                 Abstract: In recent years, plant-based biomass resources have become a research hotspot due to their wide
                 range of sources, renewability, biodegradability and so on. The preparation or modification of polymers can
                 further alleviate the petrochemical resource crisis and improve the environmental adaptability of polymer
                 materials. Meanwhile, the active functional groups and hydrogen bonds are rich in the plant-based biomass
                 resources, which have attracted much attention for its application in the preparation and modification of
                 self-healing materials. Taking cellulose and lignin as examples, the application of plant-based resources in
                 self-healing materials in recent years are reviewed, and their natural characteristics and their important roles
                 in the preparation of self-healing materials are introduced in detail. In addition, the application principles of
                 dynamic chemical bonds such as Diels-Alder reaction, sulfur-sulfur bond and hydrogen bond in self-healing
                 materials  are discussed from the point of  view of molecular structure.  Finally, the  main challenges and
                 potential solutions for the preparation of self-healing materials by plant-based biomass are put forward, and the
                 research direction of the application of plant-based biomass materials in self-healing materials is prospected.
