Areca catechu polyphenol hydrogel capable of promoting osteoblast proliferation as well as preparation method and application of areca catechu polyphenol hydrogel

The invention discloses areca polyphenol hydrogel capable of promoting osteoblast proliferation as well as a preparation method and application thereof. The preparation method comprises the following steps: (1) adding polyvinyl alcohol into water, heating and dissolving to obtain a PVA solution, dissolving borax into water to obtain a solution B, dissolving areca polyphenol into ethanol-water, and ultrasonically dissolving to obtain an AP solution; (2) mixing the AP solution and the B solution, uniformly stirring to obtain a BA solution, adding the PVA solution into the BA solution, and continuously stirring to obtain PBA pregel; and (3) putting the PBA pregel into a refrigerator, standing and cooling to obtain the target hydrogel. The areca polyphenol hydrogel prepared by the invention not only improves the mechanical properties of polyvinyl alcohol/borax system hydrogel, but also has good self-healing characteristic. Meanwhile, the hydrogel has good biocompatibility, and can promote the proliferation of ost
