This invention discloses a method for extracting lignin with high phenolic hydroxyl content, belonging to the fields of biomass refining and green chemistry. The method involves pretreating plant fiber raw materials with bio-enzymes to obtain a solid residue; then, the solid residue is extracted and purified using a catalytic eutectic solvent to obtain the lignin with high phenolic hydroxyl content. A two-step strategy of "enzyme pretreatment exposure + catalytic DES directional bond breaking" is employed to extract lignin with high phenolic hydroxyl content from plant fibers. Enzyme pretreatment effectively breaks down the biomass degradation barrier, removing most of the carbohydrates and fully exposing the lignin. This not only results in a lignin yield of over 90% for subsequent DES extraction, but more importantly, it creates an optimal interaction interface for the DES catalyst to selectively break the β-O-4 ether bonds of lignin molecules, thereby generating a large number of phenolic hydroxyl groups in situ, significantly increasing the lignin content to far exceed that of lignin extracted by traditional methods and conventional DES, and producing a product with excellent reactivity.
