Summary:The invention discloses a method for preparing a high-purity natural capsaicin monomer. The method comprises the following steps: (1) grinding: taking a certain amount of a capsaicin crude product, and grinding the capsaicin crude product into powder; (2) alcohol dissolution: dissolving the powdery capsaicin-containing crude product obtained in the step (1) in an ethanol water solution, fully stirring for 20-30 minutes to obtain a capsaicin solution, and filtering the capsaicin solution for later use; (3) adsorption: pumping the capsaicin solution filtered in the step (2) into an adsorption resin column; (4) elution: eluting the resin column in the step (3) with an ethanol aqueous solution; and (5) crystallization: concentrating and crystallizing the capsaicin qualified eluent in the step(4) to obtain capsaicin crystals. According to the method for purifying capsaicin, the ethanol aqueous solution is adopted as an elution agent, the process is environmentally friendly, safe and simple, the separation efficien
