The invention provides a method for enriching and separating Zanthoxylum bungeanum polyenamide monomers and aroma components, comprising the following steps: (1) molecular distillation enrichment: molecular distillation is performed on Zanthoxylum bungeanum oil, light components and heavy components are separated, and light components are separated. The components are the fragrance components, and the heavy components are the enriched products of polyenamides; (2) dynamic axial compression chromatographic separation: the enriched products of polyenamides obtained in step (1) are dissolved in a solvent, and filtered to carry out Separation by dynamic axial compression chromatography, elution with eluent, and concentration and drying of the eluent to obtain polyenamide monomers. The present invention combines molecular distillation enrichment technology and dynamic axial chromatographic separation technology for the first time. Polyenamide monomers were successfully separated and prepared from the enriched products of polyenamides. |
