印迹聚合物组合物的人参皂甙吸收特性进行了表征，最后，对人参的愈伤组织进行了培养，并用磁性羊毛甾醇印迹聚合物对人参皂苷进行了提取，可以成功提取人参皂苷Rg ₁和Rb ₁。
