[0002] Plant polyphenols are a class of secondary metabolites widely found in plants. Due to their unique chemical structure and diverse biological activities, they exhibit broad application potential in a variety of fields, including food, medicine, cosmetics, agriculture, and forestry. Sawdust, a byproduct of forestry processing, is rich in polyphenolic compounds, particularly tannins, making it a valuable raw material for polyphenol extraction. To efficiently and environmentally friendly utilize this resource, the development of equipment for polyphenol extraction from sawdust is crucial.

[0003] The existing methods for extracting polyphenols mainly include the following four methods:
