Molecular imprinted polymer ( MIPs ) excellent performance as well as to target specific adsorption in the artificial antibody mimic, catalysis, drug release, solid phase extraction, chromatography, sensors and determination of adsorption and other fields are widely used. The main active compounds of traditional Chinese medicine s conduct is nonyl alcohol. Because the traditional separation material selectivity is poor, the traditional Chinese medicine of direct extraction of kirenol complicated process and low efficiency.

Lanzhou Institute of Chemical Physics Chinese Academy of Sciences Chinese Academy of Sciences northwest characteristics of plant resources, Key Laboratory of chemical researcher Shi Yanping leads the medicine chemical group through non-covalent imprinting method for the synthesis of a new molecular imprinted polymers, and the establishment of a solid phase extraction method should be used in Chinese medicine, the success of Herba Siegesbeckiae extract two terpenoids nonyl alcohol extraction. The prepared molecularly imprinted polymers for the target analyte with good selectivity and adsorption performance, recovery rate of up to 80.9%.

The method is the active ingredients of plant selective extraction and cleaning effective method, can be applied directly to the traditional Chinese medicine Herba Siegesbeckiae nonyl alcohol extraction in complex system.
