The invention discloses a preparation method and application of apocynum venetum flavone purifying resin. The preparation method comprises the first step of suspension polymerization, the second step of aminolusis and the third step of amidation. According to the preparation method, by controlling the oil droplet size in the suspension polymerization process, adjusting the heating rate and adjusting the dosage of a divinylbenzene cross-linking agent, an initiator and a pore-foaming agent, the apocynum venetum flavone purifying resin which can effectively improve the purifying effect and effectively remove tannins can be obtained. By the adoption of the purifying resin, the total flavonoid content (measured through a liquid chromatogram) of apocynum venetum extract can be improved to 65wt% or above, and the tannin content is lowered to 15wt% or below.
