The present paper investigated the efficiency of on hemostatic and wound healing activities. leaf extracts were evaluated for their antibacterial and antioxidant effects as well as their flavonoid and polyphenol content. The hydroethanolic extract (EtOH-HOE), showing the most potent antibacterial and antioxidant activities , thanks to its flavonoid and polyphenol richness, was selected for hemostatic and wound healing evaluation. Twenty-four rats completing full-thickness wounds were split into four groups. The wounds were topically treated with saline solution, glycerol, "CICAFLORA," and EtOH-HOE (50 L/mm) until day 11. The wound healing effect was assessed by macroscopic, histological, and biochemical parameters. Rats treated with EtOH-HOE showed fast wound closure (92.39%) compared to the control animals (60.91%) on the 11th day of wounding ( < 0.01). Histopathological and biochemical explorations showed full epidermal regeneration and an improvement of the hydroxyproline content in the EtOH-HOE treated rats. Analysis of fatty acids and sterols by GC-MS showed the presence of unsaturated fatty acids and a high concentration of lupeol known for their involvement in reepithelialization. These results prove the efficiency of EtOH-HOE in wound healing and supported its traditional use.
本文研究了[药物名称]在止血和伤口愈合方面的效果。评估了[药物名称]叶提取物的抗菌和抗氧化作用,以及其类黄酮和多酚含量。由于其富含类黄酮和多酚,水醇提取物(EtOH-HOE)表现出最强的抗菌和抗氧化活性,因此被选择用于止血和伤口愈合评估。将 24 只完成全层伤口的大鼠分为四组。用生理盐水、甘油、“CICAFLORA”和 EtOH-HOE(50 μL/mm)局部治疗伤口,直到第 11 天。通过宏观、组织学和生化参数评估伤口愈合效果。与对照组(第 11 天为 60.91%)相比,用 EtOH-HOE 治疗的大鼠在第 11 天伤口闭合速度更快(92.39%)( < 0.01)。组织病理学和生化研究表明,在 EtOH-HOE 治疗的大鼠中,表皮完全再生,羟脯氨酸含量增加。GC-MS 分析脂肪酸和甾醇表明,存在不饱和脂肪酸和高浓度的羽扇醇,它们已知参与上皮再形成。这些结果证明了 EtOH-HOE 在伤口愈合方面的效果,并支持了其传统用途。
