Molecularly imprinted polymers (MIPs) are polymers possessing receptor cavities with selective characteristics. The molecularly imprinted polymer of 1,8-cineole on hydroxyl-functionalized multiwall carbon nanotubes was synthesized for selective extraction of 1,8-cineole in water distillates of Artemisia sieberi (sagebrush) and thyme samples. The MIP was synthesized with cineole as template, methacrylic acid as functional monomer, ethylene glycol dimethacrylate as cross-linker and benzoyl peroxide as initiator. The main parameters affecting the synthesis of MIP and also the extraction efficiency of the analyte were optimized. The limit of detection of 1,8-cineole was as low as 0.04 μg/mL, while the dynamic linear range was found to be in the range of 0.125–100 µg/mL. The relative standard deviations (RSDs%) found for samples spiked at 1 and 70 µg/mL were 1.45–4.3%, respectively. The relative recoveries of the spiked samples at the above concentration levels were 93.8–98.2%.

分子印迹聚合物固相萃取法分析百里香和鼠尾草馏出物中的1,8-桉树脑

分子印迹聚合物（MIP）是具有具有选择性特征的受体腔的聚合物。合成了在羟基官能化的多壁碳纳米管上的1,8-桉树脑分子印迹聚合物，用于选择性提取西蒿的水馏出液中的1,8-桉树脑。（鼠尾草）和百里香样品。以桉树脑为模板，甲基丙烯酸为功能单体，乙二醇二甲基丙烯酸酯为交联剂，过氧化苯甲酰为引发剂合成了MIP。优化了影响MIP合成的主要参数以及分析物的提取效率。1,8-桉树脑的检出限低至0.04μg/ mL，而动态线性范围为0.125–100μg/ mL。加标浓度为1和70 µg / mL的样品的相对标准偏差（RSDs％）分别为1.45–4.3％。在上述浓度下加标样品的相对回收率为93.8–98.2％。
