The invention discloses a method and a control system for extracting active ingredients of sweet wormwood by enzymolysis-gradient combination, and particularly relates to the technical field of plant extraction, a high-sensitivity sensor is used for collecting key parameters in enzymolysis reaction, key process parameter characteristics are extracted from high-dimensional data through principal component analysis and a clustering algorithm, and the active ingredients of the sweet wormwood are extracted; establishing a reaction mode library of different extraction risk scores, and identifying an abnormal reaction mode causing artemisinin extraction; evaluating and extracting a risk score in real time by combining real-time and historical data based on a machine learning model, and triggering early warning when the risk exceeds a preset threshold value; the intelligent feedback and prevention and control module applies a control algorithm, automatically adjusts reaction conditions according to risk scores, and forms closed-loop feedback; the concentration and efficiency of artemisinin are monitored in real time through an online high performance liquid chromatography or mass spectrometry system, a verification result is fed back to the extraction risk prediction model, and the system performance is continuously optimized.

The application discloses a method for extracting effective components of radix paeoniae alba, which comprises the following steps: (1) preparing a radix paeoniae alba suspension, and feeding the radix paeoniae alba suspension into a treatment cavity; (2) a needle-plate electrode structure is arranged in the treatment cavity, the needle-plate electrode structure is connected with a high-frequency pulse power supply, and high-voltage pulse treatment is applied to the radix paeoniae alba suspension in the treatment cavity; and (3) the extracted solution after treatment is concentrated under reduced pressure to obtain active extracts. The extraction process can quickly inhibit enzyme activity, prevent paeoniflorin from being hydrolyzed by coexisting enzymes, realize efficient extraction of paeoniflorin at low temperature, and ensure the structural integrity of macromolecular active components such as radix paeoniae alba polysaccharide; and the scheme can improve the extraction efficiency and shorten the production cycle.
