天麻素分子印迹聚合物的吸附和识别性能研究

采用分子印迹技术,以天麻素为模板,合成了对天麻素具有选择性吸附效果的分子印迹聚合物(MIPs)。扫描电镜和平衡吸附实验表明,与空白印迹聚合物(NIPs)相比,MIPs表面粗糙多孔并且有较多的结合位点和较高的吸附容量。在吸附动力学实验中,MIPs在30 min即可吸附最大吸附量的88.38%。在选择性实验中,MIPs对天麻素的吸附量远大于对其结构类似物葡萄糖的吸附量,体现了良好的选择性。研究结果表明,本材料有作为选择性填料来提取分离天麻素的潜能。

Absorption and recognition performance of gastrodin molecularly imprinted polymers

We synthesized molecularly imprinted polymers （MIPs） with selective absorption effect on gastrodin by molecular imprinting technology and gastrodin as a template.Scanning electron microscopy （SEM） and equilibrium absorption experiment reveal that MIPs are rough and porous and have many binding points higher absorption capacity,as compared with non-imprinted polymers （NIPs）.MIPs can reach 88.38％ of their equilibrium absorption capacity within 30 min in absorption kinetics.Absorption capacity of MIPs to gastrodin is much greater than to glucose,so they exhibit better selective absorption capacity.Results indicate that MIPs,selective stuffings,have such potency as extracting and separating gastrodin from natural sources.
