Abstract: Molecular imprinted polymer (MIP) was prepared through thermal polymerization by using artemisinin as the template molecule, styrene as the functional monomer, ethylene glycol dimethacrylate (EGDMA) as the cross-linker, and azobisisobutyronitrile (AIBN) as the initiator. Evaluated by static, kinetic, and bonding capacity adsorption tests, the polymer exhibited a special selective rebinding to artemisinin. Scatchard analysis revealed that two different binding sites were formed in the polymers. The novel imprinted polymer was used as a solid-phase extraction (SPE) sorbent for the extraction of artemisinin from Artemisia annua L., followed by HPLC-UV analysis. The maximum static adsorption capacity of the artemisinin-imprinted sorbent for artemisinin was 8.46 mg g-1.The application of artemisinin-imprinted polymers with high affinity and excellent selectivity toward artemisinin in SPE might offer a novel method for the enrichment and determination of the active ingredient in Chinese medicine
