Method for extracting lignan compounds from Chinese magnolia vine fruit

The invention provides a method for extracting lignan compounds from Chinese magnolia vine fruit, and belongs to the technical field of traditional Chinese medicine extracts. The method comprises thefollowing steps: firstly, soaking Chinese magnolia vine fruit sample powder with a proper amount of absolute ethyl alcohol, then extracting lignan compounds in the Chinese magnolia vine fruit througha magnetic stirring assisted supercritical CO2 extraction method to obtain a solid-liquid mixture after the extraction is finished, then transferring the obtained solid-liquid mixture into a centrifugal tube for centrifugal separation, collecting all supernatants, and concentrating under reduced pressure to obtain extract; and performing vacuum drying and crushing on the extract to form powder, thereby obtaining the Chinese magnolia vine fruit lignan extract. According to the method, magnetic stirring and supercritical CO2 extraction are combined for the first time, the magnetic stirring is beneficial to fully mixing t
