                 摘要:以箬叶黄酮碳苷母核木犀草素为虚拟模板分子,结合 Zn(Ⅱ)的配位作用,丙烯酰胺为功能单体,N,N-
                 亚甲基双丙烯酰胺(MBA)为交联剂,乙醇为溶剂制备了木犀草素-Zn(Ⅱ)配位印迹聚合物,并将此聚合物与固
                 相萃取相结合,分离了醇水体系中的箬叶黄酮碳苷。结果表明:当 n(模板分子)∶n(功能单体)∶n(交联
                 剂)=1∶5∶30 时,配位印迹聚合物具有最好的吸附性能,对醇相中木犀草素的吸附容量可达 103.40 mg/g,是
                 未配位印迹聚合物吸附容量(60.61 mg/g)的 1.71 倍,空白印迹聚合物(7.33 mg/g)的 14.11 倍。采用木犀草素
                 -Zn(Ⅱ)配位印迹聚合物分离醇水相中箬叶黄酮碳苷,经一次分离后,荭草苷、异荭草苷、牡荆苷和异牡荆苷的
                 回收率分别为 91.95%、80.87%、60.43%和 63.63%;质量分数分别是粗提物的 55.36、48.89、36.64 和 38.35 倍,
                 4 种黄酮碳苷总质量百分数由提取前的 0.70%提高到 32.68%。

                 Abstract: A series of luteolin-Zn(Ⅱ) complex molecularly imprinted polymers (MIPs) were synthesized in
                 ethanol,    using luteolin (the mother  nucleus  of C-glycosyflavones from  Indicalamus leaf) as  dummy
                 template, acrylamide (AM) as monomer and N, N- methylene diacrylamide (MBA) as cross-linker. And
                 then C-glycosyflavones from  Indicalamus leaf in alcohol-water system  were separated by solid phase
                 extraction using MIPs. The results showed that when n(luteolin-Zn)∶n(AM)∶n(MBA) was 1∶5∶30, the
                 obtained complex molecularly imprinted  polymer possessed the highest adsorption  properties, and the
                                                                             –1
                 adsorption capacity for luteolin from ethanol phase reached 103.40 mg·g , which was 1.71 times that of
                 uncoordinated molecularly imprinted polymer (60.61 mg/g), 14.11 times that of blank polymer (7.33 mg/g).
                 After a separation, the recovery rates of orientin, isoorientin, vitexin and isovitexin were 91.95%, 80.87%,
                 60.43% and 63.63%, compared  with crude extract, the corresponding  mass percents were increased by
                 55.36, 48.89, 36.64 and 38.35 times, respectively. In addition, the total mass percent of four C-glycosyflavones
                 was increased to 32.68% from 0.70% before extraction.
