The method disclosed by the invention comprises the following steps: performing cold extraction on China-hemp, performing adsorption by utilizing cannabidiol specific adsorption magnetic molecular polymer pairs, then performing magnetic field separation, and finally performing elution and refining. Or performing cold digestion on the hemp, enriching the crude hemp extract by using macroporous resin or molecular distillation equipment, performing adsorption by using cannabidiol specific adsorption magnetic molecular polymer, then performing magnetic field separation, and finally performing elution. By utilizing a specific separation principle and a magnetic rapid enrichment mode of a cannabidiol specific adsorption magnetic molecular polymer, the use amount of an organic solvent in the existing process is reduced, the use amount of high-value separation consumables is reduced, the process operation is simplified, the process time is shortened, and the requirements of production equipment are reduced; the production efficiency can be obviously improved, the production cost can be obviously reduced, and meanwhile, a brand new method route is provided for CBD extraction and China-hemp active matter separation.
