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.
