The invention discloses a method for separating and purifying pyrroloquinoline quinone in fermentation liquid by a molecularly imprinted solid-phase extraction method. According to the method, the pyrroloquinoline quinone is obtained by performing separation and purification on the fermentation liquid rich in the pyrroloquinoline quinone through a pyrroloquinoline quinone molecularly imprinted polymer. According to the method, silicon dioxide is used as a base material, the pyrroloquinoline quinone is used as a template molecule, methacrylic acid is used as a functional monomer, ethylene glycol dimethacrylate is used as a cross-linking agent, and the pyrroloquinoline quinone molecularly imprinted polymer is obtained through a thermal polymerization technique. Adsorptivity experiments prove that the pyrroloquinoline quinone molecularly imprinted polymer prepared by the method disclosed by the invention has good specific selective properties of adsorbing target objects namely the pyrroloquinoline quinone, and the largest adsorption volume can reach 10mg / mg (molecularly imprinted polymers). Solid-phase extraction is performed on the target object namely the pyrroloquinoline quinone by using the polymer as a solid-phase extraction filling, so that the purpose of efficiently separating and purifying the pyrroloquinoline quinone from the fermentation liquid is realized.
