▎ 摘　　要

NOVELTY - Hydrogel comprises breviscapinum, chitosan and oxidized graphene composite according to mass ratio of 1-2:3-5:0.5-1, preferably 1.5-1.8:3.5-4.5:0.6-0.8. USE - The hydrogel is useful inhibiting scarring composition (claimed) and wound healing. ADVANTAGE - The hydrogel has hemostasia, bacteriostasis and scar formed radically. The method is simple and convenient, strong practicability, no toxicity and is safe and has good biocompatibility, good biodegradability, good absorbency. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing hydrogel, comprising (i) dissolving the chitosan in acetic acid solution to obtain the chitosan acetic acid solution, mixing the oxidized graphene into the chitosan acetic acid solution to obtain the chitosan/graphene oxide mixed solution, (ii) adding the breviscapine powder into the chitosan/oxidized graphene into the mixed solution, stirring and mixing uniformly, defoaming to obtain the breviscapine/chitosan solution, (iii) blending the additive configured to correspond the additive aqueous solution, mixing evenly additive aqueous solution with breviscapine/chitosan solution, blending, controlling mass ratio of additive aqueous solution and breviscapine/chitosan solution is 2:1-4:1, continuously heating, stirring until the solution is transparent, stopping heating and stirring, removing bubble to obtain hydrogel.
