Beschreibung
Zusammenfassung:	The invention discloses a preparation method and an extraction method of magnetic molecularly imprinted polymer of larch flavonoid active ingredients, which comprises the following steps: mixing template raw materials with organic solvents and functional monomers, then adding crosslinking agent and initiator, introducing nitrogen to obtain a polymer, magnetically separating and drying under vacuum to obtain a reaction material, eluting and removing the template through Soxhlet extraction method, then removing residual organic matters, and drying, wherein the functional monomer is 4-vinyl pyridine, he template raw material is dihydroquercetin. The molar ratio of template raw material, functional monomer and crosslinking agent is 1: (2-6): (20-30). The preparation method stated is simple and low in cost.
