A supramolecular solvent‐based dispersive liquid‐liquid microextraction was proposed for the extraction and determination of lignans in Forsythiae Fructus combined with high‐performance liquid chromatography. The supramolecular solvent, consisting of tetrabutylammonium bromide and n‐hexanol, was mixed with the sample solution to extract the analytes by a vortex. After accomplishing the extraction,...
The combination of molecular crowding and virtual imprinting was employed to develop a cost‐effective method to prepare molecularly imprinted polymers. By using linear polymer polystyrene as a macromolecular crowding agent, an imprinted polymer recognizable to punicalagin had been successfully synthesized with punicalin as the dummy template. The resulting punicalin‐imprinted polymer presented a remarkable...
