Abstract

The invention discloses a high-efficiency extraction system and an extraction method of the alkaloids of cymbidium radix. The discharge port of the pulverizer of the extraction system is connected with the feed port of the reactor, the feed port of the centrifuge is provided with a boiling assembly, the discharge port of the reactor is connected with the feed port of the boiling assembly, the centrifuge is connected with the enrichment assembly in a closed loop, and the centrifugal The discharge port of the machine is connected with the feed port of the elution component, the discharge port of the elution component is provided with a filter membrane and communicated with the feed port of the volatile component, the evaporation port of the volatile component is connected with the condenser, and the discharge port of the volatile component is connected with the feed port of the extraction component The mouth is connected. The extraction method includes the steps of raw material prefabrication, extraction and separation, concentrated enzymolysis, preparation of total alkaloids, extraction and drying. In the present invention, alkaloids are converted into salts by treatment with fenugreek powder and acid water, precipitated, centrifuged, concentrated and filtered, mixed enzymes are added to precipitate fibers and centrifuged, cationic resins are used to replace alkaloids, and ethanol precipitation is used to remove impurities, and ethanol is volatilized to obtain total biological Alkali, the final fractional extraction of monomeric alkaloids.

Description
