    Abstract:
    Plant-derived medicinal materials have significant potential and promising applications in wound healing and skin regeneration. This study aims to develop a plant-based extract hydrogel from Bletilla striata (Thunb.Reichb.f.), specifically a glucosyloxybenzyl 2-isobutylmalates extract (B), and characterize its potential effects on wound healing. We synthesized the hydrogel using carbomer (C), glycerol (G), and triethanolamine (T) as the matrix, incorporating B into the hydrogel base, and evaluated its physical and chemical properties. In vitro tests assessed the biocompatibility of the glucosyloxybenzyl 2-isobutylmalates-carbomer-glycerol-triethanolamine (B-CGT) hydrogel and its effects on cell proliferation, migration, and adhesion. Animal model experiments evaluated its potential to promote wound healing. The results showed that the prepared B-CGT hydrogel possessed a good three-dimensional network structure and stability, demonstrating significant free radical scavenging capacity in antioxidant tests. In cell experiments, the B-CGT hydrogel exhibited no potential cytotoxicity and showed good hemocompatibility and promotion of cell proliferation. Animal experiments indicated that wounds treated with the B-CGT hydrogel healed significantly faster, with improved formation of new epithelial tissue and collagen. This study suggests that the developed B-CGT hydrogel is a promising candidate for wound dressings, with excellent physicochemical properties and controlled drug release capabilities, effectively promoting the wound healing process.
